The SQL Injection vulnerability in the Country State City Dropdown CF7 plugin allows attackers to manipulate SQL queries by exploiting insufficient input escaping and preparation. This can lead to unauthorized access and extraction of sensitive data from the database. The vulnerability affects the 'cnt' and 'sid' parameters in versions up to and including 2.7.2. Exploitation of this vulnerability requires no authentication, making it a critical security risk.
The Country State City Dropdown CF7 plugin has a SQL Injection vulnerability due to inadequate escaping and preparation of user-supplied input. Specifically, the 'cnt' and 'sid' parameters in AJAX requests are vulnerable. Attackers can inject malicious SQL queries via these parameters, leading to the execution of arbitrary SQL commands. The issue is present in the 'tc_csca_get_cities' function in the 'admin-ajax.php' file. This vulnerability can be exploited remotely without authentication, potentially compromising the entire database.
Exploitation of the SQL Injection vulnerability can lead to severe consequences, including unauthorized access to sensitive data, such as user credentials and personal information. Attackers may execute arbitrary SQL commands, leading to data manipulation or deletion. This could result in website defacement, data loss, or unauthorized administrative access. The overall security and integrity of the affected WordPress site could be significantly compromised.
