Low risk26th percentile - higher than 26% of all known CVEs
Summary
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.
Risk Assessment
An attacker can achieve arbitrary code execution on the victim's device, taking control of the application and potentially user data. The risk affects users of vulnerable Xtool AnyScan versions.
Recommendation
Update Xtool AnyScan to a version later than 4.40.40 if the vendor has released a fix. Until updated, avoid installing the app from untrusted sources and limit its permissions.
Other vulnerabilities in Xtool AnyScan
See all- CVE-2025-63433Medium
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 able to intercept network traffic can use this hardcoded key to decrypt, modify, and re-encrypt the update manifest, directing the application to download a malicious update package.
- CVE-2025-63432Medium
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 perform a man-in-the-middle attack to intercept, decrypt, and modify traffic between the application and the update server, serving as the basis for further attacks including remote code execution.
