description

Cisco Unified Computing System Central Software's web-based management interface is affected by insufficient validation of HTTP request input. A remote attacker with valid credentials could run commands, modify files, or access sensitive information on an affected device.

Still under analysis: more detail becomes available as the pipeline runs.

mitigation

Apply Cisco's available software updates promptly; no fixed version is specified in the advisory. Until updates are installed, restrict management-interface access to trusted administrative networks and review privileged account access.
