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 · unedited
An HTML injection/reflected Cross-site scripting (XSS) vulnerability was found in the ovirt-engine. A parameter "error_description" fails to sanitize the entry, allowing the vulnerability to trigger on the Windows Service Accounts home pages.

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 confidence

A reflected XSS vulnerability exists in ovirt-engine where the 'error_description' parameter is not properly sanitized before being rendered in HTML context on Windows Service Accounts home pages. An attacker could inject malicious HTML/JavaScript through this parameter, which executes when a user visits a crafted URL.

MitigationImplement proper output encoding/escaping for the error_description parameter before rendering, and validate/sanitize all user-supplied input in HTTP responses.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify ovirt-engine version
    Run 'rpm -q ovirt-engine' or check the engine database with 'SELECT product_version FROM engine_db'
    Affected if Version is exactly 4.3.0
  2. Confirm Windows Service Accounts feature is accessible
    Check if the Windows Service Accounts web UI endpoint is available by accessing the ovirt-engine admin portal and navigating to the Windows Service Accounts section
    Affected if The Windows Service Accounts home page is accessible to users
  3. Inspect error_description parameter handling
    Review the ovirt-engine web logs or HTTP traffic for the error_description parameter being reflected in responses without encoding
    Affected if The error_description value from the request is returned in the HTML response without proper sanitization

Your environment is affected if you are running ovirt-engine version 4.3.0 and have the Windows Service Accounts feature enabled, with the error_description parameter being reflected in HTML responses without encoding.
