Description
Combodo iTop 3.1.0 through 3.3.0 contains a missing authorization vulnerability in LinkSetController.php that allows authenticated console users to bypass profile grants by supplying arbitrary class and key parameters. Attackers can invoke the linkset delete, detach and get-remote-object routes to delete objects, clear external keys, and read object attributes without permission.
