Junos OS: app-id Signature Update MitM (JSA10952)

high Nessus Plugin ID 130469

Language:

Synopsis

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

Description

According to its self-reported version number, the remote Juniper Junos device is affected by a weakness in the Application Identification (app-id) signature update client. This allows an unauthenticated, remote attacker to perform a Man-in-the-Middle (MitM) attack which can compromise the integrity and confidentiality of the device.

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 JSA10952.
