At a glance
This record tracks a critical-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the Premium Courses & eLearning with Paid Memberships Pro for LearnDash, LifterLMS, Sensei LMS & TutorLMS WordPress plugin, affecting versions <= 1.0.5. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 1.1; sites on affected versions should update now. Disclosed June 2022.
Vulnerability Overview
The Premium Courses & eLearning plugin for WordPress is vulnerable to SQL Injection via the ‘level_ids’ parameter in several of its modules in versions up to, and including, 1.0.5 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Premium Courses & eLearning with Paid Memberships Pro for LearnDash, LifterLMS, Sensei LMS & TutorLMS <= 1.0.5 carries this weakness at level_ids, and reaching it takes a caller who can reach the endpoint. SQL injection happens when request data is concatenated into a query instead of being bound as a parameter, letting an attacker change the structure of the statement rather than just its values.
A working injection can read any table the database user can see, which on a WordPress install means user records, password hashes and session or API secrets stored in options. For Premium Courses & eLearning with Paid Memberships Pro for LearnDash, LifterLMS, Sensei LMS & TutorLMS the fix is 1.1: builds <= 1.0.5 are affected, anything from 1.1 onward is not.
Remediation
Update to version 1.1, or a newer patched version
How does WordSec protect against this?
