Cisco Catalyst Center Static SSH Host Key (cisco-sa-dnac-ssh-e4uOdASj)

high Nessus Plugin ID 207806

Synopsis

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

Description

The version of Cisco Catalyst Center (formerly Cisco DNA Center) installed on the remote host is prior to 2.3.5.6, 2.3.6.x, or 2.3.7.x prior to 2.3.7.5. It is, therefore, affected by a vulnerability in the SSH server that could allow an unauthenticated, remote attacker to impersonate a Cisco Catalyst Center appliance. This vulnerability is due to the presence of a static SSH host key. An attacker could exploit this vulnerability by performing a machine-in-the-middle attack on SSH connections, which could allow the attacker to intercept traffic between SSH clients and a Cisco Catalyst Center appliance. A successful exploit could allow the attacker to impersonate the affected appliance, inject commands into the terminal session, and steal valid user credentials.

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

Solution

Upgrade to the relevant fixed version referenced in Cisco bug ID CSCwi40467
