The remote Ubuntu 18.04 LTS / 20.04 LTS / 21.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5333-1 advisory.
A carefully crafted request body can cause a read to a random memory area which could cause the process to crash. This issue affects Apache HTTP Server 2.4.52 and earlier. (CVE-2022-22719)
Apache HTTP Server 2.4.52 and earlier fails to close inbound connection when errors are encountered discarding the request body, exposing the server to HTTP Request Smuggling (CVE-2022-22720)
If LimitXMLRequestBody is set to allow request bodies larger than 350MB (defaults to 1M) on 32 bit systems an integer overflow happens which later causes out of bounds writes. This issue affects Apache HTTP Server 2.4.52 and earlier. (CVE-2022-22721)
Out-of-bounds Write vulnerability in mod_sed of Apache HTTP Server allows an attacker to overwrite heap memory with possibly attacker provided data. This issue affects Apache HTTP Server 2.4 version 2.4.52 and prior versions. (CVE-2022-23943)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
