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
A vulnerability was detected in Cockpit-HQ Cockpit up to 2.13.5. Affected by this issue is some unknown functionality of the component Asset Handler/Aggregate Handler. The manipulation results in improper neutralization of special elements in data query logic. It is possible to launch the attack remotely. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

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

This is a SQL injection vulnerability in Cockpit-HQ Cockpit CMS affecting the Asset Handler/Aggregate Handler component up to version 2.13.5. The vulnerability stems from improper neutralization of special elements in data query logic, allowing remote attackers to manipulate database queries. The exploit is publicly available, increasing risk.

MitigationSince the vendor did not respond to early disclosure, implement input validation and parameterized queries in the Asset Handler code; consider deploying a WAF rule to filter malicious SQL payloads as an interim control until an official patch is available.

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. Determine installed Cockpit CMS version
    Locate the version file or check the admin interface for the version number. Common locations include a composer.json, a version.php file, or the /api/server info endpoint.
    Affected if The installed version is 2.13.5 or lower, as versions up to 2.13.5 are affected by this SQL injection vulnerability.
  2. Identify if Asset Handler or Aggregate Handler is exposed
    Determine whether the Asset Handler or Aggregate Handler API endpoints are accessible. These are typically found under /api/asset/* or /api/aggregator/* routes depending on your configuration.
    Affected if The Asset Handler or Aggregate Handler component is exposed and reachable over the network without additional authentication barriers.
  3. Verify data query logic usage
    Review your codebase for usage of the Asset Handler or Aggregate Handler that processes user-supplied data in database queries. Look for direct query construction that accepts user input.
    Affected if The Asset Handler component processes user input in data query logic without proper sanitization or parameterized queries.
  4. Check for anomalous database behavior
    Monitor database logs and application logs for unusual or unexpected SQL query patterns, especially those containing SQL operators or commands that appear to be injected through asset/aggregate endpoints.

You are affected if your Cockpit CMS version is 2.13.5 or lower AND the Asset Handler/Aggregate Handler component is exposed and processes user input in database queries.
