Apache 2.4.x < 2.4.58 Multiple Vulnerabilities

According to its banner, the version of Apache running on the remote host is 2.4.x prior to 2.4.58. It is, therefore, affected by multiple vulnerabilities:

• Out-of-bounds read vulnerability in mod_macro of Apache HTTP Server. (CVE-2023-31122)

• An attacker, opening a HTTP/2 connection with an initial window size of 0, was able to block handling of that connection indefinitely in Apache HTTP Server. This could be used to exhaust worker resources in the server, similar to the well known slow loris attack pattern. (CVE-2023-43622)

• 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. (CVE-2023-45802) Note that the scanner has not tested for these issues but has instead relied only on the application’s self-reported version number.
