CVE-2024-12270 identifies a SQL Injection vulnerability in the Beautiful taxonomy filters plugin for WordPress, specifically in the handling of the 'selects[0][term]' parameter. The plugin versions up to and including 2.4.3 fail to properly escape or prepare SQL queries involving this parameter, allowing attackers to append arbitrary SQL commands. This vulnerability is classified under CWE-89, indicating improper neutralization of special elements in SQL commands. The flaw enables unauthenticated remote attackers to execute unauthorized SQL queries, potentially extracting sensitive information from the backend database. The vulnerability has a CVSS 3.1 base score of 7.5, reflecting high severity due to network attack vector, low attack complexity, no privileges required, and no user interaction needed. While no public exploits have been reported yet, the vulnerability's characteristics make it a prime target for exploitation. The lack of patch links suggests that a fix may not yet be publicly available, emphasizing the need for defensive measures. The vulnerability impacts confidentiality but does not affect integrity or availability directly. The plugin is widely used in WordPress environments, increasing the scope of affected systems globally.

The primary impact of CVE-2024-12270 is unauthorized disclosure of sensitive information stored in the WordPress site's database. Attackers can exploit the SQL Injection flaw to extract data such as user credentials, personal information, or other confidential content, potentially leading to privacy breaches and compliance violations. Since the vulnerability requires no authentication or user interaction, any publicly accessible WordPress site using the vulnerable plugin is at risk. This can lead to reputational damage, legal consequences, and financial losses for affected organizations. Although the vulnerability does not directly compromise data integrity or availability, the exposure of sensitive data can facilitate further attacks, including privilege escalation or targeted phishing campaigns. The widespread use of WordPress and the plugin increases the potential attack surface, making this a significant threat to organizations worldwide, especially those handling sensitive or regulated data.

1. Monitor the vendor's official channels for a security patch or update addressing CVE-2024-12270 and apply it immediately upon release. 2. Until a patch is available, implement web application firewall (WAF) rules to detect and block malicious SQL injection attempts targeting the 'selects[0][term]' parameter. 3. Employ input validation and sanitization on all user-supplied data, particularly parameters used in SQL queries, to prevent injection. 4. Where possible, modify the plugin code to use parameterized queries or prepared statements to eliminate direct concatenation of user input into SQL commands. 5. Conduct regular security audits and vulnerability scans focusing on WordPress plugins to identify and remediate similar issues proactively. 6. Limit database user permissions to the minimum necessary to reduce the impact of potential SQL injection exploitation. 7. Maintain regular backups of website data to enable recovery in case of compromise. 8. Educate site administrators about the risks of using outdated or unpatched plugins and encourage timely updates.
