CVE-2025-30652 Information

Description

An Improper Handling of Exceptional Conditions vulnerability in routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a local low-privileged attacker executing a CLI command to cause a Denial of Service (DoS).

When asregex-optimized is configured and a specific \show route as-path\ CLI command is executed the rpd crashes and restarts. Repeated execution of this command will cause a sustained DoS condition. This issue affects Junos OS:

All versions before 21.2R3-S9 
from 21.4 before 21.4R3-S10 
from 22.2 before 22.2R3-S6 
from 22.4 before 22.4R3-S6 
from 23.2 before 23.2R2-S3 
from 23.4 before 23.4R2-S4 
from 24.2 before 24.2R2.

and Junos OS Evolved: All versions before 21.2R3-S9-EVO from 21.4-EVO before 21.4R3-S10-EVO from 22.2-EVO before 22.2R3-S6-EVO from 22.4-EVO before 22.4R3-S6-EVO from 23.2-EVO before 23.2R2-S3-EVO from 23.4-EVO before 23.4R2-S4-EVO from 24.2-EVO before 24.2R2-EVO.
