Vulnerability Title
The School Management <= 5.4 - Authenticated (Custom+) SQL Injection via 'order[0][dir]' Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The The School Management – Education & Learning ERP plugin for WordPress is vulnerable to generic SQL Injection via 'order[0][dir]' Parameter in all versions up to, and including, 5.4 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with custom-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This vulnerability is replicated across seven or more AJAX handlers including wlsm-fetch-staff-classes, wlsm-fetch-notices, wlsm-fetch-subjects, wlsm-fetch-inquiries, wlsm-fetch-staff-employee, and wlsm-fetch-payments, and the missing nonce verification on several of these handlers also enables CSRF-chained exploitation.
