Junos OS routing protocol daemon (RPD) process may crash and restart or may lead to remote code execution while processing specific BGP NOTIFICATION messages. By continuously sending crafted BGP NOTIFICATION messages, an attacker can repeatedly crash the RPD process causing a sustained Denial of Service. Due to design improvements, this issue does not affect Junos OS 16.1R1, and all subsequent releases. This issue only affects the receiving BGP device and is non-transitive in nature. Affected releases are Juniper Networks Junos OS: 15.1F5 versions starting from 15.1F5-S7 and all subsequent releases; 15.1F6 versions starting from 15.1F6-S3 and later releases prior to 15.1F6-S10; 15.1F7 versions 15.1 versions starting from 15.1R5 and later releases, including the Service Releases based on 15.1R5 and on 15.1R6 prior to 15.1R6-S6 and 15.1R7;

Detection & IOCs extracted from sources · hover to see the quote

• → Detect repeated BGP NOTIFICATION messages sent to a Junos OS device running RPD, which may indicate exploitation attempts causing RPD crash/restart cycles ↗
• → Monitor the RPD (routing protocol daemon) process on Junos OS for unexpected crashes and restarts, particularly when BGP NOTIFICATION messages are being received ↗
• → This vulnerability is non-transitive and only affects the directly receiving BGP device; focus monitoring on BGP peers receiving NOTIFICATION messages rather than transit nodes ↗

• · Vulnerability does NOT affect Junos OS 16.1R1 and all subsequent releases due to design improvements; ensure devices are patched to 16.1R1 or later ↗
• · Affected versions include Junos OS 15.1F5 from 15.1F5-S7 onward, 15.1F6 from 15.1F6-S3 up to (but not including) 15.1F6-S10, 15.1F7, and 15.1R from 15.1R5 onward including service releases on 15.1R5 and 15.1R6 prior to 15.1R6-S6 and 15.1R7 ↗
