Last Modified: Oct 15, 2025

Opened: May 14, 2025

Severity: 2-Critical

Symptoms

The nodejs services using default f5-irule.crt certificate request template gets validity upto jul 2027 and may fail to work after July 2027. Haven't provided any access to use these certificates in other Node.js services, although they could logically be used.

Impact

NodeJS/iRules services using unmodified f5-irule.crt fails to work after July 2027.

Conditions

BIG-IP software version 17.x using nodeJS/iRules beyond July 2027 without modifying f5-irule.crt validity period.

Workaround

None
