Atlassian has rolled out fixes to remediate a critical security vulnerability pertaining to the use of hard-coded credentials affecting [the Questions For Confluence](<https://marketplace.atlassian.com/apps/1211644/questions-for-confluence>) app for Confluence Server and Confluence Data Center.
The flaw, tracked as **CVE-2022-26138**, arises when the app in question is enabled on either of two services, causing it to create a Confluence user account with the username "disabledsystemuser."
While this account, Atlassian says, is to help administrators migrate data from the app to Confluence Cloud, it's also created with a hard-coded password, effectively allowing viewing and editing all non-restricted pages within Confluence by default.
"A remote, unauthenticated attacker with knowledge of the hard-coded password could exploit this to log into Confluence and access any pages the [confluence-users group](<https://confluence.atlassian.com/doc/confluence-groups-139478.html>) has access to," the company [said](<https://confluence.atlassian.com/doc/questions-for-confluence-security-advisory-2022-07-20-1142446709.html>) in an advisory, adding that "the hard-coded password is trivial to obtain after downloading and reviewing affected versions of the app."
Questions for Confluence versions 2.7.34, 2.7.35, and 3.0.2 are impacted by the flaw, with fixes available in versions 2.7.38 and 3.0.5. Alternatively, users can [disable or delete](<https://confluence.atlassian.com/doc/delete-or-disable-users-138318.html>) the disabledsystemuser account.
While Atlassian has pointed out that there's no evidence of active exploitation of the flaw, users can look for indicators of compromise by checking the last authentication time for the account. "If the last authentication time for disabledsystemuser is null, that means the account exists but no one has ever logged into it," it said.
Separately, the Australian software company also moved to patch a pair of critical flaws, which it calls servlet filter dispatcher vulnerabilities, impacting multiple products -
* Bamboo Server and Data Center
* Bitbucket Server and Data Center
* Confluence Server and Data Center
* Crowd Server and Data Center
* Fisheye and Crucible
* Jira Server and Data Center, and
* Jira Service Management Server and Data Center
Successful exploitation of the bugs, tracked as CVE-2022-26136 and CVE-2022-26137, could enable an unauthenticated, remote attacker to bypass authentication used by third-party apps, execute arbitrary JavaScript code, and circumvent the cross-origin resource sharing ([CORS](<https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS>)) browser mechanism by sending a specially crafted HTTP request.
"Atlassian has released updates that fix the root cause of this vulnerability, but has not exhaustively enumerated all potential consequences of this vulnerability," the company [cautioned](<https://confluence.atlassian.com/security/multiple-products-security-advisory-cve-2022-26136-cve-2022-26137-1141493031.html>) in its advisory regarding CVE-2022-26137.
**_Update:_** Atlassian on Thursday warned that the critical Questions For Confluence app vulnerability is likely to be exploited in the wild after the hard-coded password became publicly known, urging its customers to remediate the issue as soon as possible.
"An external party has discovered and publicly disclosed the hardcoded password on Twitter," the company said. "It is important to remediate this vulnerability on affected systems immediately."
The software firm also emphasized that uninstalling the Questions for Confluence app does not address the vulnerability, as the created account does not get automatically removed after the app has been uninstalled. It's instead recommending that users either update to the latest version of the app or manually disable or delete the account.

Atlassian has been a focus for attackers, as it was less than two months ago that we observed exploitation of [CVE-2022-26134 in Confluence Server and Confluence Data Center](<https://www.rapid7.com/blog/post/2022/06/02/active-exploitation-of-confluence-cve-2022-26134/>).\n\n**CVE-2022-26138: Hardcoded password in Questions for Confluence app impacting:**\n\n * Confluence Server\n * Confluence Data Center\n\n**CVE-2022-26136 & CVE-2022-26137: Multiple Servlet Filter vulnerabilities impacting:**\n\n * Bamboo Server and Data Center\n * Bitbucket Server and Data Center\n * Confluence Server and Data Center\n * Crowd Server and Data Center\n * Crucible\n * Fisheye\n * Jira Server and Data Center\n * Jira Service Management Server and Data Center\n\n## CVE-2022-26138: Hardcoded password in Questions for Confluence app\n\nThe most critical of these three is [CVE-2022-26138](<https://confluence.atlassian.com/doc/questions-for-confluence-security-advisory-2022-07-20-1142446709.html>), as it was quickly exploited in the wild once the hardcoded password was released on social media. There is a limiting function here, however, as this vulnerability only exists when the Questions for Confluence app is enabled (and does not impact the Confluence Cloud instance). Once the app is enabled on affected versions, it will create a user account with a hardcoded password and add the account to a user group, which allows access to all non-restricted pages in Confluence. This easily allows a remote, unauthenticated attacker to browse an organization\u2019s Confluence instance. Unsurprisingly, it didn\u2019t take long for Rapid7 to observe exploitation once the hardcoded credentials were released, given the high value of Confluence for attackers who often jump on Confluence vulnerabilities to execute ransomware attacks.\n\n## Affected versions\n\n * Questions for Confluence 2.7.x\n\n * 2.7.34\n * 2.7.35\n * Questions for Confluence\n\n * 3.0.x\n * 3.0.2\n\n## Mitigation guidance\n\nOrganizations using on-prem Confluence should follow Atlassian\u2019s guidance on updating their instance or disabling/deleting the account. Rapid7 recommends organizations impacted by this take steps immediately to mitigate the vulnerability. Atlassian\u2019s advisory also includes information on how to look for evidence of exploitation. An [FAQ](<https://confluence.atlassian.com/kb/faq-for-cve-2022-26138-1141988423.html>) has also been provided.\n\n> Please note: Atlassian\u2019s [Questions For Confluence Security Advisory 2022-07-20](<https://confluence.atlassian.com/doc/questions-for-confluence-security-advisory-2022-07-20-1142446709.html>) has a very important call-out that \u201cuninstalling the Questions for Confluence app does not remediate this vulnerability.\u201d\n\n## CVE-2022-26136 & CVE-2022-26137: Multiple Servlet Filter vulnerabilities\n\nTwo other vulnerabilities were announced at the same time, [CVE-2022-26136 and CVE-2022-26137](<https://confluence.atlassian.com/security/multiple-products-security-advisory-cve-2022-26136-cve-2022-26137-1141493031.html>), which are also rated critical by Atlassian. They both are issues with Servlet Filters in Java and can be exploited by remote, unauthenticated attackers. Cloud versions of Atlassian have already been fixed by the company.\n\nThe list of affected versions is long and can be found on [Atlassian\u2019s Security Advisory](<https://confluence.atlassian.com/security/multiple-products-security-advisory-cve-2022-26136-cve-2022-26137-1141493031.html>).\n\nWhile the impact of these vulnerabilities will vary by organization, as mentioned above, attackers place a high value on many Atlassian products. Therefore, Rapid7 recommends that organizations update impacted product versions as there is no mitigation workaround available.\n\n## Rapid7 customers\n\nInsightVM and Nexpose customers can assess their exposure to CVE-2022-26138 with a remote vulnerability check released on July 29, 2022 (ContentOnly-content-1.1.2602-202207292027).\n\n## Updates\n\n07/29/2022 - 5:30 PM EDT \nUpdated Rapid7 customers section to include information on a new remote vulnerability check.\n\n#### NEVER MISS A BLOG\n\nGet the latest stories, expertise, and news about security today.\n\nSubscribe", "cvss3": {"exploitabilityScore": 3.9, "cvssV3": {"baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "baseScore": 9.8, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "version": "3.1", "userInteraction": "NONE"}, "impactScore": 5.9}, "published": "2022-07-27T19:26:38", "type": "rapid7blog", "title": "Active Exploitation of Atlassian\u2019s Questions for Confluence App CVE-2022-26138", "bulletinFamily": "info", "cvss2": {"severity": "HIGH", "exploitabilityScore": 10.0, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "PARTIAL", "availabilityImpact": "PARTIAL", "integrityImpact": "PARTIAL", "baseScore": 7.5, "vectorString": "AV:N/AC:L/Au:N/C:P/I:P/A:P", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 6.4, "acInsufInfo": false, "obtainUserPrivilege": false}, "cvelist": ["CVE-2022-26134", "CVE-2022-26136", "CVE-2022-26137", "CVE-2022-26138"], "modified": "2022-07-27T19:26:38", "id": "RAPID7BLOG:C45DEEA0736048FF17FF9A53E337C92D", "href": "https://blog.rapid7.com/2022/07/27/active-exploitation-of-atlassians-questions-for-confluence-app-cve-2022-26138/", "cvss": {"score": 7.5, "vector": "AV:N/AC:L/Au:N/C:P/I:P/A:P"}}, {"lastseen": "2022-09-26T16:04:26", "description": "\n\nOn August 24, 2022, Atlassian published [an advisory for Bitbucket Server and Data Center](<https://confluence.atlassian.com/bitbucketserver/bitbucket-server-and-data-center-advisory-2022-08-24-1155489835.html>) alerting users to [CVE-2022-36804](<https://attackerkb.com/topics/iJIxJ6JUow/cve-2022-36804/rapid7-analysis/?utm_source=rapid7-blog&utm_medium=referral&utm_campaign=etr-atlassian-bitbucket>).

