Routine

HIGH 8.8DOWNGRADE

CVE-2025-62001 is a high-severity flaw (CVSS 8.8) affecting ransomware containment. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

BullWall Ransomware Containment supports configurable file and directory exclusions such as '$RECYCLE.BIN' to balance monitoring scope and performance. Certain exclusion patterns could allow an authenticated attacker to rename directories in a way that avoids monitoring. Fixed in 4.6.1.14 and 5.0.0.42, which remove hardcoded exclusion behavior and exposes exclusion handling as configurable settings.
