Vulnerability Data

An administrator may attempt to block all networks by specifying "\*" or "all" as the network identifier. However, these values are not supported and do not trigger any validation error. Instead, they are silently interpreted as network 0 which results…

Mitigating Controls (NIST 800-53 r5) AI

SC-24 Fail in Known State good match

SC-24 directly requires the system to fail to a known state that preserves security properties, structurally stopping fallback to a less-secure mode.

SI-17 Fail-safe Procedures good match

SI-17 mandates explicit fail-safe procedures that activate on indicated failures, preventing the insecure fallback behavior.

CP-12 Safe Mode good match

CP-12 forces entry into a safe mode on detected conditions, limiting exposure but not covering every failure path.

SA-8 Security and Privacy Engineering Principles partial match

SA-8 requires application of engineering principles that include fail-secure design, reducing the likelihood the weakness is introduced.

PR.PS-06 mostly match
prevents

Secure-development practices explicitly include designing error and failure handling to remain in a secure state.

PR.AA-05 partial match
prevents

Least-privilege policy and enforcement directly counters the permissive-access fallback example in the CWE.

PR.PS-01 partial match
prevents

Hardened baselines and configuration management reduce the chance that error paths default to insecure settings.

A.5.25 Assessment and decision on information security events none match
none

The control forces an explicit evaluation step before any response, reducing the chance that a failure condition will default to an unsafe open state.
