Description
A vulnerability in the web-based management interface of Cisco IMC could allow an authenticated, remote attacker with low privileges to execute arbitrary commands on the underlying operating system of an affected system and elevate privileges to root. 

This vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by entering crafted inputs 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.

AI Analysis

Impact

The vulnerability stems from improper validation of user supplied arguments in the Cisco Integrated Management Controller web interface. An authenticated attacker with low privileges can craft input that is passed to the underlying operating system, allowing execution of arbitrary commands with root privileges. This creates a critical security gap where a compromised management session leads to full system control.

Affected Systems

Cisco Unified Computing System (Standalone) devices using the affected web‑based IMC software are impacted. The specific product and version information are not listed, so all firmware iterations that have not applied the latest Cisco patch should be treated as vulnerable.

Risk and Exploitability

With a CVSS score of 8.8, the bug is classified as high severity. The EPSS score is unavailable, but the lack of listing in the CISA KEV catalog suggests no known public exploitation yet. Attackers must first authenticate with a low‑privileged account, yet the flaw grants them a straight path to root, making the scenario highly dangerous for exposed management interfaces.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Apply the latest Cisco Unified Computing System (Standalone) firmware patch that resolves the argument injection flaw.
  • Restrict access to the IMC web interface to trusted administrators only, and disable or limit low‑privileged authentication for management tasks.
  • Configure network segmentation and firewall rules to block external access to the IMC management interface except from authorized management networks.
