QID 150737: Apache HTTP Server Prior to 2.4.58 Multiple Security Vulnerabilities

The Apache HTTP Server, colloquially called Apache, is a free and open-source cross-platform web server software.

The Apache web server on the remote computer is prior to 2.4.58. . It's running a version older than 2.4.58, which means it could have several security issues mentioned in the 2.4.58 advisory.

CVE-2023-31122 : Out-of-bounds Read vulnerability in mod_macro of Apache HTTP Server
CVE-2023-43622 : DoS in HTTP/2 with initial windows size 0
CVE-2023-45802 : When a HTTP/2 stream was reset (RST frame) by a client, there was a time window were the requests memory resources were not reclaimed immediately. Instead, de-allocation was deferred to connection close. A client could send new requests and resets, keeping the connection busy and open and causing the memory footprint to keep on growing. On connection close, all resources were reclaimed, but the process might run out of memory before that.

Affected Versions:
Apache HTTP Server version from 2.4.0 to 2.4.57

QID Detection Logic (Unauthenticated):
This QID sends a HTTP GET request and checks the response headers to confirm if the host is running vulnerable version of Apache HTTP Server.

Exploitation of the vulnerability could lead to uncontrolled resource consumption or buffer over-read.
