Description

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.

Affected products

BullWall Ransomware Containment: 4.6.0.0, 4.6.0.6, 4.6.0.7, 4.6.1.4
