CVE-2026-20089: 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 attacker with admin rights to perform stored XSS attacks due to improper input validation. The attacker can inject malicious scripts that execute in other users' browsers when they interact with crafted links. The flaw impacts many versions of the software, with a CVSS 3.1 score of 4.8 (medium severity). No patch or official remediation information is currently available, and no public exploits have been observed.
Potential Impact
Successful exploitation could enable execution of arbitrary script code in the context of the targeted user's browser session or unauthorized access to sensitive browser-based information. This could lead to session hijacking or information disclosure within the management interface. The attack requires administrative privileges and user interaction (clicking a crafted link). There is no indication of impact on system availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, limit administrative access to trusted users and avoid clicking suspicious links within the management interface. Monitor Cisco's official channels for updates and patches addressing this vulnerability.
