Xtooltech Xtool AnyScan Android Application 4.40.40 is Missing Authentication for Critical Function. The server-side endpoint responsible for serving update packages for the application does not require any authentication. This allows an unauthenticated remote attacker to freely download official update packages..

The update mechanism in Xtooltech Xtool AnyScan Android Application 4.40.40 and prior is insecure. The application downloads and extracts update packages containing executable code without performing a cryptographic integrity or authenticity check on their contents. An attacker who can control the update metadata can serve a malicious package, which the application will accept, extract, and later execute, leading to arbitrary code execution.

Xtooltech Xtool AnyScan Android Application 4.40.40 and prior uses a hardcoded cryptographic key and IV to decrypt update metadata. The key is stored as a static value within the application's code. An attacker with the ability to intercept network traffic can use this hardcoded key to decrypt, modify, and re-encrypt the update manifest, allowing them to direct the application to download a malicious update package.

Xtooltech Xtool AnyScan Android Application 4.40.40 and prior is Missing SSL Certificate Validation. The application fails to properly validate the TLS certificate from its update server. An attacker on the same network can exploit this vulnerability by performing a Man-in-the-Middle (MITM) attack to intercept, decrypt, and modify traffic between the application and the update server. This serves as the basis for further attacks, including Remote Code Execution.
