CVE-2025-5306
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 · uneditedImproper Neutralization of Special Elements in the Netflow directory field may allow OS command injection. This issue affects Pandora FMS 774 through 778
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 confidenceImproper input validation in the Netflow directory field of Pandora FMS versions 774-778 allows attackers to inject malicious OS commands through the field. The vulnerability stems from the application passing unsanitized user input from the Netflow directory parameter directly to system shell operations, enabling arbitrary command execution with the privileges of the web server.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify Pandora FMS installation and versionCheck the Pandora FMS version file or login to the web interface and navigate to Admin > Setup > System info. Common version files include /usr/share/pandora_fms/pandora_console/include/config.php or /var/www/html/pandora_console/pandora_version.txtAffected if The installed version is greater than or equal to 774 and less than or equal to 778
-
Confirm Netflow module is enabledIn the Pandora FMS web interface, go to Netflow > Netflow settings or examine the configuration file (usually pandora_netflow.conf in /etc/pandora or the database) to verify the Netflow feature is activeAffected if Netflow is enabled and configured on the system
-
Inspect Netflow directory configurationAccess Netflow settings in the web interface (Netflow > Netflow > Live view or Netflow > Netflow > Data management) and check the Directory field value. Alternatively, query the database table tnetflow_definition or look for netflow_dir in the configuration filesAffected if The Netflow directory field contains special shell characters such as ;, |, &, $, `, or backticks that were not properly sanitized
-
Review web server process privilegesCheck the user running the web server process (typically apache, www-data, or nginx) using 'ps aux | grep -E "apache|nginx|httpd"' to understand the privilege level at which command injection would executeAffected if The web server runs with elevated privileges, increasing the impact of command injection
You are affected if Pandora FMS version 774-778 is installed AND the Netflow module is enabled with a directory field containing unsanitized shell metacharacters.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor patch immediately. If no patch available, restrict access to Netflow configuration interfaces and implement input validation/regex filtering on the directory field to reject special shell characters (;, |, &, $, `, etc.) until a fix is deployed.