There are no public reports of exploitation in the wild as of September 20, 2022 (edit: see note below), but there has been strong interest in the vulnerability from researchers and exploit brokers, and there are now multiple public exploits available. Because the vulnerability is trivially exploitable and the patch is relatively simple to reverse- engineer, it\u2019s likely that targeted exploitation has already occurred in the wild. We expect to see larger-scale exploitation of CVE-2022-36804 soon.\n\n**Note:** Several threat intelligence sources [reported](<https://twitter.com/Shadowserver/status/1573300004072132608>) seeing exploitation attempts in the wild as of September 23, 2022.\n\n**Affected products:** \nBitbucket Server and Data Center 7.6 prior to 7.6.17 \nBitbucket Server and Data Center 7.17 prior to 7.17.10 \nBitbucket Server and Data Center 7.21 prior to 7.21.4 \nBitbucket Server and Data Center 8.0 prior to 8.0.3 \nBitbucket Server and Data Center 8.1 prior to 8.1.3 \nBitbucket Server and Data Center 8.2 prior to 8.2.2 \nBitbucket Server and Data Center 8.3 prior to 8.3.1\n\n## Mitigation guidance\n\nOrganizations that use Bitbucket Server and Data Center in their environments should patch as quickly as possible [using Atlassian's guide](<https://confluence.atlassian.com/bitbucketserver/bitbucket-server-upgrade-guide-776640551.html>), without waiting for a regular patch cycle to occur. Blocking network access to Bitbucket may also function as a temporary stop-gap solution, but this should not be a substitute for patching.\n\n## Rapid7 customers\n\nInsightVM and Nexpose customers can assess their exposure to CVE-2022-36804 with an unauthenticated vulnerability check in the September 20, 2022 content release (`ContentOnly-content-1.1.2653-202209202050`).\n\nA detection rule, `Suspicious Process - Atlassian BitBucket Spawns Suspicious Commands`, was deployed to InsightIDR around 10am ET on September 22, 2022.\n\n## Updates\n\n**September 22, 2022 10:00AM ET** \nUpdated Rapid7 customers section to include information on a new IDR detection rule.\n\n**September 26, 2022 10:30 AM EDT** \nUpdated to reflect reports of exploitation in the wild.\n\n#### NEVER MISS A BLOG\n\nGet the latest stories, expertise, and news about security today.\n\nSubscribe\n\n \n\n\n_**Additional reading:**_\n\n * _[Active Exploitation of Multiple Vulnerabilities in Zimbra Collaboration Suite](<https://www.rapid7.com/blog/post/2022/08/17/active-exploitation-of-multiple-vulnerabilities-in-zimbra-collaboration-suite/>)_\n * _[Active Exploitation of Atlassian\u2019s Questions for Confluence App CVE-2022-26138](<https://www.rapid7.com/blog/post/2022/07/27/active-exploitation-of-atlassians-questions-for-confluence-app-cve-2022-26138/>)_\n * _[Exploitation of Mitel MiVoice Connect SA CVE-2022-29499](<https://www.rapid7.com/blog/post/2022/07/07/exploitation-of-mitel-mivoice-connect-sa-cve-2022-29499/>)_\n * _[CVE-2022-27511: Citrix ADM Remote Device Takeover](<https://www.rapid7.com/blog/post/2022/06/16/cve-2022-27511-citrix-adm-remote-device-takeover/>)_", "cvss3": {"exploitabilityScore": 3.9, "cvssV3": {"baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "baseScore": 9.8, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "version": "3.1", "userInteraction": "NONE"}, "impactScore": 5.9}, "published": "2022-09-20T15:14:26", "type": "rapid7blog", "title": "CVE-2022-36804: Easily Exploitable Vulnerability in Atlassian Bitbucket Server and Data Center", "bulletinFamily": "info", "cvss2": {"severity": "HIGH", "exploitabilityScore": 10.0, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 10.0, "vectorString": "AV:N/AC:L/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 10.0, "acInsufInfo": false, "obtainUserPrivilege": false}, "cvelist": ["CVE-2022-26138", "CVE-2022-27511", "CVE-2022-29499", "CVE-2022-36804"], "modified": "2022-09-20T15:14:26", "id": "RAPID7BLOG:BCF3916E38EC7840E9BABBDD5431352B", "href": "https://blog.rapid7.com/2022/09/20/cve-2022-36804-easily-exploitable-vulnerability-in-atlassian-bitbucket-server-and-data-center/", "cvss": {"score": 10.0, "vector": "AV:N/AC:L/Au:N/C:C/I:C/A:C"}}, {"lastseen": "2022-08-26T21:03:28", "description": "\n\nOver the past few weeks, five different vulnerabilities affecting [Zimbra Collaboration Suite](<https://www.zimbra.com/>) have come to our attention, one of which is unpatched, and four of which are being actively and widely exploited in the wild by well-organized threat actors. We urge organizations who use Zimbra to patch to the **[latest version](<https://wiki.zimbra.com/wiki/Zimbra_Releases>)** on an urgent basis, and to upgrade future versions as quickly as possible once they are released.\n\n## Exploited RCE vulnerabilities\n\nThe following vulnerabilities can be used for remote code execution and are being [exploited in the wild](<https://www.cisa.gov/uscert/ncas/alerts/aa22-228a>).\n\n### CVE-2022-30333\n\n[CVE-2022-30333](<https://nvd.nist.gov/vuln/detail/CVE-2022-30333>) is a path traversal vulnerability in `unRAR`, Rarlab\u2019s command line utility for extracting RAR file archives. CVE-2022-30333 allows an attacker to write a file anywhere on the target file system as the user that executes `unrar`. Zimbra Collaboration Suite uses a vulnerable implementation of `unrar` (specifically, the `amavisd` component, which is used to inspect incoming emails for spam and malware). Zimbra addressed this issue in [9.0.0 patch 25](<https://wiki.zimbra.com/wiki/Zimbra_Releases/9.0.0/P25>) and [8.5.15 patch 32](<https://wiki.zimbra.com/wiki/Zimbra_Releases/8.8.15/P32>) by replacing `unrar` with `7z`.\n\nOur research team has a [full analysis of CVE-2022-30333](<https://attackerkb.com/topics/RCa4EIZdbZ/cve-2022-30333/rapid7-analysis?referrer=blog>) in AttackerKB. A [Metasploit module](<https://github.com/rapid7/metasploit-framework/pull/16796>) is also available. Note that the server **does not** necessarily need to be internet-facing to be exploited \u2014 it simply needs to receive a malicious email.\n\n### CVE-2022-27924\n\nCVE-2022-27924 is a blind Memcached injection vulnerability [first analyzed publicly](<https://blog.sonarsource.com/zimbra-mail-stealing-clear-text-credentials-via-memcache-injection/>) in June 2022. Successful exploitation allows an attacker to change arbitrary keys in the Memcached cache to arbitrary values. In the worst-case scenario, an attacker can steal a user\u2019s credentials when a user attempts to authenticate. Combined with [CVE-2022-27925](<https://nvd.nist.gov/vuln/detail/CVE-2022-27925>), an authenticated remote code execution vulnerability, and [CVE-2022-37393](<https://attackerkb.com/topics/92AeLOE1M1/cve-2022-37393/rapid7-analysis?referrer=blog>), a currently unpatched privilege escalation issue that was publicly disclosed [in October 2021](<https://darrenmartyn.ie/2021/10/27/zimbra-zmslapd-local-root-exploit/>), capturing a user\u2019s password can lead to remote code execution as the root user on an organization\u2019s email server, which frequently contains sensitive data.\n\nOur research team has a [full analysis of CVE-2022-27924](<https://attackerkb.com/topics/6vZw1iqYRY/cve-2022-27924/rapid7-analysis?referrer=blog>) in AttackerKB. Note that an attacker does need to know a username on the server in order to exploit CVE-2022-27924. According to Sonar, it is also possible to poison the cache for _any_ user by stacking multiple requests.