Detailsinfo

A vulnerability was found in Cisco Digital Network Architecture Center. It has been classified as critical. Affected is an unknown part of the component SSH Host Key Handler. The manipulation with an unknown input leads to a hard-coded key vulnerability. CWE is classifying the issue as CWE-321. The use of a hard-coded cryptographic key significantly increases the possibility that encrypted data may be recovered. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

A vulnerability in the SSH server of Cisco Catalyst Center, formerly Cisco DNA Center, 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.

The advisory is shared for download at sec.cloudapps.cisco.com. This vulnerability is traded as CVE-2024-20350 since 11/08/2023. The exploitability is told to be difficult. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Successful exploitation requires user interaction by the victim.
