CVE-2025-63433 — Xtooltech Xtool AnyScan Android Application 4.40.40 and prior uses a hardcoded cryptographic key and IV to decrypt update metadata
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.

Matched remediation archetype
Authentication bypass and missing authentication
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Map every affected endpoint and protocol path, including alternate ports, legacy routes, recovery flows, service accounts, and machine-to-machine access.
- Confirm which deployments enable the affected authentication mode and whether the interface is reachable from untrusted networks.
- Review session, token, credential, and proxy trust configuration without attempting account takeover.
Remediate safely
- Apply the supported fix and centralize fail-closed authentication before protected request handling.
- Remove default or embedded credentials, rotate affected secrets and sessions, and bind authentication decisions to the intended audience and channel.
- Add negative tests for alternate routes, malformed or absent credentials, recovery flows, and proxy-derived identity.
