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
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,
