CVE-2025-25211Network attack vector

Unauthorized login via brute-forceable password policy

Published Mar 31, 2025 · Updated Mar 31, 2025

Weak password requirements in CHOCO TEI WATCHER mini all versions allow remote attackers to brute-force credentials and log in. The password-protected CHOCO TEI VIEWER web interface accepts passwords under requirements too weak to resist online guessing; the exact missing constraints are undisclosed. Network reachability to the device is sufficient, with no prior authentication or user interaction, and successful guessing grants access to live video, recordings, and device settings.
