CVE-2024-51626 identifies a Blind SQL Injection vulnerability in the chenyenming Woocommerce Quote Calculator plugin, specifically versions up to and including 1.1. The vulnerability arises from improper neutralization of special characters in SQL commands, allowing attackers to inject arbitrary SQL code into backend database queries. Blind SQL Injection means attackers cannot directly see database responses but can infer data by observing application behavior or timing differences. This flaw enables unauthorized attackers to extract sensitive information, modify database contents, or escalate privileges within the WordPress environment hosting the plugin. The plugin is used to provide quote calculation functionality in WooCommerce-based e-commerce sites. The vulnerability does not require authentication or user interaction, increasing its risk profile. Although no public exploits are currently reported, the nature of SQL injection vulnerabilities makes them attractive targets for attackers seeking to compromise e-commerce platforms. The lack of an official patch at the time of publication means affected users must rely on temporary mitigations. The vulnerability was published on November 4, 2024, and assigned by Patchstack, but no CVSS score has been provided. Given the plugin’s integration with WooCommerce, a widely used e-commerce platform, the potential attack surface is significant.

The impact of CVE-2024-51626 is substantial for organizations using the affected plugin. Successful exploitation can lead to unauthorized disclosure of sensitive customer and business data stored in the database, including order details, pricing, and potentially user credentials if stored insecurely. Attackers could also manipulate or delete data, disrupting business operations and damaging trust. The Blind SQL Injection nature complicates detection but does not reduce the severity, as attackers can still extract data over time. This vulnerability could be leveraged as a foothold for further attacks within the compromised environment, including privilege escalation or lateral movement. For e-commerce businesses, this could result in financial loss, regulatory penalties due to data breaches, and reputational damage. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate future exploitation potential. Organizations with high transaction volumes or sensitive customer data are particularly at risk.

1. Monitor for an official patch release from the plugin vendor and apply it immediately upon availability. 2. Until a patch is released, implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the plugin’s endpoints. 3. Conduct a thorough code review of the plugin’s source if feasible, focusing on input handling and SQL query construction, to apply temporary fixes such as parameterized queries or input sanitization. 4. Restrict database user permissions associated with the WordPress installation to the minimum necessary to limit damage from potential injection. 5. Enable detailed logging and monitoring to detect anomalous query patterns or unusual application behavior indicative of exploitation attempts. 6. Educate development and security teams about the vulnerability to ensure rapid response and remediation. 7. Consider isolating or disabling the plugin temporarily if it is not critical to business operations until a secure version is available. 8. Regularly back up databases and test restoration procedures to mitigate data loss risks.
