CVE-2026-20088: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in Cisco Cisco Enterprise NFV Infrastructure Software
A vulnerability in the web-based management interface of Cisco IMC could allow an authenticated, remote attacker with administrative privileges to conduct a stored XSS attack against a user of the interface. This vulnerability is due to insufficient validation of user input. An attacker could exploit this vulnerability by persuading a user of an affected interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the browser of the targeted user or access sensitive, browser-based information.
AI Analysis
Technical Summary
This vulnerability in Cisco Enterprise NFV Infrastructure Software's web management interface allows an authenticated administrator to perform stored XSS attacks due to improper input neutralization. The attacker can inject malicious scripts that execute in the context of other users' browsers, potentially exposing sensitive browser-based information. Exploitation requires user interaction (clicking a crafted link) and administrative privileges. The vulnerability affects numerous versions of the software and is rated medium severity with a CVSS 3.1 score of 4.8.
Potential Impact
Successful exploitation could allow an attacker to execute arbitrary script code in the browser of a targeted user of the management interface, potentially leading to disclosure of sensitive information accessible via the browser. The impact is limited to confidentiality and integrity of browser-based data, with no direct impact on availability. Exploitation requires administrative privileges and user interaction.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict administrative access to trusted users only and educate users to avoid clicking untrusted links within the management interface. Monitor Cisco's advisories for updates on patches or official mitigations.
