## Technical details

The vulnerability is a SQL injection flaw in the Login function of the global.php file, specifically in the Cookie Handler component. The attack manipulates the yot3_user and yot3_pass cookie arguments by injecting SQL syntax, which are processed without proper sanitization. The attack is network-accessible and requires no authentication, as it exploits the cookie-based auto-login mechanism. A successful exploit allows an attacker to bypass authentication and create forged administrator sessions. Patches are expected to address input validation in the cookie handler.
