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
Northern.tech CFEngine Enterprise before 3.10.7, 3.11.x and 3.12.x before 3.12.3, 3.13.x, and 3.14.x allows XSS. This is fixed in 3.10.7, 3.12.3, and 3.15.0.

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

Cross-site scripting (XSS) vulnerability in Northern.tech CFEngine Enterprise web interface allows remote attackers to inject malicious scripts via unspecified vectors. The vulnerability affects multiple version branches (3.10.x before 3.10.7, 3.11.x, 3.12.x before 3.12.3, 3.13.x, and 3.14.x).

MitigationUpgrade CFEngine Enterprise to version 3.10.7, 3.12.3, or 3.15.0 (or later) to remediate the XSS vulnerability.

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 installed CFEngine Enterprise version
    Run `cf-agent --version` or `cf-promises --version` on the hub server to retrieve the exact version number
    Affected if The version returned is 3.10.0 through 3.10.6, 3.11.x, 3.12.0 through 3.12.2, 3.13.x, 3.14.x, or 3.7
  2. Confirm Mission Portal web interface is active
    Check if the CFEngine Mission Portal service is running. On systemd systems run `systemctl status cfengine-commander` or inspect the configuration file (typically in /var/cfengine/httpd/ or check for port 80/443 listeners)
    Affected if The Mission Portal web interface is exposed and the CFEngine version falls within the affected ranges listed above
  3. Compare version against security advisory ranges
    Review the version number obtained in step 1 against the affected branches: 3.10.x before 3.10.7, 3.11.x, 3.12.x before 3.12.3, 3.13.x, and 3.14.x (also version 3.7)
    Affected if Your installed version matches any of these affected branches

You are affected if CFEngine Enterprise with an exposed Mission Portal web interface is running a version within the 3.10.0-3.10.6, 3.11.x, 3.12.0-3.12.2, 3.13.x, 3.14.x, or 3.7 branches.
