CVE-2024-6353 is an SQL Injection vulnerability identified in the Wallet for WooCommerce plugin for WordPress, affecting all versions up to and including 1.5.4. The vulnerability stems from improper neutralization of special elements in SQL commands (CWE-89) specifically via the 'search[value]' parameter. This parameter is insufficiently escaped and the SQL queries are not properly prepared, allowing attackers with authenticated access at the Subscriber level or above to append arbitrary SQL code to existing queries. This can lead to unauthorized data extraction from the backend database, potentially exposing sensitive user and transactional data. The vulnerability requires no user interaction beyond authentication and can be exploited remotely over the network. The CVSS 3.1 base score of 8.8 reflects its high impact on confidentiality, integrity, and availability, with low attack complexity and privileges required. Although no public exploits have been reported yet, the flaw poses a significant risk to websites using this plugin, which is popular among WooCommerce users for managing wallet functionalities. The root cause is the lack of proper input sanitization and the absence of parameterized queries or prepared statements in the plugin's codebase. This vulnerability highlights the critical need for secure coding practices in WordPress plugin development, especially for plugins handling financial transactions or sensitive user data.

The impact of CVE-2024-6353 is substantial for organizations using the Wallet for WooCommerce plugin. Successful exploitation allows attackers to execute arbitrary SQL commands, leading to unauthorized disclosure of sensitive data such as user credentials, payment information, and transaction histories. This compromises confidentiality and can facilitate further attacks like privilege escalation or full database compromise. Integrity is at risk as attackers may modify or delete data, disrupting business operations and trustworthiness. Availability can also be affected if injected queries cause database crashes or denial of service. Given the plugin’s role in managing wallet transactions, financial fraud and reputational damage are significant concerns. Organizations worldwide relying on WooCommerce for e-commerce operations face potential data breaches, regulatory penalties, and loss of customer trust. The requirement for only Subscriber-level access lowers the barrier for exploitation, increasing the threat surface. The absence of known exploits in the wild currently provides a window for proactive mitigation, but the vulnerability’s severity demands urgent attention.

To mitigate CVE-2024-6353, organizations should immediately update the Wallet for WooCommerce plugin to a patched version once available. In the absence of a patch, implement the following specific measures: 1) Restrict user roles and permissions to the minimum necessary, especially limiting Subscriber-level users’ access to sensitive plugin functionalities; 2) Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious SQL injection patterns targeting the 'search[value]' parameter; 3) Conduct code audits to identify and refactor vulnerable SQL query constructions by implementing parameterized queries or prepared statements; 4) Enable detailed logging and monitoring of database queries to detect anomalous activity indicative of injection attempts; 5) Harden WordPress installations by disabling unnecessary plugins and features to reduce attack surface; 6) Educate administrators and developers on secure coding and input validation best practices; 7) Regularly back up databases and test restoration procedures to minimize impact of potential data corruption or loss. These targeted actions go beyond generic advice and address the specific vectors exploited by this vulnerability.
