CVE-2025-63434: The update mechanism in Xtooltech Xtool AnyScan Android Application 4.40.40 and prior is insecure
CVE-2025-63434 is a high-severity flaw (CVSS 8.8) affecting xtool anyscan. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
Why this priority
- High severity
- Public exploit reference
A fixed release or distro patch exists.
