CVE-2026-20200: Improper Neutralization of Parameter/Argument Delimiters 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 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
Technical Summary
This vulnerability affects the Cisco Unified Computing System (Standalone) web-based management interface. Due to improper neutralization of parameter or argument delimiters, an authenticated attacker with low privileges can input crafted data that leads to arbitrary command execution on the underlying OS with root privileges. The vulnerability is caused by insufficient input validation in the management interface, allowing privilege escalation and full system compromise.
Potential Impact
Successful exploitation results in arbitrary command execution on the underlying operating system with root privileges. This can lead to complete system compromise, including confidentiality, integrity, and availability impacts. The CVSS 3.1 base score is 8.8, reflecting network attack vector, low attack complexity, low privileges required, no user interaction, and high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary mitigation has been documented in the provided data. Until a patch is available, restrict access to the management interface to trusted users and networks, and monitor for suspicious activity related to command execution attempts.
