XSS attacks generally target the client-side session of a user by injecting scripts into a trusted application's context. This vulnerability potentially allows an attacker to steal session cookies, capture user input, or perform actions on behalf of the authenticated user within the AusweisApp2 interface. The risk is considered low, but users are advised to monitor for updates from Governikus to address this security flaw.

Impact

Successful exploitation could allow unauthorized script execution within the context of the AusweisApp2 application on a victim's machine. This may lead to the compromise of user-specific data managed by the application or unauthorized interaction with the identity services the software facilitates. No specific victim statistics or active exploitation reports are provided in the source documentation.

Recommendation

  1. Monitor official Governikus update channels for patches addressing this XSS vulnerability in AusweisApp2.
  2. Ensure the application is updated to the latest available version once a fix is released.
  3. Restrict execution of untrusted external content or links while the application is active if possible.
