CVE-2021-27658
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 · uneditedexacqVision Enterprise Manager 20.12 does not sufficiently validate, filter, escape, and/or encode user-controllable input before it is placed in output that is used as a web page that is served to other users.
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 · moderate confidenceexacqVision Enterprise Manager 20.12 contains a cross-site scripting (XSS) vulnerability where user-supplied input is not properly validated, filtered, escaped, or encoded before being rendered in web pages served to other users. This allows authenticated attackers to inject malicious JavaScript or HTML into web interfaces.

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 if exacqVision Enterprise Manager is installedLook for the exacqVision Enterprise Manager service or application in your system. Check for installation directories typically under C:\Program Files\exacqVision\Enterprise Manager or /opt/exacqvision/ on Linux systems.Affected if The application is present on the system
-
Determine the installed version of exacqVision Enterprise ManagerOpen the Enterprise Manager application and navigate to Help > About, or check the version in the installed software list (Windows Add/Remove Programs, Linux package manager). Compare the version number to 20.12.Affected if The installed version is 20.12 or any earlier version (<= 20.12)
-
Verify the web interface is accessibleAccess the Enterprise Manager web interface by navigating to https://localhost:8081 or the configured server address in a web browser. Confirm the login page loads.Affected if The web interface is reachable and accepts authentication
-
Confirm authentication is enabled for the web interfaceCheck the Enterprise Manager server configuration to ensure user authentication is not disabled. Attempt to log in with valid credentials or check authentication settings in the admin panel.Affected if Authentication is enabled and user accounts exist in the system
If exacqVision Enterprise Manager is installed with version 20.12 or earlier and the web interface is accessible with authentication enabled, the environment is affected by this XSS vulnerability.

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 dataImplement context-aware output encoding and input validation for all user-controllable fields in the web application. Consider deploying Content Security Policy (CSP) headers as an additional defense-in-depth measure.
