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.
    (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. Users are recommended to upgrade to version 2.4.60, which fixes this issue. (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. Users are recommended to upgrade to version 2.4.60, which fixes this     issue. (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. Users are recommended to upgrade to     version 2.4.60, which fixes this issue. (CVE-2024-39573)

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

The remote host is affected by the vulnerability described in GLSA-202409-31 (Apache HTTPD: Multiple Vulnerabilities)

    Multiple vulnerabilities have been discovered in Apache HTTPD. Please review the CVE identifiers     referenced below for details.

Tenable has extracted the preceding description block directly from the Gentoo 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.

The remote NewStart CGSL host, running version MAIN 7.02, has httpd packages installed that are affected by multiple vulnerabilities:

  - 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. Users are recommended to upgrade to version 2.4.60, which fixes this issue. (CVE-2024-38476)

  - Out-of-bounds Read vulnerability in mod_macro of Apache HTTP Server.This issue affects Apache HTTP Server:
    through 2.4.57. (CVE-2023-31122)

  - An attacker, opening a HTTP/2 connection with an initial window size of 0, was able to block handling of     that connection indefinitely in Apache HTTP Server. This could be used to exhaust worker resources in the     server, similar to the well known slow loris attack pattern. This has been fixed in version 2.4.58, so     that such connection are terminated properly after the configured connection timeout. This issue affects     Apache HTTP Server: from 2.4.55 through 2.4.57. Users are recommended to upgrade to version 2.4.58, which     fixes the issue. (CVE-2023-43622)

  - When a HTTP/2 stream was reset (RST frame) by a client, there was a time window were the request's memory     resources were not reclaimed immediately. Instead, de-allocation was deferred to connection close. A     client could send new requests and resets, keeping the connection busy and open and causing the memory     footprint to keep on growing. On connection close, all resources were reclaimed, but the process might run     out of memory before that. This was found by the reporter during testing of CVE-2023-44487 (HTTP/2 Rapid     Reset Exploit) with their own test client. During normal HTTP/2 use, the probability to hit this bug is     very low. The kept memory would not become noticeable before the connection closes or times out. Users are     recommended to upgrade to version 2.4.58, which fixes the issue. (CVE-2023-45802)

  - 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)

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