Last modified Jun 17, 2026

CVE-2024-39541 is a high-severity vulnerability rated 7.1/10 on the CVSS scale. An Improper Handling of Exceptional Conditions vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause a Denial-of-Service (DoS). When conflicting information (IP or ISO addresses) about a node is added to the Traffic Engineering (TE) database and then a subsequent operation attempts to process these, rpd will crash and restart. This issue affects: Junos OS: * 22.4 versions before 22.4R3-S1, * 23.2 versions before 23.2R2, * 23.4 versions before 23.4R1-S1, 23.4R2, This issue does not affect Junos OS versions earlier than 22.4R1. Junos OS Evolved: * 22.4-EVO versions before 22.4R3-S2-EVO, * 23.2-EVO versions before 23.2R2-EVO, * 23.4-EVO versions before 23.4R1-S1-EVO, 23.4R2-EVO, This issue does not affect Junos OS Evolved versions earlier than before 22.4R1.. EPSS estimates a 0.33% chance of exploitation in the next 30 days.
