Command Injection in Cisco IMC Web-Based Management Interface

IdentifiersCVE-2026-20094CWE-77· Improper Neutralization of Special…

CVE-2026-20094 is a command injection vulnerability in the web-based management interface of Cisco Integrated Management Controller (IMC). According to the provided content, the flaw is caused by improper validation of user-supplied input. An authenticated remote attacker with read-only privileges can send crafted commands to the IMC web interface and trigger command injection, resulting in arbitrary command execution on the underlying operating system. The injected commands execute with root privileges.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows a remote authenticated attacker with only read-only access to execute arbitrary commands on the affected system's underlying operating system as root. This can result in full compromise of the IMC-managed host, including complete loss of confidentiality, integrity, and availability, and enables privilege escalation from low-privileged IMC access to root-level OS command execution.

Mitigation

If you can’t patch tonight, do this now.

The provided content states that no workaround is available for this vulnerability. As compensating controls, restrict access to the Cisco IMC web management interface, do not expose IMC or other out-of-band management interfaces to the public internet, and place them in a separate management network with strong segmentation and access controls.

Remediation

Patch, then assume compromise.

Apply Cisco's fixed software updates for affected Cisco IMC and related NFVIS releases as quickly as possible. The provided content states that Cisco has published fixed-version guidance and upgrade paths in its security advisory for affected platforms, including Cisco UCS server lines and certain Cisco appliances built on vulnerable UCS platforms. Where applicable, upgrade affected NFVIS deployments to fixed releases identified by Cisco.
