Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2023-25690

CWE-ID: CWE-113 - Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting')

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform HTTP splitting attacks.

The vulnerability exists due to software does not correclty process CRLF character sequences in mod_rewrite and mod_proxy. A remote attacker can send specially crafted request containing CRLF sequence and make the application to send a split HTTP response.
