CVE-2025-20356
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability in the web-based management interface of Cisco Cyber Vision Center could allow an authenticated, remote attacker to conduct cross-site scripting (XSS) attacks against a user of the interface. This vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected system. An attacker could exploit this vulnerability by injecting malicious code into specific pages of the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. To exploit this vulnerability, the attacker must have valid administrative credentials that allow access to the Sensor Explorer page. By default, Admin and Product user roles have this access, as do any custom users that are configued to allow access to the Sensors page.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThis is a stored Cross-Site Scripting (XSS) vulnerability in Cisco Cyber Vision Center's web-based management interface. The flaw stems from insufficient validation of user-supplied input on the Sensor Explorer page (and potentially related pages), allowing an authenticated attacker with administrative credentials to inject malicious script code that executes in the context of other users' browsers.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Cisco Cyber Vision Center versionAccess the web management interface and navigate to the About or System Information section, typically found under Administration or Help menus. Alternatively, use the CLI if available and check the software version displayed on login or via a version command.Affected if The installed version is 5.2.0 or any version lower than 5.2.0 (e.g., 5.1.x, 5.0.x, earlier releases).
-
Confirm web-based management interface is activeVerify that the Cisco Cyber Vision Center web interface is running and accessible by attempting to reach the login page via HTTPS or HTTP on the configured management port (default ports are 443 or 8443).Affected if The web management interface is exposed and reachable on the network.
-
Check for administrative user accountsReview user accounts configured in Cisco Cyber Vision Center. Access the User Management or Users section within the Administration menu of the web interface to enumerate accounts with administrative privileges.Affected if There exists at least one account with administrative-level access to the web interface.
-
Verify Sensor Explorer page accessibilityLog into the web interface with administrative credentials and navigate to the Sensor Explorer page (typically found under the Exploration or Sensors menu). Confirm the page loads and accepts user input.Affected if The Sensor Explorer page is accessible and functional for administrative users, allowing input that could potentially store malicious scripts.
You are affected if Cisco Cyber Vision Center version 5.2.0 or lower is installed, the web management interface is accessible, and administrative users exist who can access the Sensor Explorer page.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the vendor patch when released; in the interim, restrict administrative access to the Sensor Explorer page to only essential personnel and implement Content Security Policy (CSP) headers as defense-in-depth.
