MEDIUM 4.3DOWNGRADE

CVE-2025-62002 is a medium-severity flaw (CVSS 4.3) affecting ransomware containment. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

BullWall Ransomware Containment considers the number of files modified to trigger detection. An authenticated attacker could encrypt a single (possibly large) file without triggering detection if thresholds are configured to require multiple file changes. The number of files to trigger detection can be configured by the user. Versions 4.6.0.0, 4.6.0.6, 4.6.0.7, and 4.6.1.4 are affected. Other versions may also be affected.
