MISP: Authentication failure logging suppressed during Redis unavailability

03 Exploitation and scoring

Exploitation
Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.
SSVC decision
  • ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
  • AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
  • Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.
CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.
EPSS probability
0.53% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 44.7% of scored records. A rank, not a probability.
NVD base score
5.1 (CVSS v4.0), scored by the NVD independently of the CNA.

07 Remediation

The _shouldLog() method now explicitly checks whether the Redis connection is available before attempting to use it. If setupRedis() returns false, the method immediately returns true, causing every authentication-failure event to be logged. This converts the previous fail-closed behavior (silence on dependency failure) into a fail-open behavior for security logging (log everything when the throttle state is unavailable), ensuring that a Redis outage cannot be used to suppress the audit trail of failed authentication attempts.
