Executive Summary

CVE-2025-9937 is a Broken Function Level Authorization vulnerability in elunez eladmin 1.1, specifically in the deleteFile method of the LocalStorageController. It allows a low-privileged user with the "storage:del" permission to delete files owned by other users because the system only checks for the permission but does not verify file ownership. The exploit involves sending a DELETE request with file IDs to delete files arbitrarily, leading to unauthorized file deletion. [1, 2]

Detection Guidance

This vulnerability can be detected by monitoring for unauthorized DELETE requests to the /api/localStorage endpoint, especially those containing JSON arrays of file IDs for deletion. Network traffic analysis tools or web application firewalls can be used to detect such suspicious requests. Specific commands are not provided in the resources, but inspecting HTTP DELETE requests targeting /api/localStorage with tools like curl or using network monitoring tools to log such requests may help identify exploitation attempts.

Mitigation Strategies

Immediate mitigation steps include restricting access to the /api/localStorage deleteFile function, monitoring and blocking unauthorized DELETE requests, and considering replacing the affected component with an alternative product as no known countermeasures or patches are documented. Applying strict access controls and limiting permissions to trusted users may reduce risk until a fix is available. [2]
