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
Vulnerability in Fidelis Network and Deception CommandPost enables authenticated command injection through the web interface using the “update_checkfile” value for the “filename” parameter. The vulnerability could allow a specially crafted HTTP request to execute system commands on the CommandPost and return results in an HTTP response via an authenticated session. The vulnerability is present in Fidelis Network and Deception versions prior to 9.4.5. Patches and updates are available to address this vulnerability.

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 confidence

Authenticated command injection vulnerability in Fidelis Network and Deception CommandPost web interface. Attackers can execute arbitrary system commands by submitting specially crafted HTTP requests with malicious 'filename' parameter values to the 'update_checkfile' endpoint. Results are returned in the HTTP response.

MitigationUpdate Fidelis Network and Deception to version 9.4.5 or later to apply vendor patches. Alternatively, restrict web interface access to only trusted administrative users and monitor for suspicious requests.

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 Fidelis product and version
    Locate the Fidelis installation and retrieve the installed version number. This is typically visible in the CommandPost login page footer, admin console, or via system information commands provided by the product documentation.
    Affected if The installed version is Fidelissecurity Deception or Fidelissecurity Network and the version is below 9.4.5
  2. Confirm CommandPost web interface is accessible
    Verify that the CommandPost web interface is enabled and network-accessible. This is typically accessed over HTTPS on port 443 or a custom port. Attempt to reach the login page.
    Affected if The web interface is exposed and accessible (this is required for the vulnerability to be exploitable)
  3. Inspect HTTP access logs for update_checkfile requests
    Examine the CommandPost web server access logs (typically found in /var/log/ or product-specific log directories) for POST requests to the 'update_checkfile' endpoint. Look for requests containing unusual patterns in the 'filename' parameter such as semicolons, pipe symbols, backticks, or command separators.
    Affected if Logs show POST requests to update_checkfile with suspicious filename parameter values containing command injection patterns
  4. Check for unauthorized command execution indicators
    Review system logs, audit logs, or CommandPost logs for evidence of unexpected command execution, spawned processes, or privilege escalation that correlates with the timing of any suspicious update_checkfile requests.
    Affected if Logs or system artifacts show unexpected command execution that cannot be attributed to legitimate administrative actions

A user is affected if they run Fidelissecurity Deception or Network with a version lower than 9.4.5 and have the CommandPost web interface exposed, with evidence of suspicious update_checkfile requests or unauthorized command execution in logs.
