Vulnerability Details

CVEID:CVE-2021-23358
**DESCRIPTION:**Node.js underscore module could allow a remote attacker to execute arbitrary code on the system, caused by a flaw in the template function. By sending a specially-crafted argument using the variable property, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 9.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/198958 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

CVEID:CVE-2018-3824
**DESCRIPTION:**Elastic X-Pack Machine Learning is vulnerable to cross-site scripting, caused by improper validation of user-supplied input. A remote authenticated attacker could exploit this vulnerability to inject malicious script into a Web page which would be executed in a victim’s Web browser within the security context of the hosting Web site, once the page is viewed. An attacker could use this vulnerability to steal the victim’s cookie-based authentication credentials.
CVSS Base score: 5.4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/150286 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N)

CVEID:CVE-2019-7611
**DESCRIPTION:**Elastic Elasticsearch could allow a remote authenticated attacker to gain elevated privileges on the system, caused by an improper permission issue. By sending a specially-crafted request, an attacker could exploit this vulnerability to gain privileges.
CVSS Base score: 8.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/159335 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)

CVEID:CVE-2021-29425
**DESCRIPTION:**Apache Commons IO could allow a remote attacker to traverse directories on the system, caused by improper input validation by the FileNameUtils.normalize method. An attacker could send a specially-crafted URL request containing “dot dot” sequences (/…/) to view arbitrary files on the system.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/199852 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)

CVEID:CVE-2020-7021
**DESCRIPTION:**Elasticsearch could allow a local authenticated attacker to obtain sensitive information, caused by an error when audit logging and the emit_request_body option is enabled. By opening the audit log, a local authenticated attacker could obtain password hashes or authentication tokens and use this information to launch further attacks against the affected system.
CVSS Base score: 1.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/196943 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:H/UI:N/S:U/C:L/I:N/A:N)

CVEID:CVE-2018-3823
**DESCRIPTION:**Elastic X-Pack Machine Learning is vulnerable to cross-site scripting, caused by improper validation of user-supplied input. A remote authenticated attacker could exploit this vulnerability to inject malicious script into a Web page which would be executed in a victim’s Web browser within the security context of the hosting Web site, once the page is viewed.

CVEID:CVE-2020-7020
**DESCRIPTION:**Elastic Enterprise Search could allow a remote authenticated attacker to obtain sensitive information, caused by not properly preserving security permissions in search queries. By sending a search request, a remote attacker could exploit this vulnerability to disclose the existence of documents.
CVSS Base score: 3.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/190409 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N)

CVEID:CVE-2020-8908
**DESCRIPTION:**Guava could allow a remote authenticated attacker to bypass security restrictions, caused by a temp directory creation vulnerability in com.google.common.io.Files.createTempDir(). By sending a specially-crafted request, an attacker could exploit this vulnerability to bypass access restrictions.

Affected Products and Versions

For earlier and unsupported versions of the products, IBM recommends upgrading to a fixed, supported version of the product.

Remediation/Fixes

The recommended solution is to apply the Interim Fix (iFix) or Cumulative Fix (CF) containing APAR JR64096 as soon as practical:

• IBM Business Automation Workflow (including fix for IBM Business Process Manager V8.6.0.0 2018.03)
• For IBM Business Automation Workflow V18.0, V19.0, and V20.0
  · Upgrade to minimal cumulative fix levels as required by iFix and then apply iFix JR64096
  --OR–
  · Apply cumulative fix Business Automation Workflow V21.0.3 or later

For IBM Business Process Manager V8.6
· Upgrade to minimal cumulative fix levels as required by iFix and then apply iFix JR64096
--OR–
· Upgrade to Business Automation Workflow V21.0.3 or later

The fix removes offline documentation (if installed) as described in

· Downloadable content for IBM Business Process Manager (BPM) documentation (Knowledge Center)
· Downloadable content for IBM Business Automation Workflow documentation (Knowledge Center)
