CVE-2025-62002Network attack vector

Authenticated detection bypass via file-count threshold

Published Dec 18, 2025 · Updated Dec 18, 2025

Detection bypass in BullWall Ransomware Containment 4.6.0.0 and later allows remote authenticated users to encrypt one file undetected. The detection logic counts modified files against a configurable threshold rather than treating one file's encryption as sufficient to trigger an alert. Exposure requires valid credentials and a threshold above one file, allowing encryption of one large file without automated detection or containment.
