description

Cisco UCS Central Software's web-based management interface is affected by an input-validation flaw associated with path traversal. A remote user with valid credentials may execute commands, write files, or access sensitive information on the device.

mitigation

Apply Cisco's available software updates for UCS Central Software; the supplied evidence does not identify a fixed version. Until updates are deployed, restrict management-interface access to trusted administrators and review privileged account access.