\n\n### CVE-2022-27925\n\n[CVE-2022-27925](<https://nvd.nist.gov/vuln/detail/CVE-2022-27925>) is a directory traversal vulnerability in Zimbra Collaboration Suite Network Edition versions 8.8.15 and 9.0 that allows an authenticated user with administrator rights to upload arbitrary files to the system. (Note that Open Source Edition does not have that endpoint and is therefore not vulnerable.) On August 10, 2022, security firm [Volexity published findings](<https://www.volexity.com/blog/2022/08/10/mass-exploitation-of-unauthenticated-zimbra-rce-cve-2022-27925/>) from multiple customer compromise investigations that indicated CVE-2022-27925 was being exploited in combination with a zero-day authentication bypass, now assigned CVE-2022-37042, that allowed attackers to leverage CVE-2022-27925 _without_ authentication.\n\n**Note:** Although the public advisories don't mention it, our testing indicated that Zimbra Collaboration Suite Network Edition (the paid edition) is vulnerable, and the Open Source Edition (free) is not (since it does not have the vulnerable `mboximport` endpoint). Vulnerable versions are:\n\n * Zimbra Collaboration Suite Network Edition 9.0.0 Patch 23 (and earlier)\n * Zimbra Collaboration Suite Network Edition 8.8.15 Patch 30 (and earlier)\n\nOur research team has a [full analysis of CVE-2022-27925](<https://attackerkb.com/topics/dSu4KGZiFd/cve-2022-27925/rapid7-analysis>) in AttackerKB.\n\n### CVE-2022-37042\n\nAs noted above, CVE-2022-37042 is a critical authentication bypass that arises from an incomplete fix for CVE-2022-27925. Zimbra patched CVE-2022-37042 in [9.0.0P26](<https://wiki.zimbra.com/wiki/Zimbra_Releases/9.0.0/P26>) and [8.8.15P33](<https://wiki.zimbra.com/wiki/Zimbra_Releases/8.8.15/P33>).\n\n## Unpatched privilege escalation CVE-2022-37393\n\nIn October of 2021, researcher Darren Martyn [published an exploit](<https://github.com/darrenmartyn/zimbra-slapper/>) for a zero-day [root privilege escalation vulnerability](<https://darrenmartyn.ie/2021/10/27/zimbra-zmslapd-local-root-exploit/>) in Zimbra Collaboration Suite. When successfully exploited, the vulnerability allows a user with a shell account as the `zimbra` user to escalate to root privileges. While this issue requires a local account on the Zimbra host, the previously mentioned vulnerabilities in this blog post offer plenty of opportunity to obtain it.\n\nOur research team tested the privilege escalation in combination with CVE-2022-30333 at the end of July 2022, as well as the fully patched version on August 17, 2022, and found that all versions of Zimbra were affected through at least 9.0.0 P26 and 8.8.15 P33. Rapid7 disclosed the vulnerability to Zimbra on July 21, 2022 and later assigned [CVE-2022-37393](<https://nvd.nist.gov/vuln/detail/CVE-2022-37393>) (still awaiting NVD analysis) to track it. A [full analysis of CVE-2022-37393](<https://attackerkb.com/topics/92AeLOE1M1/cve-2022-37393/rapid7-analysis?referrer=blog>) is available in AttackerKB. A [Metasploit module](<https://github.com/rapid7/metasploit-framework/pull/16807>) is also available.\n\n## Mitigation guidance\n\nWe strongly advise that all organizations who use Zimbra in their environments update to the latest available version (at time of writing, the latest versions available are 9.0.0 P26 and 8.8.15 P33) to remediate known remote code execution vectors. We also advise monitoring [Zimbra\u2019s release communications](<https://wiki.zimbra.com/wiki/Zimbra_Releases>) for future security updates, and patching on an urgent basis when new versions become available.\n\nThe AttackerKB analyses for [CVE-2022-30333](<https://attackerkb.com/topics/RCa4EIZdbZ/cve-2022-30333/rapid7-analysis?referrer=blog>), [CVE-2022-27924](<https://attackerkb.com/topics/6vZw1iqYRY/cve-2022-27924/rapid7-analysis?referrer=blog>), [CVE-2022-27925](<https://attackerkb.com/topics/dSu4KGZiFd/cve-2022-27925/rapid7-analysis>), and [CVE-2022-37393](<https://attackerkb.com/topics/92AeLOE1M1/cve-2022-37393/rapid7-analysis?referrer=blog>) all include vulnerability details (including proofs of concept) and sample indicators of compromise (IOCs). Volexity\u2019s [blog](<https://www.volexity.com/blog/2022/08/10/mass-exploitation-of-unauthenticated-zimbra-rce-cve-2022-27925/>) also has information on how to look for webshells dropped on Zimbra instances, such as comparing the list of JSP files on a Zimbra instance with those present by default in Zimbra installations. They have published [lists of valid JSP files included in Zimbra installations](<https://github.com/volexity/threat-intel/tree/main/2022/2022-08-10%20Mass%20exploitation%20of%20\\(Un\\)authenticated%20Zimbra%20RCE%20CVE-2022-27925>) for the latest version of 8.8.15 and of 9.0.0 (at time of writing).\n\nFinally, we recommend blocking internet traffic to Zimbra servers wherever possible and [configuring Zimbra to block external Memcached](<https://wiki.zimbra.com/wiki/Blocking_Memcached_Attack>), even on patched versions of Zimbra.\n\n## Rapid7 customers\n\nVulnerability checks for all five Zimbra CVEs are available via a content-only update as of August 18, 3pm ET.\n\n**InsightIDR:** Customers should look for alerts generated by InsightIDR\u2019s built-in detection rules from systems monitored by the Insight Agent.

While we definitely had our share of summer fun, our team continued to invest in the product, releasing features and updates like recurring coverage for enterprise technologies, performance enhancements, and more. Let\u2019s take a look at some of the key releases in [InsightVM](<https://www.rapid7.com/products/insightvm/>) and [Nexpose](<https://www.rapid7.com/products/nexpose/>) from Q3. \n\n## [[InsightVM](<https://docs.rapid7.com/insightvm/recurring-vulnerability-coverage/>) and [Nexpose](<https://docs.rapid7.com/nexpose/recurring-vulnerability-coverage/>)] Recurring coverage for VMware vCenter\n\nRecurring coverage provides ongoing, automatic vulnerability coverage for popular enterprise technology and systems. We recently added VMware vCenter to our list.\n\nVMware vCenter Server is a centralized management platform used to manage virtual machines, ESXi hosts, and dependent components from a single host. Last year, vCenter was a significant target for bad actors and became the subject of a [number](<https://www.rapid7.com/blog/post/2021/02/24/vmware-vcenter-server-cve-2021-21972-remote-code-execution-vulnerability-what-you-need-to-know/>) [of](<https://www.rapid7.com/blog/post/2021/09/21/critical-vcenter-server-file-upload-vulnerability-cve-2021-22005/>) zero-days. Rapid7 provided ad hoc coverage to protect you against the vulnerabilities. Now, recurring coverage ensures fast, comprehensive protection that provides offensive and defensive security against vCenter vulnerabilities as they arise.\n\n## [InsightVM and Nexpose] Tune Assistant\n\nThe Security Console in InsightVM and Nexpose contains components that benefit from performance tuning. Tune Assistant is a built-in feature that will calculate performance tuning values based on resources allocated to the Security Console server, then automatically apply those values.\n\nTuning is calculated and applied to all new consoles when the product first starts up, and customers experiencing performance issues on existing consoles can now easily increase their own resources. For more information, read our [docs page](<https://docs.rapid7.com/insightvm/configuring-maximum-performance-in-an-enterprise-environment/>) on configuring maximum performance in an enterprise environment.\n\n\n\n## [InsightVM and Nexpose] Windows Server 2022 Support\n\nWe want to ensure InsightVM and Nexpose are supported on business-critical technologies and operating systems. We added Windows Server 2022, the latest operating system for servers from Microsoft, to our list. The Scan Engine and Security Console can be installed and will be supported by Rapid7 on Windows Server 2022.

