Subject: CVE-2024-43204: Apache HTTP Server: SSRF with mod_headers setting
 Content-Type header 

Severity: low 

Affected versions:

- Apache HTTP Server 2.4.0 through 2.4.63

Description:

SSRF in Apache HTTP Server with mod_proxy loaded allows an attacker to send outbound proxy requests to a URL controlled by the attacker.  Requires an unlikely configuration where mod_headers is configured to modify the Content-Type request or response header with a value provided in the HTTP request.

Users are recommended to upgrade to version 2.4.64 which fixes this issue.
