Description

HaPe PKH 1.1 fails to enforce authorization on its record deletion endpoints, allowing unauthenticated attackers to delete arbitrary records by sending a crafted request that specifies the target record's id. The admin/modul/mod_pengurus/aksi_pengurus.php (module=pengurus&act=hapus) and admin/modul/mod_update/aksi_update.php (module=update&act=hapus) endpoints process deletions without verifying the requester's privileges, enabling removal of pengurus (administrator) and update records.
