An authenticated attacker could encrypt files, preserving the first four bytes and preventing this particular method from triggering. The affected product implements additional integrity-based detection mechanisms capable of identifying file corruption or encryption for some common file extensions independent of header bytes. As a result, this vulnerability does not represent a complete bypass of ransomware detection, but a limitation of one detection method when evaluated independently. 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. BullWall plans to improve detection method documentation.",

CVE-2025-62000 (GCVE-0-2025-62000)

Vulnerability from cvelistv5 – Published: 2025-12-18 20:32 – Updated: 2026-01-15 19:50

Title

BullWall Ransomware Containment incomplete file inspection

Summary

BullWall Ransomware Containment may not always detect an encrypted file. This issue affects a specific file inspection method that evaluates file content based on header bytes. An authenticated attacker could encrypt files, preserving the first four bytes and preventing this particular method from triggering. The affected product implements additional integrity-based detection mechanisms capable of identifying file corruption or encryption for some common file extensions independent of header bytes. As a result, this vulnerability does not represent a complete bypass of ransomware detection, but a limitation of one detection method when evaluated independently. 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. BullWall plans to improve detection method documentation.

CVE-2025-62001 (GCVE-0-2025-62001)

Vulnerability from cvelistv5 – Published: 2025-12-18 20:32 – Updated: 2026-01-15 19:51

Title

BullWall Ransomware Containment hard-coded folder exclusions

Summary

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.

CVE-2025-62002 (GCVE-0-2025-62002)

Vulnerability from cvelistv5 – Published: 2025-12-18 20:33 – Updated: 2026-01-15 19:51

Title

BullWall Ransomware Containment file count detection bypass

Summary

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.

Vulnerability from cvelistv5 – Published: 2025-12-18 20:36 – Updated: 2026-01-15 19:51

Title

BullWall Server Intrusion Protection (SIP) initialization race condition

Summary

BullWall Server Intrusion Protection (SIP) services are initialized after login services during system startup. A local, authenticated attacker can log in after boot and before SIP MFA is running. The SIP services do not retroactively enforce MFA or disconnect sessions that were not subject to SIP MFA. Versions 4.6.0.0, 4.6.0.6, 4.6.0.7, and 4.6.1.4 are affected. Other versions mayy also be affected. BullWall plans to improve detection method documentation.
