Catalyst Connect Zoho CRM Client Portal <= 2.2.0 - Authenticated (Administrator+) SQL Injection via uid Parameter
Description
The Catalyst Connect Zoho CRM Client Portal plugin for WordPress is vulnerable to time-based SQL Injection via the ‘uid’ parameter in all versions up to, and including, 2.2.0 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 attackers, with Administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Summary
The Catalyst Connect Zoho CRM Client Portal plugin for WordPress is vulnerable to time-based SQL Injection via the 'uid' parameter in versions up to 2.2.0. This occurs due to insufficient escaping of user input and a lack of SQL statement preparation, allowing authenticated administrators to extract sensitive database information.
Exploit Outline
To exploit this vulnerability, an attacker must first authenticate with Administrator-level privileges. The attacker then targets an administrative endpoint or functionality that processes the 'uid' parameter. By supplying a payload containing SQL syntax designed to trigger a time delay (e.g., using the SLEEP() function) through the 'uid' parameter, the attacker can confirm the injection and use boolean-based or time-based techniques to exfiltrate data from the WordPress database.
