The Social Share, Social Login and Social Comments Plugin – Super Socializer plugin for WordPress is vulnerable to Limited SQL Injection via the ‘SuperSocializerKey’ parameter in all versions up to, and including, 7.14 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional values into the already existing query that can be used to extract user metadata from the database.
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.
