Juniper Junos OS DoS (JSA69898)

critical Nessus Plugin ID 166332

Language:

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The version of Junos OS installed on the remote host is affected by a DoS vulnerability as referenced in the JSA69898 advisory due to the Improper Handling of an Unexpected Data Type in the processing of EVPN routes on Juniper Networks Junos OS and Junos OS Evolved. An attacker in direct control of a BGP client connected to a route reflector, or via a machine in the middle (MITM) attack, can send a specific EVPN route contained within a BGP Update, triggering a routing protocol daemon (RPD) crash, leading to a Denial of Service (DoS) condition. Continued receipt and processing of these specific EVPN routes could create a sustained Denial of Service (DoS) condition.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Apply the relevant Junos software release referenced in Juniper advisory JSA69898
