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
There is a Path Traversal that leads to a Local File Inclusion in Pandora FMS v764. A function is called to check that the parameter that the user has inserted does not contain malicious characteres, but this check is insufficient. An attacker could insert an absolute path to overcome the heck, thus being able to incluse any PHP file that resides on the disk. The exploitation of this vulnerability could lead to a remote code execution.

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

A path traversal vulnerability in Pandora FMS v764 allows attackers to bypass an input validation function using absolute paths, enabling inclusion of arbitrary PHP files from the filesystem. The existing security check is insufficient as it fails to block absolute path inputs, which can lead to remote code execution.

MitigationFix the path validation function to properly reject absolute paths and implement additional sanitization; consider upgrading to a patched version if 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. Confirm Pandora FMS installation
    Locate the Pandora FMS installation directory, typically found at /var/www/html/pandora or check the web server document root for pandora_fts.php or other Pandora FMS PHP files
    Affected if Pandora FMS is not installed on the system
  2. Identify installed version
    Check the version file or dashboard within Pandora FMS. Common locations include a version.php file in the include directory or the system info page in the web UI
    Affected if The installed version is less than 766 (v764 is specifically mentioned as vulnerable)
  3. Locate vulnerable include file
    Search for the file containing the include_or_extend_function or similar path validation function in the Pandora FMS include directory, typically named include/*.php
    Affected if The file exists and contains path validation logic that accepts absolute paths as input
  4. Verify path validation behavior
    Examine the validation function code - specifically check if the security check only validates relative paths and fails to reject absolute path inputs like /etc/passwd
    Affected if The validation function does not reject or sanitize absolute path inputs, allowing traversal
  5. Check web server access
    Confirm the Pandora FMS web interface is accessible and the include functionality can be reached via HTTP requests to the affected endpoint
    Affected if The vulnerable endpoint is reachable without additional authentication or the authentication can be bypassed

A system is affected if it runs Pandora FMS version 764 or any version below 766 where the path validation function permits absolute path inputs to include arbitrary PHP files.
