WordPress Front End Users Plugin SQL Injection Vulnerability

A SQL injection vulnerability has been identified in the Front End Users plugin for WordPress, affecting all versions through 3.2.32. The issue arises from inadequate escaping of user-supplied data in the 'UserSearchField' parameter, coupled with a lack of proper preparation for the SQL query. This vulnerability allows unauthenticated attackers to inject additional SQL commands into existing queries, potentially leading to the extraction of sensitive information from the database.

Impact

Exploitation of this vulnerability allows for SQL injection, where attackers can manipulate SQL queries to access or modify database information. In this case, it could be used to extract sensitive data from the database.

Reproduction

To reproduce this vulnerability, send a request to the WordPress site with the 'UserSearchField' parameter. The absence of proper input sanitization will allow the injection of malicious SQL code, which can then be executed by the database. This can be done by an unauthenticated user, taking advantage of the plugin's vulnerability.

Remediation

No known patch is available. It is recommended to uninstall the affected plugin and consider a replacement.
