What the vulnerability does
01Description
The ARMember – Membership Plugin, Content Restriction, Member Levels, User Profile & User signup plugin for WordPress is vulnerable to time-based blind SQL Injection via the 'orderby' parameter in all versions up to, and including, 4.0.60 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query.