InsightVM and Nexpose customers can assess their exposure to many of these CVEs for vulnerability checks, including:\n\n * **Mitel MiVoice Connect Service Appliance | CVE-2022-29499:** An onsite VoIP business phone system, MiVoice Connect had a data validation vulnerability, which arose from insufficient data validation for a diagnostic script. The vulnerability potentially allowed an unauthenticated remote attacker to send specially crafted requests to inject commands and achieve remote code execution. [Learn more about the vulnerability and our response](<https://www.rapid7.com/blog/post/2022/07/07/exploitation-of-mitel-mivoice-connect-sa-cve-2022-29499/>).\n * **\u201cQuestions\u201d add-on for Confluence Application | CVE-2022-26138:** This vulnerability affected \u201cQuestions,\u201d an add-on for the Confluence application. It was quickly exploited in the wild once the hardcoded password was released on social media.

Arbitrary Servlet Filter Bypass (CVE-2022-26136) A remote, unauthenticated attacker can bypass Servlet Filters used by first and third party apps. The impact depends on which filters are used by each app, and how the filters are used. Atlassian has released updates that fix the root cause of this vulnerability, but has not exhaustively enumerated all potential consequences of this vulnerability. Only the following attacks have been confirmed: {*}Authentication bypass{*}. Sending a specially crafted HTTP request can bypass custom Servlet Filters used by third party apps to enforce authentication. A remote, unauthenticated attacker can exploit this to bypass authentication used by third party apps.

This vulnerability can result in authentication bypass and cross-site scripting (CVE-2022-26136).\n\n- A vulnerability which permits a remote unauthenticated attacker to cause additional Servlet Filters to be invoked when the application processes requests or responses & also invoke the Servlet Filter to respond tto CORS requests, resulting in a CORS bypass.\n\nNote that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.", "cvss3": {}, "published": "2023-05-03T00:00:00", "type": "nessus", "title": "Atlassian Jira Service Desk < 4.13.22 Multiple Vulnerabilities", "bulletinFamily": "scanner", "cvss2": {}, "cvelist": ["CVE-2022-26135", "CVE-2022-26136"], "modified": "2023-05-03T00:00:00", "cpe": ["cpe:2.3:a:atlassian:jira_service_desk:*:*:*:*:*:*:*:*"], "id": "WEB_APPLICATION_SCANNING_113887", "href": "https://www.tenable.com/plugins/was/113887", "sourceData": "No source data", "cvss": {"score": 0.0, "vector": "NONE"}}], "atlassian": [{"lastseen": "2023-06-05T15:39:39", "description": "Multiple Servlet Filter vulnerabilities have been fixed in Bamboo Server and Data Center.

Vulnerability Summary\r\n\r\nWhen the [Questions for Confluence app|https://marketplace.atlassian.com/apps/1211644/questions-for-confluence?hosting=server&tab=overview] is enabled on Confluence Server or Data Center, it creates a Confluence user account with the username {{{}disabledsystemuser{}}}. This account is intended to aid administrators that are migrating data from the app to Confluence Cloud. The {{disabledsystemuser}} account is created with a hardcoded password and is added to the {{confluence-users}} group, which allows viewing and editing all non-restricted pages within Confluence [by default|https://confluence.atlassian.com/doc/confluence-groups-139478.html]. A remote, unauthenticated attacker with knowledge of the hardcoded password could exploit this to log into Confluence.\r\n\r\nThe {{disabledsystemuser}} account is configured with a third party email address ({{{}dontdeletethisuser@email.com{}}}) that is not controlled by Atlassian. If this vulnerability has not been remediated per the _Fixes_\u00a0section below, an affected instance\u00a0configured\u00a0to send\u00a0[notifications|https://confluence.atlassian.com/doc/email-notifications-145162.html]\u00a0will email that address.\u00a0One example\u00a0of an email notification is\u00a0[Recommended Updates Notifications|https://confluence.atlassian.com/doc/configuring-the-recommended-updates-email-notification-281480712.html], which contains a report of the top pages from Confluence spaces the user has permissions to view. mail.com, the free email provider that manages the {{dontdeletethisuser@email.com}}\u00a0account, has confirmed to Atlassian that the account has been blocked. This means it cannot be accessed by anyone unauthorized and cannot send or receive any new messages.\r\n\r\n(!) An external party has discovered and publicly disclosed the hardcoded password on Twitter. Refer to the _Remediation_ section below for guidance on how to remediate this vulnerability.\r\nh3. How To Determine If You Are Affected\r\n\r\nA Confluence Server or Data Center instance is affected if it has an active user account with the following information:\r\n * User: {{disabledsystemuser}}\r\n * Username: {{disabledsystemuser}}\r\n * Email: {{dontdeletethisuser@email.com}}\r\n\r\nIf this account does not show up in the list of active users, the Confluence instance is not affected.\r\nh3. Remediation\r\n\r\n(!) Uninstalling the Questions for Confluence app does *not* remediate this vulnerability. The {{disabledsystemuser}} account does not automatically get removed after the app has been uninstalled. If you have verified a Confluence Server or Data Center instance is affected, two equally effective ways to remediate this vulnerability are listed below. (!)\r\nh4. Option 1: Update to a non-vulnerable version of Questions for Confluence\r\n\r\nUpdate the Questions for Confluence app to a fixed version:\r\n * 2.7.x >= 2.7.38\r\n * Versions >= 3.0.5\r\n\r\nFor more information on how to update an app, refer to [Atlassian's documentation|https://confluence.atlassian.com/upm/updating-apps-273875710.html].\r\n\r\nFixed versions of the Questions for Confluence app stop creating the {{disabledsystemuser}} user account, and remove it from the system if it has already been created. Migrating data from the app to Confluence Cloud is now a manual process.\r\n\r\n(!) If Confluence is configured to use a read-only external directory (e.g. Atlassian Crowd), you will need to follow Option 2 below.\r\nh4. Option 2: Disable or delete the {{disabledsystemuser}} account\r\n\r\nSearch for the {{disabledsystemuser}} account and either disable it or delete it. For instructions on how to disable or delete an account (including an explanation of the differences between the two options), refer to [Atlassian's documentation|https://confluence.atlassian.com/doc/delete-or-disable-users-138318.html].\r\n\r\nIf you choose to delete the {{disabledsystemuser}} account, you must also [uninstall|https://confluence.atlassian.com/upm/uninstalling-apps-273875709.html] or upgrade the Questions for Confluence app to a non-vulnerable version. *Failure to do this could result in the account being recreated after it has been deleted.*\r\n\r\nIf Confluence is configured to use a read-only external directory, refer to the [Delete from a read-only external directory, or multiple external directories section|https://confluence.atlassian.com/doc/delete-or-disable-users-138318.html#DeleteorDisableUsers-Deletefromaread-onlyexternaldirectory,ormultipleexternaldirectories]\u00a0from the same document\r\nh3.

