Server-Side Request Forgery (SSRF) in Apache HTTP Server - CVE-2024-43204
Published: July 10, 2025 / Updated: July 10, 2025
Vulnerability details
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input in mod_proxy . A remote attacker can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.
Note, the vulnerability exploitation 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.
