CVE-2026-20085 - Vulnerability Details

- Cisco Integrated Management Controller Cross-Site Scripting Vulnerability

Description

A vulnerability in the web-based management interface of Cisco IMC could allow an unauthenticated, remote attacker to conduct a reflected 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.

Analysis

Impact

The CVE describes a reflected cross‑site scripting flaw in the Cisco Integrated Management Controller web interface. An unauthenticated attacker can convince a user to click a crafted URL, causing the browser to execute arbitrary JavaScript. The result can be theft of session cookies, privilege escalation within the web application, or other malicious actions performed with the user’s credentials. This vulnerability arises from insufficient input validation, classifying it as a standard reflected XSS weakness (CWE‑79).

Affected Systems

The flaw affects Cisco’s Enterprise NFV Infrastructure Software, the standalone Cisco Unified Computing System, and the Cisco Unified Computing System E‑Series Software. No specific version numbers are supplied in the advisory, so all current releases should be examined for the presence of the issue.

Risk and Exploitability

With a CVSS score of 6.1 the risk is moderate. The exploit requires only a malicious link delivered to a user of the web console; the attacker does not need authentication. EPSS data is not available and the vulnerability is not listed in the CISA KEV catalogue, indicating no public exploitation reports yet. Nonetheless, any user who approves the crafted link could lose control of the console session or expose sensitive information.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

Description		A vulnerability in the web-based management interface of Cisco IMC could allow an unauthenticated, remote attacker to conduct a reflected 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.
