high Nessus Plugin ID 239174

Synopsis

The remote TencentOS Server 4 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:0281 advisory.

Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

CVE-2024-39573:
Potential SSRF in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows an attacker to cause unsafe RewriteRules to unexpectedly setup URL's to be handled by mod_proxy.
Users are recommended to upgrade to version 2.4.60, which fixes this issue.

CVE-2024-38477:
null pointer dereference in mod_proxy in Apache HTTP Server 2.4.59 and earlier allows an attacker to crash the server via a malicious request.
Users are recommended to upgrade to version 2.4.60, which fixes this issue.

CVE-2024-38476:
Vulnerability in core of Apache HTTP Server 2.4.59 and earlier are vulnerably to information disclosure, SSRF or local script execution viabackend applications whose response headers are malicious or exploitable.

Users are recommended to upgrade to version 2.4.60, which fixes this issue.

CVE-2024-38475:
Improper escaping of output in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows an attacker to map URLs to filesystem locations that arepermitted to be served by the server but are not intentionally/directly reachable by any URL, resulting in code execution or source code disclosure.

Substitutions inserver context that use a backreferences or variables as the first segment of the substitution are affected. Some unsafe RewiteRules will be broken by this change and the rewrite flag UnsafePrefixStat can be used to opt back in once ensuring the substitution is appropriately constrained.

CVE-2024-38474:
Substitution encoding issue in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows attacker to execute scripts in directories permitted by the configuration but not directly reachable by anyURL or source disclosure of scripts meant to only to be executed as CGI.

Users are recommended to upgrade to version 2.4.60, which fixes this issue.

Some RewriteRules that capture and substitute unsafely will now fail unless rewrite flag UnsafeAllow3F is specified.

CVE-2024-38473:
Encoding problem in mod_proxy in Apache HTTP Server 2.4.59 and earlier allows request URLs with incorrect encoding to be sent to backend services, potentially bypassing authentication via crafted requests.
Users are recommended to upgrade to version 2.4.60, which fixes this issue.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
