Description
ATutor is vulnerable to Stored Cross Site Scripting in registration functionality. An attacker can register a new account and enter a JavaScript payload in the phone field during registration. When any authenticated user visits the attacker's public profile, the profile template echoes the phone value without output encoding and the browser executes the payload leading to the theft of user's session cookie.
Product is no longer actively supported and the vulnerabilities have not been fixed. Only version 2.2.4 was tested and confirmed as vulnerable, other versions were not tested but might also be vulnerable.
