CyberRota Analysis
AI-GeneratedAn improper check for unusual conditions in the routing protocol daemon (RPD) of Juniper Networks' Junos OS and Junos OS Evolved allows unauthenticated adjacent attackers to trigger a Denial-of-Service (DoS) by sending a malformed BGP update, resulting in RPD crashes and service outages until routing reconvergence occurs. This vulnerability impacts Junos OS versions 25.2 prior to 25.2R2 and Junos OS Evolved versions 25.2 prior to 25.2R2-EVO. Organizations using these affected versions should prioritize remediation to prevent potential service disruptions.
Original NVD 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 an adjacent, unauthenticated attacker sending a specific BGP update over an established BGP session to cause a Denial-of-Service (DoS). Upon receipt of a specifically malformed non-inet/inet6 unicast BGP update, an RPD crash and restart is triggered, which will cause a complete service outage until routing has reconverged. The rpd crash occurs before the update can be readvertised, so there is no downstream propagation. This issue affects: * Junos OS versions 25.2 before 25.2R2; * Junos OS Evolved versions 25.2 before 25.2R2-EVO. This issue doesn't affect Junos OS versions before 25.2R1 nor Junos OS Evolved versions before 25.2R1-EVO.
