Security readout for executives and security teams
This old PHP-Nuke flaw concerns opendir.php. The script could let a remote visitor ask the server to return files by passing a filename through requesturl. The business risk is exposure of local files, potentially including configuration or credentials, but the provided sources do not identify affected versions, a vendor patch, or confirmed active exploitation. Exposure is most likely limited to legacy PHP-Nuke deployments that include and expose opendir.php. The source bundle does not define affected versions or CPEs, so inventory validation is required before assuming exposure. Treat this as a legacy exposure discovery task. It is not KEV-listed and lacks current severity data, but any exposed instance could leak sensitive files. Prioritize confirmation and containment over broad emergency response. Mitigation focus: Identify any PHP-Nuke installations and whether opendir.php is present.; Restrict or remove public access to opendir.php if it is not required.; Check vendor or maintainer guidance for fixed PHP-Nuke releases or official workarounds..
