Security readout for executives and security teams
Plain-English summary
This flaw can let a remote attacker delete files through Responsive FileManager 9.13.4. For a business, the main concern is service disruption, broken web applications, or loss of important server-side files if the file manager is reachable.
Executive priority
Prioritize investigation if the component is exposed on public websites or admin portals. Arbitrary deletion can cause outages and data loss, and public exploit information increases operational risk despite incomplete scoring data.
Technical view
CVE-2018-20790 is a path traversal mitigation bypass in the delete_file action of execute.php. The described issue involves the paths[0] parameter and can result in arbitrary file deletion. The provided sources do not include CVSS, CWE, patch details, or confirmed affected CPEs.
Likely exposure
Exposure is likely limited to environments running tecrail Responsive FileManager 9.13.4, especially if the component is internet-reachable or embedded in an admin interface. The bundle does not identify downstream packages or CPEs.
Exploitation context
The provided bundle does not show CISA KEV listing or confirmed active exploitation. Exploit-DB is cited, which indicates public exploit information exists. Treat reachable instances as urgent to investigate, but verify exploitation from logs and telemetry.
Researcher notes
Evidence is sparse: no CVSS vector, CWE mapping, patch reference, or CPEs are included. Analysis should stay anchored to Responsive FileManager 9.13.4 and the described delete_file path traversal bypass.
Mitigation direction
- Identify any Responsive FileManager 9.13.4 deployments.
- Check vendor or maintainer guidance for fixed versions.
- Disable or remove the component if it is unused.
- Restrict access to trusted administrators and networks.
- Back up and monitor sensitive application files.
Validation and detection
- Inventory web applications for Responsive FileManager references.
- Confirm the installed version, if present.
- Review web logs for suspicious delete_file requests.
- Check file integrity for unexpected deletions.
- Validate compensating access controls around file manager paths.
