CVE-2024-0709 is a critical SQL Injection vulnerability identified in the Cryptocurrency Widgets – Price Ticker & Coins List WordPress plugin developed by narinder-singh, affecting versions 2.0 through 2.6.5. The vulnerability stems from insufficient escaping and lack of prepared statements when handling the 'coinslist' parameter in SQL queries. This improper neutralization of special elements in SQL commands (CWE-89) allows unauthenticated attackers to append arbitrary SQL code to existing queries. As a result, attackers can execute unauthorized SQL commands against the backend database, potentially extracting sensitive data such as user credentials, financial information, or configuration details, modifying data, or causing denial of service by corrupting or deleting data. The vulnerability requires no authentication or user interaction, increasing its exploitability. The CVSS 3.1 base score of 9.8 reflects the vulnerability's critical nature, with network attack vector, low attack complexity, no privileges required, and no user interaction needed. While no public exploits are currently known, the widespread use of WordPress and the popularity of cryptocurrency-related plugins increase the risk of exploitation. The lack of official patches at the time of disclosure necessitates immediate mitigation efforts by administrators.

The impact of CVE-2024-0709 is severe for organizations using the affected plugin. Successful exploitation can lead to full compromise of the underlying WordPress site's database, exposing sensitive data including user information, API keys, and possibly financial transaction data related to cryptocurrency widgets. This can result in data breaches, loss of customer trust, regulatory penalties, and financial losses. Additionally, attackers could modify or delete critical data, leading to service disruption or defacement of websites. Since the vulnerability is exploitable without authentication or user interaction, automated attacks and mass exploitation campaigns are plausible, increasing the risk for organizations worldwide. Cryptocurrency-related websites and services are particularly attractive targets due to the high value of the data involved. The vulnerability also poses reputational risks and could be leveraged as a foothold for further network intrusion.

1. Immediate action should be to update the Cryptocurrency Widgets – Price Ticker & Coins List plugin to a patched version once available from the vendor. 2. Until an official patch is released, disable or remove the vulnerable plugin to eliminate exposure. 3. Implement Web Application Firewall (WAF) rules specifically targeting SQL Injection attempts on the 'coinslist' parameter to block malicious payloads. 4. Conduct thorough input validation and sanitization on all user-supplied inputs, especially parameters used in SQL queries. 5. Employ parameterized queries or prepared statements in plugin code to prevent injection vulnerabilities. 6. Monitor web server and database logs for unusual query patterns or errors indicative of attempted exploitation. 7. Regularly back up databases and website content to enable recovery in case of data corruption or deletion. 8. Educate site administrators about the risks of installing unverified plugins and maintaining timely updates. 9. Consider deploying intrusion detection systems (IDS) to detect exploitation attempts. 10. Review and restrict database user permissions to limit the impact of potential SQL Injection attacks.
