1) Out-of-bounds read

EUVDB-ID: #VU64083

Risk: Low

CVSSv3.1: 3.5 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-28615

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

Exploit availability: No

Description

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().

Mitigation

Install update from vendor's website.