We\u2019re excited to see a lot of old friends again to commiserate, hang out, trade stories and generally talk about security. \n\n \n\n\nThroughout the two days of the main conference, we\u2019ll have a full suite of flash talks at the Cisco Secure booth and several sponsored talks. Since this is the last edition of the newsletter before BlackHat starts, it\u2019s probably worthwhile running through all the cool stuff we\u2019ll have going on at Hacker Summer Camp. \n\n \n\n\nOur [booth should be easy enough to find](<https://www.expocad.com/host/fx/ubm/22bhusa/exfx.html>) \u2014 it\u2019s right by the main entrance to Bayside B. If you get to the Trellix Lounge, you\u2019ve gone too far north. Our researchers will be there to answer any questions you have and present on a wide variety of security topics, from research into Adobe vulnerabilities to the privacy effects of the overturn of Roe vs. Wade. Attendees who watch a lightning talk can grab a never-before-seen [Snort 3](<https://snort.org/snort3>)-themed Snorty and our malware mascot stickers, which were a [big hit at Cisco Live this year](<https://twitter.com/TalosSecurity/status/1536821931097305088>). \n\n \n\n\nWe\u2019ll also be over at the Career Center if you want to [come work with us](<https://talosintelligence.com/careers>). Or even if you don\u2019t, word on the street is there\u2019ll be silver and gold Snortys there. And on Thursday the 11th between 10 a.m. and noon local time a Talos hiring manager will be on site reviewing resumes and taking questions. \n\n \n\n\nIf you want more in-depth talks, we\u2019ll have five sponsored sessions between the 10th and 11th. If you want the latest schedule and location on those talks, be sure to [follow us on Twitter](<https://twitter.com/TalosSecurity>) or check out Cisco\u2019s BlackHat event page [here](<https://www.cisco.com/c/en/us/products/security/black-hat-usa.html>). Our sponsored talks cover Talos\u2019 latest work in Ukraine, the growing threat of business email compromise and current trends from state-sponsored actors. Make sure to catch all five of them. \n\n \n\n\nAnd if you liked our speakeasy at Cisco Live, you'll love the next secret we have in store at the BlackHat booth. Swing by and ask us about it. \n\n \n\n\nFor anyone sticking around for DEF CON, we\u2019ll also have a presence there with Blue Team Village. Drop any questions in the [Blue Team Village Discord](<https://www.blueteamvillage.org/>) for us, and be sure to attend the BTV Pool Party on Aug. 12 from 8 \u2013 11 p.m. local time. \n\n \n\n\nTo stay up to date on all things Talos at both conferences, be sure to follow us on social media. - \n\n\n \n\n## The one big thing \n\n> \n\n\nCisco Talos recently discovered [a new attack framework called \"Manjusaka\"](<https://blog.talosintelligence.com/2022/08/manjusaka-offensive-framework.html>) being used in the wild that could be the next evolution of Cobalt Strike \u2014 and is even advertised as so. This framework is advertised as an imitation of the Cobalt Strike framework. Although we haven't observed widespread usage of this framework in the wild, it has the potential to be adopted by threat actors all over the world. \n\n\n> ### Why do I care? \n> \n> Our researchers discovered a fully functional version of the command and control (C2), written in GoLang with a User Interface in Simplified Chinese, that\u2019s freely available and can generate new implants with custom configurations with ease. This increases the likelihood of wider adoption of this framework by malicious actors. If you\u2019re a defender of any kind, you want to stay up on the latest tools attackers are likely to use. And since Cobalt Strike is already one of the most widely used out there, it\u2019s safe to assume any evolution of it is going to draw some interest. \n> \n> ### So now what? \n> \n> Organizations must be diligent against such easily available tools and frameworks that can be misused by a variety of threat actors. In-depth defense strategies based on a risk analysis approach can deliver the best results in the prevention of this framework. Talos also released Snort rule 60275 and ClamAV signature Win.Trojan.Manjusaka-9956281-1 to detect the use of Manjusaka. \n\n> \n> \n\n## Other news of note\n\n \n\n\nEverything from convenience stores to government websites in Taiwan saw an uptick in cyber attacks this week after U.S. House Speaker Nancy Pelosi visited the country this week. She was the U.S.\u2019 highest-ranking official to visit there in more than 20 years. However, many of the attacks appeared to be from low-skilled attackers and some could even be attributed to a normal uptick in traffic from a busy news day. China could still retaliate for the visit with a cyber attack against Taiwan or the U.S., as the Chinese government has voiced its displeasure over Pelosi\u2019s actions and launched several kinetic warfare exercises. ([Reuters](<https://www.reuters.com/technology/7-11s-train-stations-cyber-attacks-plague-taiwan-over-pelosi-visit-2022-08-04/>), [Washington Post](<https://www.washingtonpost.com/politics/2022/08/03/those-pelosi-inspired-cyberattacks-taiwan-probably-werent-all-they-were-cracked-up-be/>)) \n\nThe U.S. Cybersecurity and Infrastructure Security Agency is warning that attackers are actively exploiting a critical vulnerability in Atlassian Confluence disclosed last week. CISA added CVE-2022-26138, a hardcoded password vulnerability in the Questions for Confluence app, to its list of Known Exploited Vulnerabilities on Friday. Adversaries can exploit this vulnerability to gain total access to data in on-premises Confluence Server and Confluence Data Center platforms. U.S. federal agencies have three weeks to patch for the issue under CISA\u2019s new guidance.

The infamous SharpTongue group uses the SHARPEXT malware to target organizations in the U.S., Europe and South Korea that work on nuclear weapons and other topics that North Korea sees as relevant to its national security. SHARPEXT installs a Google Chrome extension that allows the attackers to bypass users\u2019 Gmail multi-factor authentication and passwords, eventually entering the inbox and reading and downloading email and attachments. Other North Korean actors continue to use fake LinkedIn applications to apply for remote jobs, hoping to eventually steal cryptocurrency and fund the country\u2019s weapons program.

This is the second episode of Vulnerability Management news and publications. In fact, this is a collection of my posts from the [avleonovcom](<https://t.me/avleonovcom>) and [avleonovrus](<https://t.me/avleonovrus>) telegram channels. Therefore, if you want to read them earlier, subscribe to these channels.\n\n_The main idea of \u200b\u200bthis episode. Microsoft is a biased company. In fact, they should now be perceived as another US agency. Does this mean that we need to forget about Microsoft and stop tracking what they do? No, it doesn't. They do a lot of interesting things that can at least be researched and copied. Does this mean that we need to stop using Microsoft products? In some locations (you know which ones) for sure, in some we can continue to use such products if it is reasonable, but it's necessary to have a plan B. And this does not only apply to Microsoft. So, it's time for a flexible approaches. Here we do it this way, there we do it differently. It seems that rather severe fragmentation of the IT market is a long-term trend and it's necessary to adapt to it._\n\nAlternative video link (for Russia): <https://vk.com/video-149273431_456239097>\n\nWhat's in this episode:\n\n 1. Microsoft released a propaganda report, what does this mean for us?\n 2. Microsoft released the Autopatch feature, is it a good idea to use it?\n 3. Ridiculous Vulnerability: Hardcoded Password in Confluence Questions\n 4. The new Nessus Expert and why it's probably Tenable's worst release\n 5. Rapid7 Nexpose/InsightVM features added in Q2 2022: what's good and what's weird\n 6. Palo Alto: Malicious scan 15 minutes after CVE is released. Oh really?\n 7. 6 groups of vulnerabilities that are most often used in attacks, according to Palo Alto, and the end of IT globalization\n\n## Microsoft released a propaganda report, what does this mean for us?\n\nLet's start with the most important topic. Microsoft [released a propaganda report](<https://query.prod.cms.rt.microsoft.com/cms/api/am/binary/RE50KOK>) about the evil Russians and how they (Microsoft) defend one well-known country. I usually avoid such topics, but in this case, I just can't.\n\n 1. Most of the report is "water" and unproven "highly-likely" stuff. It's boring to read. More than half of the report is not about cyber attacks at all, but about propaganda/disinformation "attacks" in media, social networks, etc. With strange historical digressions. For example, they give a photo of some article from an Indian newspaper of the 1980s and write that this publication was organized by the KGB. I'm not kidding, look at page 12.\n 2. On the other hand, the most important thing in this report is not what is written, but who released it. It's not mainstream media, it's not a government agency like the NSA or CIA, it's Microsoft - a global IT vendor that should, in theory, be more or less neutral. And now they are releasing such reports! If you still believe Microsoft is a non-government commercial company, look through this report. This position is the most official, the foreword was written by the current president of Microsoft.