Junos OS: Established BGP Session Termination Vulnerability (JSA10996)

high Nessus Plugin ID 136119

Language:

Synopsis

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

Description

The version of Junos OS installed on the remote host is 12.3, 12.3X48, 14.1X53 or prior to 15.1R7-S5, 15.1F6-S13, 15.1X49-D180, 15.1X53-D238, 15.1X53-D497, 15.1X53-D592, 16.1R7-S7, 17.1R2-S12, 17.2R2-S7, 17.2X75-D102, 17.3R2-S5, 17.4R1-S8, 18.1R2-S4, or 18.2X75-D20. It is, therefore, affected by a vulnerability in the BGP FlowSpec implementation. An unauthenticated, remote attacker can exploit, specific BGP FlowSpec advertisement, in order to terminate an established BGP session as referenced in the JSA10996 advisory.

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 JSA10996
