Summary
OpenEMR before 8.2.0 contains a path traversal vulnerability in the standard_tables_manage.php interface where the db GET parameter is passed without validation to temp_dir_cleanup(), which joins the value to the PHP temporary directory path and recursively deletes the resulting directory. Attackers can supply a traversal sequence in the db parameter to resolve outside the intended temporary directory, and by chaining this with an open redirect in dicom_frame.php, an unauthenticated attacker can deliver a crafted URL that triggers arbitrary recursive directory deletion within an authenticated Superuser's session.
Risk Assessment
An unauthenticated attacker can cause recursive directory deletion on the system, potentially leading to data loss and disruption of application functionality.
Recommendation
Update OpenEMR to version 8.2.0 or later to mitigate the path traversal vulnerability.
