Summary
Stored Cross-Site Scripting (XSS) in Stel Order v3.25.1 and earlier, located at the ‘/app/FrontController’ endpoint via the ‘legalName’ and ‘employeeID’ parameters. The lack of proper input sanitization allows an attacker to inject malicious code that is persistently stored in the database. When other users or administrators access the affected sections, the code executes in their browsers, enabling the theft of session cookies and account hijacking.