\n 3. From a technical point of view, it is interesting that the state IT infrastructure was transferred to the cloud and Microsoft technologies (Defender for Endpoint?) were used to protect it. Almost all technical information is on the 9th page of the report.\n 4. They write about 2 important security options. The first is that Microsoft made a free Vulnerability Management for them. "The first has been the use of technology acquired from RiskIQ that identifies and maps organizational attack surfaces, including devices that are unpatched against known vulnerabilities and therefore are the most susceptible to attack." It's not entirely clear how they did it. They could just connect hosts to Defender for Endpoint. But perhaps they massively activated the collection of data from hosts in some other way.\n 5. The description of the second protection option hints at the existence of a such non-standard methods: "MSTIC recognized that XXX malware could be mitigated meaningfully by turning on a feature in Microsoft Defender called controlled folder access. This typically would require that IT administrators access devices across their organization, work made more difficult and potentially even dangerous in ZZZ conditions. The YYY government therefore authorized Microsoft through special legal measures to act proactively and remotely to turn on this feature across devices throughout the government and across the country." And here it is not so important that Microsoft set up controlled folder access, it is important how they did it. It turns out that MS can massively remotely tweak security options if the government of a certain country has allowed them to do so. Wow! And what else can they do, on which hosts and under what conditions?\n 6. The main concern, of course, is that Microsoft products, including cloud-based security services, are still widely used in Russian organizations. And not only in Russia, but also in other countries that have some disagreements with US policy. Such publications confirm that Microsoft is a highly biased and unstable IT vendor, and something needs to be done about it quickly.\n\nAnd it would be fair to ask: "Weren't you, Alexander, promoting Microsoft's security services? And now you've turned against them?" \n\nAnd it's easy to point to some posts from my blog:\n\n 1. [Microsoft security solutions against ransomware and APT](<https://avleonov.com/2017/12/20/microsoft-security-solutions-against-ransomware-and-apt/>) (the best business breakfast I've ever had - the catering was top notch )\n 2. [Microsoft Defender for Endpoint: Why You May Need It and How to Export Hosts via API in Python](<https://avleonov.com/2021/02/19/microsoft-defender-for-endpoint-why-you-may-need-it-and-how-to-export-hosts-via-api-in-python/>)\n 3. [Getting Hosts from Microsoft Intune MDM using Python](<https://avleonov.com/2021/06/09/getting-hosts-from-microsoft-intune-mdm-using-python/>)\n 4. [How to get Antivirus-related Data from Microsoft Defender for Endpoint using Intune and Graph API](<https://avleonov.com/2021/08/16/how-to-get-antivirus-related-data-from-microsoft-defender-for-endpoint-using-intune-and-graph-api/>)\n 5. [Microsoft Defender for Endpoint: The Latest Versions of Antivirus Engine & Signatures](<https://avleonov.com/2021/09/14/microsoft-defender-for-endpoint-the-latest-versions-of-antivirus-engine-signatures/>)\n\nIt's paradoxical, but I don't have a post about exporting vulnerabilities from Defender for Endpoint.  I was going to make a post about it, but there were always more important topics. \n\nWhat can I say. I still think that Defender for Endpoint is a cool and user-friendly solution. Although sometimes it may be buggy. I also think it's logical to use your OS vendor's security services. Just because you already have complete trust in your OS vendor. Right? \u0410nd other OS vendors should provide security services, as Microsoft does. But the question is what to do if it has become very difficult to trust your OS vendor? To put it mildly.\n\nNot to say that I did not [write about such risks](<https://avleonov.com/2017/12/20/microsoft-security-solutions-against-ransomware-and-apt/>) at all:\n\n"It will be a difficult decision to store this critical data in Microsoft cloud. Even with Microsoft\u2019s guarantees that all the data is stored securely and they touch it with AI only."\n\nBut of course this was not enough. And 5 years ago, things looked very different. \n\u00af_(\u30c4)_/\u00af\n\n## Microsoft released the Autopatch feature, is it a good idea to use it?\n\nContinuing the topic of Microsoft security services. In mid-July, Microsoft [released the Autopatch feature](<https://www.bleepingcomputer.com/news/microsoft/microsoft-windows-autopatch-is-now-generally-available/>) for Windows 10/11 with Enterprise E3 and E5 licenses (not regular, but more expensive licenses). Also [Hybrid Azure Active Directory must be configured](<https://www.theregister.com/2022/07/12/windows_auopatch_live/>). But if everything is purchased and configured properly, then updates for MS products, drivers and other software (in perspective) can be automatically installed from the MS cloud. And it will be more often than once a month. And in the correct way. If you install all updates on all hosts at the same time, there will be a high risk of mass failures. Therefore, patches will be installed gradually. If a failure is detected, the system administrator will be able to react and roll back the problematic patch.\n\n"The 'test ring' contains a minimum number of devices, the 'first ring' roughly 1% of all endpoints in the corporate environment, the 'fast ring' around 9%, and the 'broad ring" the rest of 90% of devices. \nThe updates get deployed progressively, starting with the test ring and moving on to the larger sets of devices after a validation period that allows device performance monitoring and pre-update metrics comparison. \nWindows Autopatch also has built-in Halt and Rollback features that will block updates from being applied to higher test rings or automatically rolled back to help resolve update issues."\n\nIs it convenient? Yes, of course it's convenient. Is it dangerous? Well, it depends on trust in the vendor, faith in vendor's stability and security. Speaking of Microsoft, this can be very controversial for many organizations in many locations. \n\nBut in general, along with Defender for Endpoint (EDR, VM) and Intune this Autopatch feature looks like a step in the right direction for the OS vendor. At least if we're talking about desktops. If you trust your OS vendor, it makes sense to trust that vendor's services to make life easier for system administrators and security guys. I don't know if vendors of commercial Linux distributions, including Russian ones, are thinking about this, but it seems it makes sense to take such concepts from MS.\n\nOn the other hand, such Autopatch is not a panacea of course. Everything is not so trivial with updating third-party software. But MS seems to have a lot of resources to gradually move in this direction. Vulnerability detection for third-party software in Defender for Endpoint works quite well, which is also not an easy task. Therefore, I think they will be able to update such software in future. If [Qualys can](<https://www.qualys.com/company/newsroom/news-releases/usa/qualys-introduces-zero-touch-patching-for-vulnerability-remediation/>), then MS will handle this as well.\n\n## Ridiculous Vulnerability: Hardcoded Password in Confluence Questions\n\nThere has been a lot of news about [Confluence vulnerabilities](<https://confluence.atlassian.com/security/july-2022-atlassian-security-advisories-overview-1142446703.html>) this week. Atlassian has released three of them.\n\n[CVE-2022-26136 & CVE-2022-26137](<https://confluence.atlassian.com/security/multiple-products-security-advisory-cve-2022-26136-cve-2022-26137-1141493031.html>): Multiple Servlet Filter vulnerabilities (Authentication bypass, XSS, Cross-origin resource sharing bypass). Many Atlassian products are vulnerable. Not only Confluence and JIRA, but also Bitbucket for example. Everything is clear here, such installations need to be patched. And, ideally, it's time to stop using Atlassian products if you live and work in certain locations, because this vendor is unstable.\n\n[CVE-2022-26138](<https://confluence.atlassian.com/doc/questions-for-confluence-security-advisory-2022-07-20-1142446709.html>): Hardcoded password in Confluence Questions. This vulnerability is now the most hyped and ridiculous. If you install the optional Confluence Questions app, this will create a disabledsystemuser user with a hardcoded password. And this user is not disabled!  The password is already publicly available. If you are logged in as this user, you can read the pages accessible by the confluence-users group. Well, isn't it funny?  This can be fixed by patching or blocking/deleting the user.\n\nWhat can be said here:\n\n 1. Plugins and extensions are evil and usually the most vulnerable. Try to avoid them.\n 2. This is how backdoors in software can look like. The exploitation is very simple, and the vendor can always say that "oh, sorry, that was a bug".\n 3. Those who make Confluence and similar services available on the network perimeter are their own enemies.\n\n## The new Nessus Expert and why it's probably Tenable's worst release\n\nTenable [introduced Nessus Expert](<https://www.tenable.com/blog/introducing-nessus-expert-now-built-for-the-modern-attack-surface>). They have Nessus Professional, and now there will be Nessus Expert with new features:\n\n 1. [Infrastructure as Code Scanning](<https://youtu.be/Ks5XN0ZpzBw>). In fact, they added [Terrascan](<https://runterrascan.io/>) (acquired this year) to Nessus. So far, it looks very sloppy. This is a separate independent tab in the menu and scan results cannot be viewed in the GUI and can only be downloaded as Json file.