Executive brief
The Barangay Resident Profiling Management System (BRPMS) is a web application for managing resident profiles and records in local government. An authenticated user can manipulate a resident ID parameter to restore or permanently delete archived resident records belonging to other users without proper authorization checks, compromising data integrity and allowing unauthorized deletion of resident information.
Technical details
The vulnerability is an Insecure Direct Object Reference (IDOR) and authorization bypass in the /archived_records.php endpoint. The vulnerable code accepts a user-controlled resident_id parameter in POST requests and performs UPDATE or DELETE operations on the residents table without validating that the authenticated user is authorized to act on that specific record. For restore operations, no authorization check is performed beyond authentication. For permanent deletion, the application only verifies the user's own password, which proves identity but not authorization to delete the target record. An authenticated attacker can restore arbitrary archived records or delete any resident record if they know their own password. No patch information is currently available; the vulnerability is marked unpatched.
