CVE-2022-22193

rpd crash via unexpected CLI data type

Published Apr 14, 2022 · Updated Sep 17, 2024

Improper data-type handling in rpd in Juniper Networks Junos OS and Junos OS Evolved allows local users to crash the process. With BGP RIB sharding configured, an undisclosed CLI command causes rpd to process an unexpected data type and terminate; Juniper has not disclosed the command or code locus. Low-privileged authenticated CLI access is required, and repeated execution can sustain routing outages and disrupt traffic while rpd restarts.
