According to its banner, the version of Apache running on the remote host is 2.4.x prior to 2.4.60. It is, therefore, affected by multiple vulnerabilities:

 - Serving WebSocket protocol upgrades over a HTTP/2 connection could result in a Null Pointer dereference, leading to a crash of the server process, degrading performance. (CVE-2024-36387)

 - SSRF in Apache HTTP Server on Windows allows to potentially leak NTML hashes to a malicious server via SSRF and malicious requests or content. (CVE-2024-38472)

 - 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. (CVE-2024-38473)

 - 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 any URL or source disclosure of scripts meant to only to be executed as CGI. (CVE-2024-38474)

 - 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 are permitted to be served by the server but are not intentionally/directly reachable by any URL, resulting in code execution or source code disclosure. (CVE-2024-38475)

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

 - 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. (CVE-2024-38477)

 - 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. (CVE-2024-39573)

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

An update of the httpd package has been released.

The version of Apache httpd installed on the remote host is prior to 2.4.60. It is, therefore, affected by multiple vulnerabilities as referenced in the 2.4.60 advisory.

  - Serving WebSocket protocol upgrades over a HTTP/2 connection could result in a Null Pointer dereference,     leading to a crash of the server process, degrading performance. (CVE-2024-36387)

  - SSRF in Apache HTTP Server on Windows allows to potentially leak NTML hashes to a malicious server via     SSRF and malicious requests or content Users are recommended to upgrade to version 2.4.60 which fixes this     issue. Note: Existing configurations that access UNC paths will have to configure new directive UNCList     to allow access during request processing. (CVE-2024-38472)

  - 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. (CVE-2024-38473)

  - 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 any URL 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-2024-38474)

  - 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 are permitted to be served by the server but are not     intentionally/directly reachable by any URL, resulting in code execution or source code disclosure.
    Substitutions in server 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.

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

The version of httpd installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-38472 advisory.

The version of httpd installed on the remote host is prior to 2.4.60. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2024-184-01 advisory.

    New httpd packages are available for Slackware 15.0 and -current to fix security issues.

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

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

According to its self-reported version, the Tenable Security Center running on the remote host is 6.2.1, 6.3.0 or 6.4.0.
It is, therefore, affected by multiple vulnerabilities as referenced in the TNS-2024-13 advisory.

  - Security Center leverages third-party software to help provide underlying functionality. Several of the     third-party components (Apache, libcurl) were found to contain vulnerabilities, and updated versions have     been made available by the providers.Out of caution and in line with best practice, Tenable has opted to     upgrade these components to address the potential impact of the issues. Security Center Patch SC-202408.1     updates Apache to version 2.4.62 and libcurl to version 8.8.0 to address the identified vulnerabilities.
    Tenable has released Security Center Patch SC-202408.1 to address these issues. The installation files can     be obtained from the Tenable Downloads Portal: https://www.tenable.com/downloads/security-center     (CVE-2024-2004, CVE-2024-2379, CVE-2024-2398, CVE-2024-2466, CVE-2024-36387, CVE-2024-38472,     CVE-2024-38473, CVE-2024-38474, CVE-2024-38475, CVE-2024-38476, CVE-2024-38477, CVE-2024-39573,     CVE-2024-39884, CVE-2024-40725, CVE-2024-40898, CVE-2024-6197, CVE-2024-6874)
