| 描述 | During security testing of the delete-forum.php endpoint, an HTTP header injection vulnerability was identified. The application takes user-supplied input from the page parameter and unsafely concatenates it into the Location HTTP response header without proper validation, sanitization, or encoding.
By injecting CR (Carriage Return, %0d) and LF (Line Feed, %0a) characters into the page parameter, an attacker can manipulate the HTTP response structure. The vulnerability is triggered when the application performs a redirect via the header() function after certain conditions are met.
Example malicious request:
GET /includes/delete-forum.php?id=1&page=forum%0d%0aSet-Cookie:%20session=Hijacked%0d%0aX-IGNORE: HTTP/1.1
Host: target.com
Cookie: PHPSESSID=valid_session |
