The remote AlmaLinux 8 host has packages installed that are affected by a vulnerability as referenced in the ALSA-2024:5193 advisory.

    * httpd: Security issues via?backend applications whose response headers are malicious or exploitable     (CVE-2024-38476)

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

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

According to the versions of the httpd packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    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)

    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)

    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-2024-38474)

    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 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-2024-38475)

    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)

    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-2024-38476)

    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)
