CVE-2017-10619

High
Published: Translated: NVD NIST

Summary

CVE-2017-10619 affects Juniper Networks SRX1400, SRX3400, SRX3600, SRX5400, SRX5600, and SRX5800 devices when configured in high availability cluster mode with Express Path enabled. Certain multicast packets may cause the flowd process to crash, interrupting traffic and triggering fail-over to the secondary node.

Risk Assessment

Repeated crashes of the flowd process may lead to an extended denial of service condition, impacting network availability and potentially disrupting critical applications.

Recommendation

It is recommended to upgrade the Junos OS to versions 12.3X48-D45 or 15.1X49-D80 to mitigate this vulnerability. Additionally, monitor multicast traffic in the network and consider disabling Express Path if it is not necessary.

Original NVD description (English source)

When Express Path (formerly known as service offloading) is configured on Juniper Networks SRX1400, SRX3400, SRX3600, SRX5400, SRX5600, SRX5800 in high availability cluster configuration mode, certain multicast packets might cause the flowd process to crash, halting or interrupting traffic from flowing through the device and triggering RG1+ (data-plane) fail-over to the secondary node. Repeated crashes of the flowd process may constitute an extended denial of service condition. This service is not enabled by default and is only supported in high-end SRX platforms. Affected releases are Juniper Networks Junos OS 12.3X48 prior to 12.3X48-D45, 15.1X49 prior to 15.1X49-D80 on SRX1400, SRX3400, SRX3600, SRX5400, SRX5600, SRX5800.
