The remote AlmaLinux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2023:0970 advisory.

  - A carefully crafted If: request header can cause a memory read, or write of a single zero byte, in a pool     (heap) memory location beyond the header value sent. This could cause the process to crash. This issue     affects Apache HTTP Server 2.4.54 and earlier. (CVE-2006-20001)

  - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in mod_proxy_ajp of     Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to. This     issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.54 and prior versions.
    (CVE-2022-36760)

  - Prior to Apache HTTP Server 2.4.55, a malicious backend can cause the response headers to be truncated     early, resulting in some headers being incorporated into the response body. If the later headers have any     security purpose, they will not be interpreted by the client. (CVE-2022-37436)

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