| Impact | The CVSS 3.1 score of 6.5 (Medium severity) understates the actual risk due to the privileged context required. However, cross-referencing all signals reveals important nuances: the CVSS vector AV:N/AC:L/PR:H/UI:N indicates network-remote attack with high privileges required (admin), low complexity, and no user interaction. While EPSS data is not provided, the exploitation probability is moderate-an attacker must already possess administrative credentials, significantly reducing real-world attack surface compared to unauthenticated vulnerabilities. Cisco explicitly upgraded the Security Impact Rating to High despite the CVSS Medium score, citing additional post-exploitation risks once root access is obtained. No KEV (CISA Known Exploited Vulnerabilities) status or public POC is confirmed in the input, meaning this is not yet confirmed as actively exploited in the wild. The remediation priority should be elevated due to (1) root-level execution capability, (2) Cisco's explicit High SIR designation, and (3) the ability to escalate compromise across managed infrastructure, but the high authentication barrier limits immediate mass-exploitation risk. |
| Exploit ScenarioDerived | An authenticated administrator (insider threat or compromised admin account via phishing/credential theft) logs into the IMC web management interface and injects shell metacharacters into a management command field (e.g., a system settings parameter or configuration input). The injected payload executes additional arbitrary commands on the host operating system with root privileges, allowing the attacker to install persistence mechanisms, exfiltrate data, modify firmware, or pivot to other infrastructure systems managed by the same UCS environment. The attack requires prior knowledge of valid admin credentials but, once executed, fully compromises the management plane and underlying host. |

Alert meAnalysisAIv1 – Apr 01, 2026
Command injection in Cisco IMC web management interface allows authenticated admin-level attackers to execute arbitrary commands as root through improper input validation. Affects Cisco Enterprise NFV Infrastructure Software, Unified Computing System (standalone), and UCS E-Series platforms. No public exploit code or active exploitation confirmed at time of analysis, but the high-privileged context and root-level impact necessitate swift patching.
RemediationAI
Apply the patch released by Cisco for IMC. Consult the official Cisco Security Advisory at https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-cimc-cmd-inj-3hKN3bVt for specific fixed IMC firmware versions for each affected platform (Enterprise NFV Infrastructure, UCS standalone, and UCS E-Series). Until patches can be deployed, enforce strict network access controls to limit web-based management interface access to trusted administrative networks only, and audit IMC admin accounts for unauthorized activity or anomalous command patterns. Prioritize patching UCS and NFV infrastructure systems that manage critical business services or contain sensitive data.

Technical ContextAI · show details
Cisco Integrated Management Controller (IMC) is a baseboard management controller providing out-of-band management for Cisco UCS and related infrastructure platforms via a web-based interface. The vulnerability stems from CWE-77 (Improper Neutralization of Special Elements used in a Command), a command injection flaw where user-supplied input to the management interface is not properly validated before being passed to system command execution contexts. This allows authenticated administrators to inject shell metacharacters or command sequences that the underlying operating system interprets as additional commands, bypassing intended restrictions. The affected products include Cisco Enterprise NFV Infrastructure Software and Cisco UCS deployments (both standalone and E-Series variants), all of which rely on IMC for management operations.

DescriptionCVE.org
A vulnerability in the web-based management interface of Cisco IMC could allow an authenticated, remote attacker with admin-level privileges to perform command injection attacks on an affected system and execute arbitrary commands as the root user.
This vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by sending crafted commands to the web-based management interface of the affected software. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system as the root user. Cisco has assigned this vulnerability a Security Impact Rating (SIR) of High, rather than Medium as the score indicates, because additional security implications could occur once the attacker has become root.
