Doc Text:
A Server-side request forgery (SSRF) vulnerability exists in Apache httpd when the server has mod_proxy loaded and is configured with mod_headers to modify the Content-Type header in the HTTP request or response using a value supplied by the user. Under this configuration, this flaw allows an attacker to craft specially crafted requests to manipulate the Content-Type header and trigger outbound requests to arbitrary attacker-controlled URLs via proxy. The vulnerability stems from inadequate input validation and unsafe header manipulation, ultimately allowing an attacker to influence server-side network behavior.

Description OSIDB Bzimport 2025-06-24 12:35:19 UTC
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.
