CVE-2024-49612 identifies a Blind SQL Injection vulnerability in the Sanjeev SW Contact Form plugin, affecting all versions up to 1.0. The vulnerability stems from improper neutralization of special characters in SQL commands, which allows attackers to craft malicious input that the backend database executes. Blind SQL Injection means the attacker cannot directly see the database output but can infer information based on application behavior or response times. This type of injection can be exploited to extract sensitive data, modify database contents, or escalate privileges within the application. The plugin is typically used in web environments to handle user-submitted contact forms, making it a common attack vector. No CVSS score has been assigned yet, and no patches or fixes have been officially released. The vulnerability was reserved and published in October 2024, indicating recent discovery. Exploitation requires sending specially crafted requests to the contact form endpoint, which does not require authentication, increasing the attack surface. The lack of known exploits in the wild suggests it is either newly discovered or under limited active exploitation. However, the potential for data leakage or unauthorized database manipulation is significant, especially for websites handling sensitive user information. The absence of official patches means organizations must rely on immediate mitigations such as input sanitization and web application firewalls to reduce risk.

The impact of CVE-2024-49612 can be severe for organizations using the vulnerable SW Contact Form plugin. Successful exploitation could lead to unauthorized disclosure of sensitive data stored in the backend database, including user information submitted via the contact form. Attackers might also manipulate or delete data, compromising data integrity and potentially disrupting business operations. Since the vulnerability allows blind SQL injection, attackers can systematically extract data even without direct feedback, increasing the risk of prolonged data breaches. The vulnerability affects the confidentiality and integrity of data and could indirectly impact availability if database corruption or denial-of-service conditions are triggered. Organizations relying on this plugin for customer communication or lead generation may face reputational damage, regulatory penalties, and financial losses if exploited. The ease of exploitation without authentication broadens the threat landscape, making public-facing websites particularly vulnerable. The lack of an official patch increases exposure time, emphasizing the need for proactive defenses.

To mitigate CVE-2024-49612, organizations should immediately implement strict input validation and sanitization on all data received through the SW Contact Form plugin, ensuring special characters are properly escaped or filtered before database queries. Deploying a web application firewall (WAF) with rules targeting SQL injection patterns can help block malicious requests. Monitoring web server and database logs for unusual query patterns or repeated failed attempts can aid in early detection of exploitation attempts. If possible, temporarily disabling or replacing the vulnerable contact form plugin with a secure alternative until an official patch is released is recommended. Developers maintaining the plugin should prioritize releasing a patch that uses parameterized queries or prepared statements to eliminate SQL injection risks. Additionally, organizations should review database permissions to ensure the contact form user account has the minimum required privileges, limiting potential damage from injection attacks. Regular backups of website and database content are essential to enable recovery in case of compromise. Finally, educating web administrators about the risks of SQL injection and the importance of timely updates will help reduce future vulnerabilities.
