Description

AI Translation Available

An Improper Check for Unusual or Exceptional Conditions vulnerability in the chassis control daemon (chassisd) of Juniper Networks Junos OS on SRX1500, SRX4100, SRX4200 and SRX4600 allows a local attacker with low privileges to cause a complete Denial of Service (DoS).

When a specific 'show chassis' CLI command is executed, chassisd crashes and restarts which causes a momentary impact to all traffic until all modules are online again.

This issue affects Junos OS on SRX1500, SRX4100, SRX4200 and SRX4600: 

* 23.2 versions before 23.2R2-S6,
* 23.4 versions before 23.4R2-S7
* 24.2 versions before 24.2R2-S2,
* 24.4 versions before 24.4R2,
* 25.2 versions before 25.2R1-S1, 25.2R2.
