CVE-2025-62001 is a high-severity Unprotected Alternate Channel (CWE-420) vulnerability in Bullwall Ransomware Containment. Its CVSS base score is 8.7 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Fallback Channels (T1008); ranked at the 27th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SC-8 (Transmission Confidentiality and Integrity) and AC-4 (Information Flow Enforcement) — see the control section below for these in your framework.

Vulnerability Data
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,…

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Transmission confidentiality and integrity requirements apply to all transmitted data, preventing weaker protection on secondary channels.
Information flow enforcement requires consistent authorization and control over every path, directly stopping unequal protection of alternate channels.
Boundary protection mandates monitoring and control at all external and key internal interfaces, eliminating unprotected alternate channels.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Protecting all data-in-transit directly mitigates unequal channel protection though the control addresses broader transit scenarios.
Network protection from unauthorized access inherently requires securing every channel, not just primaries.
Network monitoring can surface use of unprotected alternate channels but does not prevent the design flaw.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Access restrictions may cover primary paths but leave alternate channels unprotected unless explicitly extended.
Secure authentication applies to primary channels but does not ensure alternate channels receive the same strength.
Network security controls ensure all channels receive equivalent protection, directly addressing unprotected alternate channels.
Security of network services requires consistent protection across all service channels, mitigating alternate-channel weaknesses.
Network segregation can reduce exposure of alternate channels but does not guarantee equivalent protection levels.
Cryptography can protect alternate channels but does not address the policy of applying equal protection across channels.
