Junos OS Default Credentials Vulnerability (JSA10998)

Critical Nessus Plugin ID 135683

Synopsis

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

Description

The version of Junos OS installed on the remote host is vMX prior to 17.1R2-S11, 17.2R3-S3, 17.3R2-S5, 17.4R2-S9, 18.1R3-S9, 18.2R2-S7, 18.2X75-D420, 18.3R1-S7, 18.4R1-S5, 19.1R1-S4, 19.2R1-S3, or 19.3R1-S1. It is, therefore, affected by a vulnerability which allows an unauthenticated remote attacker to exploit default credentials stored in vMX configuration and access the vMX instance without authorization as referenced in the JSA10998 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 JSA10998
