These vulnerabilities expose core enterprise infrastructure — servers, security appliances, network devices, and collaboration systems — to full administrative takeover by any attacker who can authenticate to the IMC interface with even the lowest privilege level. A successful exploit could allow an attacker to disable security controls, exfiltrate data, or disrupt operations across a broad swath of Cisco-based infrastructure simultaneously. Organizations running Cisco UCS-based platforms in regulated industries face compounded risk: infrastructure downtime and potential data exposure could trigger breach notification obligations and operational penalties under applicable compliance frameworks.
You Are Affected If
You operate any Cisco UCS C-Series M5 or M6, E-Series M3 or M6, or S-Series storage server with IMC enabled
You run Cisco-built security or network appliances on UCS hardware: Secure Firewall Management Center, Secure Endpoint Private Cloud, Secure Malware Analytics, Secure Network Analytics, Nexus Dashboard, Catalyst Center, HyperFlex nodes, Catalyst 8300 Edge uCPE, or 5000 Series ENCS
The IMC web management interface is reachable from any network segment other than a dedicated out-of-band management network
Read-only or low-privileged IMC accounts are provisioned for monitoring, helpdesk, or third-party vendor access
You have not yet applied the patches specified in Cisco PSIRT advisory cisco-sa-cimc-cmd-inj-3hKN3bVt
Board Talking Points
A vulnerability in Cisco's hardware management interface allows an attacker with basic login credentials to take full control of more than 20 types of enterprise systems, including servers, firewalls, and network appliances.
IT and security teams should apply Cisco-supplied patches across all affected platforms within the next patch cycle, with internet-exposed systems prioritized for immediate action.
Without patching, any attacker who gains even read-only access to these management interfaces — through a compromised account or weak credentials — can fully compromise the underlying infrastructure.
HIPAA — Secure Network Analytics and Secure Endpoint Private Cloud, if compromised, may expose visibility into protected health information traversing monitored networks
PCI-DSS — UCS-based infrastructure hosting or segmenting cardholder data environments; root-level compromise eliminates network segmentation assurances required under PCI-DSS Requirement 1
