The Cisco Nexus Dashboard 1.1 version and subsequent versions are affected by the three vulnerabilities that were discovered during the ongoing internal security testing of Cisco Nexus Dashboards. Dashboard version 2.2(1e) has been released with fixes and improvements for the issues that have been reported.

No exploitation has been reported

It would be possible for the malicious images to be executed whenever a device or pod was rebooted or restarted. During internal security testing conducted by Cisco’s ASIG, security researchers found these vulnerabilities and reported them.

In response to a question from the PSIRT of Cisco, the company has confirmed that it is not aware of any exploits in the wild that are publicly available.

It is possible that the attacker may also be able to view sensitive information if the exploit is successful, such as the administrator credentials for the affected controllers.

As a side note, Cisco also released patches for 10 security flaws a little over two weeks after releasing the initial updates.
