Summary

The Xtooltech Xtool AnyScan Android application version 4.40.40 has missing authentication for a critical function. The server-side endpoint responsible for serving update packages does not require any authentication, allowing an unauthenticated remote attacker to freely download official update packages.

Risk Assessment

An unauthenticated attacker can download official update packages, which may facilitate reverse engineering or preparation of attacks on application users. This threatens the confidentiality and integrity of the update distribution process.

Recommendation

Implement authentication and authorization for access to the update server endpoint and consider signing update packages. Update the application to a fixed version when available.
