Simple Membership <= 4.0.3 - Authenticated (Admin+) SQL Injections
Strategic Overview
Vulnerability Overview
The Simple Membership plugin for WordPress is vulnerable to time-based SQL Injection via the 's' and 'status' parameters in versions up to, and including, 4.0.3 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 Admin+ attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
Technical Analysis
REMEDIATION: Update to version 4.0.4, or a newer patched version --- IDENTIFIER: CWE-89 (Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')) The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
