Cisco has addressed quite a few vulnerabilities in its Nexus Dashboard. Exploiting these vulnerabilities may permit attackers to conduct CSRF assaults or execute arbitrary code.
Cisco Nexus Dashboard Vulnerabilities
Elaborating on the safety points in a current advisory, Cisco has confirmed patching three totally different vulnerabilities within the Nexus Dashboard.
Cisco’s Nexus Dashboard is a devoted cloud community dashboard enabling customers to observe and handle the whole information middle infrastructure operations. Sadly, these essential functionalities additionally imply that any safety flaws affecting this software would instantly threat the safety of the related community.
Describing the influence of those vulnerabilities, the advisory reads,
Cisco Nexus Dashboard is deployed as a cluster, connecting every service node to 2 networks:
-Knowledge community (fabric0, fabric1)
-Administration community (mgmt0, mgmt1)
The scope of those exploits could be restricted to the community interfaces which have publicity.
Particularly, Cisco has addressed the next three vulnerabilities within the software.