\n 2. [External attack surface scanning](<https://youtu.be/_TYvN_GS-AA>). They took these features from [Bit Discovery](<https://www.whitehatsec.com/bit-discovery/>) (also acquired this year). You can run a scan that will look for subdomains for a domain. But only for 5 domains per quarter. If you want more, you need to pay extra. Not to say that this is some kind of exclusive feature. The results can be viewed in the GUI. But that's all. There is no synergy with the usual functionality of Nessus.\n\nThe press release recalls how [Renaud Deraison](<https://t.me/avleonovcom/966>) released first Nessus 24 years ago. But under him, and even more so under Ron Gula, there were no such terrible releases with freshly bought functionality, attached to the main product "with blue electrical tape". And such a Frankenstein monster could never be presented as a new product. Sadness and marketing. Let's see if it gets better with time.\n\n## Rapid7 Nexpose/InsightVM features added in Q2 2022: what's good and what's weird\n\nI looked at the new features in [Rapid7 Nexpose/InsightVM added in Q2 2022](<https://www.rapid7.com/blog/post/2022/07/28/whats-new-in-insightvm-and-nexpose-q2-2022-in-review/>). Some changes are like "OMG, how did they live without it?!"\n\nThey just added support for CVSS v3 severity in dashboards. CVSS v3 was released in June 2015. CVSS v3 data has been available in NVD since 2017. And now, 5 years after that, Rapid7 decided to take into account these data as well? Well, ok.\n\nOr that they used to have such weird patching dashboards that progress on the Remediation Project was only visible when the patches were applied to all assets. And now it's better: "Yes, this means customers no longer have to wait for all the affected assets to be remediated to see progress". Indeed, better late than never.\n\nRapid7 just added support for AlmaLinux and Rocky Linux. Although stable versions of these distributions appeared more than a year ago and are already actively used in enterprise businesses as a replacement for CentOS. It turns out that Rapid7 clients have just now got the opportunity to scan these distributions.\n\nRapid7 use the term "recurring coverage" for supported software products. And they have a [public list of such products](<https://docs.rapid7.com/insightvm/recurring-vulnerability-coverage/>). "The following software list encompasses those products and services that we are specifically committed to providing ongoing, automated coverage". The list is not very big, but it's cool that it's public.\n\nOn the other hand, there are cool features. At least one, [Scan Assistant](<https://docs.rapid7.com/insightvm/scan-assistant/>). This feature was introduced in December last year, but now it has been improved. This is an agent that does not collect or analyze data, but is only needed for authentication. It solves the problems of using system accounts for scanning, which can be very risky if the scanner host or one of the targets is compromised. This way you can install Scan Assistant on hosts and Vulnerability Scanner will authenticate to hosts using certificates rather than real system accounts.\n\n"Scan Assistant, a lightweight service deployed on an asset that uses digital certificates for handshake instead of account-based credentials; This alleviates the credential management headaches VM teams often encounter."\n\nThis is a cool and useful feature. As far as I know, other VM vendors do not have this. In Q2, Rapid7 added some automation for updating this Scan Assistant and rotating certificates. It's cool that the functionality is evolving. But for now, it's only for Windows.\n\nAnd there are updates that did not cause any special emotions in me. These are, for example, Asset correlation for Citrix VDI instances and vulnerability detection for Oracle E-Business Suite and VMware Horizon. They added and it's good.\n\n## **Palo Alto: Malicious scan 15 minutes after CVE is released. Oh really?**\n\nThe ["Palo Alto 2022 Unit 42 Incident Response Report" makes the amusing claim](<https://unit42.paloaltonetworks.com/incident-response-report/>) that attackers typically start scanning organizations' perimeters for vulnerabilities 15 minutes after a CVE is published.\n\nJust like this:\n\n"The 2021 Attack Surface Management Threat Report found that attackers typically start scanning for vulnerabilities within 15 minutes of a CVE being announced."\n\nThey do not write how exactly they got these 15 minutes. Or I didn't find it. But apparently they could detect attempts to exploit some specific vulnerabilities. They could use honeypots or IDS for this. And then they could get the difference between the timestamp for exploitaition and the timestamp for vulnerability publication.\n\n[There is an example](<https://unit42.paloaltonetworks.com/cve-2022-1388/>) that 5 days after some vulnerability was published, they released a detection signature. And in 10 hours, they collected two and a half thousand attempts to exploit this vulnerability.\n\n"For example, Palo Alto Networks released a Threat Prevention signature for the F5 BIG-IP Authentication Bypass Vulnerability (CVE-2022-1388), and within just 10 hours, the signature triggered 2,552 times due to vulnerability scanning and active exploitation attempts".\n\nIt's cool of course. But still, the signature was not released immediately. Therefore, it is difficult to say exactly when the malicious scans began.\n\nBut that's not the point. It is not so important whether the scans really start after 15 minutes or some time later. The fact is that attackers monitor the news flow about vulnerabilities. And the fact that they are motivated to scan your perimeter more often than you. And they are motivated to use non-standard checks for this. Not just the ones in your commercial vulnerability scanner.\n\nTherefore, there are only two options. You can compete in speed with attackers. Or you may know and control your perimeter far better than any outside researcher can. This means that you must understand why a particular service is needed on the perimeter. And whenever possible, try to minimize the number of such services as much as possible. For such services, you should specifically monitor security bulletins and start responding even before detection checks appear in vulnerability scanners. And of course before the media starts screaming about this vulnerability.\n\nOf course, it's easier said than done.\n\n## 6 groups of vulnerabilities that are most often used in attacks, according to Palo Alto, and the end of IT globalization\n\nIn the same "[Palo Alto 2022 Unit 42 Incident Response Report](<https://unit42.paloaltonetworks.com/incident-response-report/>)" there is one more interesting point. Groups of vulnerabilities that were most often used in attacks. "For cases where responders positively identified the vulnerability exploited by the threat actor, more than 87% of them fell into one of six CVE categories.".\n\nCVE categories:\n\n * 55% Microsoft Exchange ProxyShell (CVE-2021-34473, CVE-2021-34523, CVE-2021-31207)\n * 14% Log4j\n * 7% SonicWall CVEs\n * 5% Microsoft Exchange ProxyLogon (CVE-2021-26855, CVE-2021-26857, CVE-2021-26858, CVE-2021-27065)\n * 4% Zoho ManageEngine ADSelfService Plus (CVE-2021-40539)\n * 3% Fortinet CVEs\n * 13% Other\n\nOn the one hand, this can be used to prioritize vulnerabilities. And also to identify software and software groups that need special monitoring. I would also like to look at the vulnerabilities in the Other category. But unfortunately they are not included in the report.\n\nOn the other hand, it shows how all these vulnerabilities and incidents depend on a particular region. Well of course Microsoft Exchange is used everywhere. Log4j has also affected almost every organization in one way or another. Perhaps in our region, I mean in Russia, some organizations use Fortinet. But SonicWall and Zoho look absolutely exotic. And in those locations where Unit 42 solves incident response cases, these are very important vendors and products.\n\nOr we can remember [last year's story with Kaseya VSA](<https://avleonov.com/2021/07/05/last-weeks-security-news-printnightmare-kaseya-intune-metasploit-docker-escape/>). Thousands of companies have been affected by the ransomware. But again, it was not in our region and therefore it was not particularly interesting for us.\n\nTaking into account the exodus of Western vendors from the Russian IT market, the landscapes "here" and "there" will differ more and more. More and more incidents in Russia, will occur due to vulnerabilities in our local software. In software that Western information security vendors may never have heard of. BTW, have you heard about [1C](<https://en.wikipedia.org/wiki/1C_Company>) ([Odin-Ass](<https://pikabu.ru/story/rossiyskiy_ryinok_programmnogo_obespecheniya_takoy_strannyiy_3895019>) )? And it works both ways. Does this mean that in Russia, we will need Vulnerability Management solutions focused on our Russian IT realities? Well apparently yes. And something tells me that this will not only happen in Russia.\n\nIt seems that the time of total globalization in IT is running out. And the ability of VM vendors to relatively easily take positions in new regions is also disappearing. The great fragmentation is coming. But it will be even more interesting that way.

