CVE-2026-20097: Out-of-bounds Write 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 admin-level privileges to execute arbitrary code as the root user. This vulnerability is due to improper validation of user-supplied input to the web-based management interface. An attacker could exploit this vulnerability by sending crafted HTTP requests to an affected device. A successful exploit could allow the attacker to execute arbitrary code on the underlying operating system as the root user. Cisco has assigned this vulnerability a SIR of High rather than Medium as the score indicates because additional security implications could occur when the attacker becomes root.
AI Analysis
Technical Summary
This vulnerability involves an out-of-bounds write in the web-based management interface of Cisco Unified Computing System (Standalone). An authenticated attacker with administrative privileges can send specially crafted HTTP requests that exploit improper input validation, leading to arbitrary code execution with root privileges on the underlying operating system. The vulnerability affects numerous versions of Cisco UCS software. Cisco assigned a CVSS v3.1 score of 6.5 (medium severity) but internally rates the security impact as High due to the elevated privileges gained by an attacker. No patch or remediation details are included in the provided data.
Potential Impact
Successful exploitation allows an authenticated attacker with admin-level access to execute arbitrary code as the root user on the affected system. This could lead to full system compromise, unauthorized control, and potential disruption of services managed by Cisco UCS. The vulnerability does not affect availability directly but impacts confidentiality and integrity significantly.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since the vulnerability requires authenticated admin-level access, ensure that administrative credentials are tightly controlled and monitored. Follow Cisco's official advisories for updates on patches or workarounds. Avoid exposing the management interface to untrusted networks and restrict access to trusted administrators only.
