CVE-2025-30655

Junos OS and Junos OS Evolved: A specific CLI command will cause an RPD crash when rib-sharding and update-threading is enabled



Description

An Improper Check for Unusual or Exceptional Conditions vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a local, low-privileged attacker to cause a Denial-of-Service (DoS). When a specific "show bgp neighbor" CLI command is run, the rpd cpu utilization rises and eventually causes a crash and restart. Repeated use of this command will cause a sustained DoS condition.  The device is only affected if BGP RIB sharding and update-threading is enabled. This issue affects Junos OS:  * All versions before 21.2R3-S9,  * from 21.4 before 21.4R3-S8, * from 22.2 before 22.2R3-S6,  * from 22.4 before 22.4R3-S2,  * from 23.2 before 23.2R2-S3,  * from 23.4 before 23.4R2. and Junos OS Evolved:  * All versions before 21.2R3-S9-EVO,  * from 21.4-EVO before 21.4R3-S8-EVO,  * from 22.2-EVO before 22.2R3-S6-EVO,  * from 22.4-EVO before 22.4R3-S2-EVO,  * from 23.2-EVO before 23.2R2-S3-EVO,  * from 23.4-EVO before 23.4R2-EVO.
