CVE-2026-20094: Improper Neutralization of Special Elements used in a Command ('Command Injection') in Cisco Cisco Unified Computing System (Standalone)
A vulnerability in the web-based management interface of Cisco IMC could allow an authenticated, remote attacker with read-only 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.
AI Analysis
Technical Summary
This vulnerability arises from improper neutralization of special elements in user-supplied input within the Cisco IMC web interface, allowing command injection. An attacker with read-only authenticated access can send crafted commands to the interface, resulting in execution of arbitrary commands with root privileges on the underlying operating system. The affected product is Cisco Unified Computing System (Standalone), with many versions impacted. The CVSS 3.1 vector indicates network attack vector, low attack complexity, required privileges of low (authenticated read-only), no user interaction, unchanged scope, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows an authenticated attacker with read-only privileges to execute arbitrary commands as root, potentially leading to full system compromise including unauthorized data access, modification, or disruption of service. The high CVSS score (8.8) reflects the critical impact on confidentiality, integrity, and availability of the affected system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the web-based management interface to trusted administrators only and monitor for unusual activity. Do not rely on read-only privileges as a security boundary for this interface.