In June 2022, a critical severity OGNL Remote Code Execution vulnerability was disclosed (CVE-2022-26134). More recently, CVE-2022-26138 was disclosed on social media platforms in July 2022.\n\nIn CVE-2022-26138, a Confluence user account is created by the Questions for Confluence app with hardcoded credentials stored inside the plugin jar file available on [Atlassian packages](<https://packages.atlassian.com/maven-atlassian-external/com/atlassian/confluence/plugins/confluence-questions/3.0.2/>). An attacker with knowledge of these credentials could log into the Confluence application and access all contents within the confluence-users group. [Atlassian](<https://confluence.atlassian.com/doc/questions-for-confluence-security-advisory-2022-07-20-1142446709.html>) has rated the vulnerability "critical" and highlighted that the vulnerability is being exploited in the wild.\n\nDue to the nature of this vulnerability, it can only be verified remotely by logging into the Confluence application with the hardcoded credentials. Traditional open source scanners and scripts are checking for the Location HTTP response header and 302 status code to verify the credentials, which could result in false positives. [Qualys Web Application Scanning](<https://www.qualys.com/apps/web-app-scanning/>) has released QID 150556 that confirms the vulnerability detection in two steps. The detection takes an additional step to verify the valid credentials by navigating to the user profile page and verifying that the correct page is returned. This check is much more efficient in comparison to open source scanners and eliminates any possibility of false positives.\n\n## About CVE-2022-26138\n\nAccording to Confluence's [Questions for Confluence Security Advisory](<https://confluence.atlassian.com/doc/questions-for-confluence-security-advisory-2022-07-20-1142446709.html>), both Confluence Server and Confluence Data Center products using affected versions of the Questions for Confluence app are impacted by CVE-2022-26138.\n\nAffected versions :\n\nQuestions for Confluence 2.7.x| 2.7.34 \n2.7.35 \n---|--- \nQuestions for Confluence 3.0.x| 3.0.2 \n \n## Hardcoded Credentials Vulnerability\n\nAffected versions of the Questions for Confluence app, when installed on a Confluence application, create a user account with username `disabledsystemuser` and password `disabled1system1user6708` and the account is added to confluence-users group, which allows viewing and editing all non-restricted pages within Confluence [by default](<https://confluence.atlassian.com/doc/confluence-groups-139478.html>). A remote attacker can easily leverage these credentials to browse sensitive contents within the Confluence application.\n\nThese hardcoded credentials are stored in `default.properties` file inside a [`confluence-questions-X.X.X.jar` file](<https://packages.atlassian.com/maven-atlassian-external/com/atlassian/confluence/plugins/confluence-questions/3.0.2/>), as shown below.\n\n\n\n## Detecting the Vulnerability with Qualys Web Application Scanning\n\nExisting Qualys customers can detect CVE-2022-26138 on their target Confluence instance with Qualys Web Application Scanning (WAS) using the following Qualys ID (QID):\n\n * 150556 : Atlassian Confluence Server and Data Center : Questions for Confluence App - Hardcoded Credentials (CVE-2022-26138)\n\nThe QID is part of the core category. A vulnerability scan with a core or custom search list including the QID in the options profile will flag all vulnerable applications, as shown below.\n\n\n\n### Qualys WAS Report\n\nOnce the vulnerability is successfully detected by Qualys WAS, the user will see similar results in the vulnerability scan report, as shown here:\n\n\n\n### Solution & Mitigation\n\nTo remediate this vulnerability, any organization using the Questions for Confluence app is advised to ensure the following:\n\n * Upgrade to Version 2.7.x >= 2.7.38 (compatible with Confluence 6.13.18 through 7.16.2) and Versions >= 3.0.5 (compatible with Confluence 7.16.3 and later)\n * Disable or delete the disabledsystemuser account\n\nPlease note that uninstalling the Questions for Confluence app does not remediate this vulnerability. The disabledsystemuser account does not automatically get removed after the app has been uninstalled. It is possible for this account to be present if the Questions for Confluence app was previously installed. It is advised to check the list of active users to ensure the Confluence instance is not affected.\n\n### Credit\n\n**Confluence Security Advisory:** <https://confluence.atlassian.com/doc/questions-for-confluence-security-advisory-2022-07-20-1142446709.html>\n\n### CVE Details:\n\n * <https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-26138>\n * <https://nvd.nist.gov/vuln/detail/CVE-2022-26138>", "cvss3": {"exploitabilityScore": 3.9, "cvssV3": {"baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "baseScore": 9.8, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "version": "3.1", "userInteraction": "NONE"}, "impactScore": 5.9}, "published": "2022-08-17T10:12:53", "type": "qualysblog", "title": "Atlassian Confluence: Questions for Confluence App Hardcoded Credentials Vulnerability (CVE-2022-26138)", "bulletinFamily": "blog", "cvss2": {"severity": "HIGH", "exploitabilityScore": 10.0, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "PARTIAL", "availabilityImpact": "PARTIAL", "integrityImpact": "PARTIAL", "baseScore": 7.5, "vectorString": "AV:N/AC:L/Au:N/C:P/I:P/A:P", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 6.4, "acInsufInfo": false, "obtainUserPrivilege": false}, "cvelist": ["CVE-2022-26134", "CVE-2022-26138"], "modified": "2022-08-17T10:12:53", "id": "QUALYSBLOG:F9C2629D40A6DC7640DB3D6BD4FB60B3", "href": "https://blog.qualys.com/category/vulnerabilities-threat-research", "cvss": {"score": 7.5, "vector": "AV:N/AC:L/Au:N/C:P/I:P/A:P"}}, {"lastseen": "2022-09-13T00:03:22", "description": "Welcome to the first edition of the Qualys Research Team\u2019s \u201cThreat Research Thursday\u201d where we collect and curate notable new tools, techniques, procedures, threat intelligence, cybersecurity news, malware attacks, and more.

This open-source repository tool that we\u2019ve evaluated will help you scan JSON formatted SBOM files to point out any vulnerabilities they may have. [Check out Bomber](<https://github.com/devops-kung-fu/bomber>). \n\n**Alan C2 Framework:** Until recently, this command & control (C2) framework \u2013 even though it was hosted on GitHub \u2013 was closed source. You could download it and test it for free, but not inspect its source code unless you decompiled it. Now the source code has been made available. For example, you can now look at the [certificate information](<https://github.com/enkomio/AlanFramework/blob/8134494037435c5e6478409447efe41f563e0688/src/client/mbedtls/tests/data_files/dir-maxpath/c20.pem>) and add it to your detection pipeline if you have not already done so. [Access the Alan C2 Framework source code](<https://github.com/enkomio/AlanFramework>). \n\n**FISSURE**: This interesting Radio Frequency (RF) framework was released as open source at the recently concluded DEFCONference. With this reverse engineering RF framework, you can detect, classify signals, execute attacks, discover protocols, and analyze vulnerabilities. A lot can be done with this tool! [Check out FISSURE](<https://github.com/ainfosec/FISSURE>). \n\n**Sub7 Legacy**: The source code to your favorite trojan from the not-so-recent past is now available. Well, not really. This is a complete remake of the trojan from the early 2000\u2019s. The look & feel is still the same \u2013 minus the malicious features, but it does make one nostalgic. Here\u2019s hoping that threat actor groups don\u2019t use this Delphi source code for new and nefarious use cases! [Check out the new Sub7 Legacy](<https://github.com/DarkCoderSc/SubSeven>). \n\n**Hashview**: What do you do when you dump a hash via Mimikatz and want to crack it? In a team engagement, a tool like Hashview can help. It allows you to automate hashcat, retroactively crack hashes, and get notifications on a particular event.
