Executive brief
Yot CMS is a content management system used to build and manage websites. A vulnerability in its login mechanism allows attackers to inject malicious SQL code through cookie values, potentially enabling them to forge administrator sessions and gain unauthorized administrative access to the website without proper credentials.
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.
