Command Injection in Cisco IMC Web-Based Management Interface

Successful exploitation allows a remote authenticated administrator-level attacker to execute arbitrary operating system commands as root on the affected device. This can result in full compromise of the underlying host, including modification of system configuration, deployment of persistence, access to sensitive data, disruption of services, and further post-exploitation activity with the highest local privileges.

No workaround is available according to the provided content. Risk can be reduced by ensuring the Cisco IMC web management interface is not publicly accessible, placing IMC in a separate management network, enforcing strong segmentation and access controls, and restricting administrative access to trusted users and management hosts only.

Cisco has released software updates to address this vulnerability. Affected organizations should upgrade Cisco IMC and any impacted dependent platforms to Cisco-fixed releases as quickly as possible. Supporting content indicates fixed-version guidance is provided by Cisco for affected IMC and NFVIS releases; for example, 5000 Series ENCS running Cisco NFVIS 4.15 and earlier should be upgraded to NFVIS 4.15.5 or later, and Catalyst 8300 Series Edge uCPE running NFVIS 4.18 should be upgraded to 4.18.3 or later, with earlier NFVIS branches migrated to a fixed release as advised by Cisco. Apply the vendor advisory's product-specific fixed version guidance for each affected platform.
