Description

The ARMember Premium plugin for WordPress is vulnerable to SQL Injection via the 'sSortDir_0' parameter of the `get_private_content_data` AJAX action in all versions up to, and including, 7.3.1. This is due to insufficient sanitization of the user-supplied parameter which is concatenated directly into the ORDER BY clause of an SQL query without a whitelist check. This makes it possible for authenticated attackers, with Subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Note: The vulnerability can only be exploited if the "User Private Content" addon is enabled, which is disabled by default..

• CWE-89Improper 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.
