The version of httpd installed on the remote host is prior to 2.4.61-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2024-2594 advisory.

    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 indirectories 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)

    A regression in the core of Apache HTTP Server 2.4.60 ignores some use of the legacy content-type based     configuration of handlers.   AddType and similar configuration, under some circumstances where files are     requested indirectly, result in source code disclosure of local content. For example, PHP scripts may be     served instead of interpreted.

    Users are recommended to upgrade to version 2.4.61, which fixes this issue. (CVE-2024-39884)

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

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