Technical details
The vulnerability is a PHP object injection flaw in iTop's user preference functionality that occurs prior to version 3.2.3. It requires network access and an authenticated user account (low privilege level), with user interaction required to trigger the exploit. An attacker with valid credentials can craft malicious serialized PHP objects that, when deserialized during preference processing, execute arbitrary code on the server. This leads to remote code execution with the privileges of the web server process. The issue has been patched in versions 3.2.3 and 3.3.0.
