The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the d7efc2ad-37af-11ef-b611-84a93843eb75 advisory.

    The Apache httpd project reports:
    DoS by Null pointer in websocket over HTTP/2 (CVE-2024-36387) (Low).
                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.
    Proxy encoding problem (CVE-2024-38473) (Moderate).
                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.
    Weakness with encoded question marks in backreferences                 (CVE-2024-38474) (Important). 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.
    Weakness in mod_rewrite when first segment of substitution matches                 filesystem path (CVE-2024-38475) (Important). 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.
    may use exploitable/malicious backend application output to run local                 handlers via internal redirect (CVE-2024-38476) (Important).
                Vulnerability in core of Apache HTTP Server 2.4.59 and earlier are                 vulnerable to information disclosure, SSRF or local script execution                 via backend applications whose response headers are malicious or                 exploitable.
    Crash resulting in Denial of Service in mod_proxy via a malicious                 request (CVE-2024-38477) (Important). 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.
    mod_rewrite proxy handler substitution (CVE-2024-39573) (Moderate).
                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.

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

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