Executive Summary

CVE-2026-5482 is a vulnerability in the Responsive FileManager software developed by Tecrail. It allows an unauthenticated attacker to upload files of any type and extension without restriction using the dialog.php endpoint.

This unrestricted file upload can lead to Remote Code Execution, meaning the attacker can execute arbitrary code on the affected system.

The vulnerability affects all versions up to and including 9.14.0, and the project is currently unmaintained.

Detection Guidance

The vulnerability involves an unauthenticated attacker uploading files of any type or extension through the dialog.php endpoint in Responsive FileManager. Detection would involve monitoring for unexpected or unauthorized file uploads to this endpoint.

Since the project is unmaintained and no specific detection commands or tools are provided in the available resources, general detection methods include checking web server logs for POST requests to dialog.php that include file uploads, especially those with suspicious file types or extensions.

• Use web server access logs to identify POST requests to dialog.php, e.g., using grep: grep 'POST /path/to/dialog.php' /var/log/apache2/access.log
• Look for unusual file uploads or files with suspicious extensions in the upload directories.
• Use intrusion detection systems (IDS) or web application firewalls (WAF) to alert on file uploads to dialog.php.

Mitigation Strategies

Since the Responsive FileManager project is unmaintained and the vulnerability allows unauthenticated file uploads leading to remote code execution, immediate mitigation steps are critical.

• Disable or restrict access to the dialog.php endpoint to prevent unauthorized file uploads.
• Implement network-level controls such as firewall rules to block access to the vulnerable endpoint.
• If possible, remove or replace Responsive FileManager with a maintained alternative that does not have this vulnerability.
• Monitor your system for any signs of exploitation or unauthorized file uploads.
