Description

A vulnerability has been identified in Teamcenter V2412 (All versions < V2412.0013), Teamcenter V2506 (All versions < V2506.0010), Teamcenter V2512 (All versions < V2512.2607), Teamcenter V2606 (All versions < V2606.2607). Affected applications do not properly encode user-supplied input reflected into HTML attribute contexts within the authentication redirect flow (/auth/ endpoint). This could allow an unauthenticated remote attacker to inject arbitrary JavaScript into the browser of an authenticated user who loads a crafted URL, enabling the attacker to perform actions within the victim's Teamcenter session.
