CVE-2011-10013Public exploitNetwork attack vector

Unauthenticated PHP code execution via incomplete redirect

Published Aug 13, 2025 · Updated Jul 31, 2026

Code injection in Traq 2.0 through 2.3 allows remote attackers to execute arbitrary PHP code through the administrative plugin interface. The authenticate() function in admincp/common.php redirects nonadministrators with header() but does not terminate execution, leaving plugins.php reachable to create a hook containing attacker-supplied PHP. Authentication is not required, and executing the created hook runs attacker-controlled code with the web application's privileges.
