CVE-2025-63432
📋 TL;DR
The Xtooltech Xtool AnyScan Android application fails to validate TLS certificates, allowing attackers on the same network to perform man-in-the-middle attacks. This vulnerability enables interception, decryption, and modification of traffic between the app and its update server, potentially leading to remote code execution. All users of Xtool AnyScan Android app version 4.40.40 and earlier are affected.
💻 Affected Systems
- Xtooltech Xtool AnyScan Android Application
📦 What is this software?
Xtool Anyscan by Xtooltech
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution on the Android device, potentially compromising the device and any connected vehicles or systems.
Likely Case
Interception of sensitive data, installation of malicious updates, or credential theft through MITM attacks.
If Mitigated
Limited to network traffic interception if proper network segmentation and certificate pinning are implemented.
🎯 Exploit Status
Exploitation requires attacker to be on the same network as the victim; MITM tools like mitmproxy can be used.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: Yes
