## Overview

Chanjet CRM contains an unauthenticated SQL injection vulnerability that allows remote attackers to execute arbitrary SQL queries by manipulating the site_id GET parameter in the webservice endpoint. Attackers can exploit the lack of input sanitization or parameterization through UNION-based injection techniques to extract sensitive data from the underlying database. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-18.
