Technical Analysis
Eladmin versions up to 2.7 contain a missing authorization vulnerability in the LocalStorageController uploadPicture handler. This flaw allows authenticated users with low privileges to bypass the intended storage:add permission check. Exploitation involves sending POST requests with image-named files to the /api/localStorage/pictures endpoint, which results in unauthorized file writes to the server's local storage and disclosure of absolute server paths.
Potential Impact
An attacker with low-level authentication can upload files to the server's local storage without proper authorization and gain knowledge of absolute server paths. This could lead to unauthorized data manipulation or information disclosure. The CVSS 4.0 base score is 5.3, indicating a medium severity impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the /api/localStorage/pictures endpoint to trusted users only and monitor for suspicious POST requests targeting this endpoint.
