Junos OS: SRX Series: Cluster configuration sync failures occur if the root user account is locked out

When the device is configured to perform account lockout with a defined period of time, any unauthenticated user attempting to log in as root with an incorrect password can trigger a lockout of the root account. When an SRX Series device is in cluster mode, and a cluster sync or failover operation occurs, then there will be errors associated with synch or failover while the root account is locked out. Administrators can confirm if the root account is locked out via the following command root@device> show system login lockout user root User Lockout start Lockout end root 1995-01-01 01:00:01 PDT 1995-11-01 01:31:01 PDT Affected releases are Juniper Networks Junos OS 12.1X46 prior to 12.1X46-D65 on SRX series; 12.3X48 prior to 12.3X48-D45 on SRX series; 15.1X49 prior to 15.1X49-D75 on SRX series.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
