Description

This security bulletin contains information about 1 vulnerability.


1) Out-of-bounds read (CVE-ID: CVE-2022-28615)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the ap_strcmp_match() function when processing an extremely large input buffer. A remote attacker can send a specially crafted HTTP request to the web server, trigger an out-of-bounds read error and read contents of memory on the system.

Note, the code distributed with the Apache HTTP Server cannot be coerced into such a call. The vulnerability can affect third-party modules or lua scripts that use ap_strcmp_match().
