Detailsinfo

A vulnerability, which was classified as critical, was found in ARMember Premium Plugin up to 7.3.1 on WordPress. Affected is the function arm_get_directory_members of the component AJAX Action Handler. The manipulation of the argument order/orderby with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as CWE-89. 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. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The ARMember Premium plugin for WordPress is vulnerable to SQL Injection via the 'order' parameter of the 'arm_directory_paging_action' AJAX action in all versions up to, and including, 7.3.1. This is due to insufficient escaping on the user-supplied 'order' and 'orderby' parameters and the lack of sufficient preparation on the existing SQL query in the `arm_get_directory_members()` function. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
