CVE-2018-0037: Junos OS: RPD daemon crashes due to receipt of crafted BGP NOTIFICATION messages

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;

Security readout for executives and security teams

A crafted BGP NOTIFICATION message can crash Junos OS routing software and may also allow remote code execution. Repeated messages can keep routing disrupted. The issue is critical because exploitation is remote, unauthenticated, and targets network routing infrastructure. Exposure is most likely on Juniper routers running affected Junos OS 15.1 releases with BGP enabled, especially devices receiving BGP traffic from external or less trusted peers. Treat this as urgent for affected BGP infrastructure. A successful attack can disrupt routing and may carry code-execution risk. Patch planning should focus first on internet-facing and business-critical Juniper routers. Mitigation focus: Identify Junos OS 15.1F and 15.1R devices running BGP.; Upgrade affected devices to a Juniper-advised fixed or unaffected release.; Prioritize edge routers with external or less trusted BGP peers..
