CVE-2024-3211 is a SQL Injection vulnerability classified under CWE-89, found in the Shopping Cart & eCommerce Store plugin for WordPress. The flaw exists due to insufficient escaping and lack of proper parameterized queries in handling the 'productid' attribute of the ec_addtocart shortcode. Authenticated attackers with contributor-level privileges or higher can exploit this vulnerability by injecting additional SQL commands into existing queries. This injection can lead to unauthorized data access, including extraction of sensitive customer or transactional data, modification of database contents, or even deletion of critical records. The vulnerability affects all plugin versions up to and including 5.6.3. The CVSS 3.1 base score of 8.8 reflects the network attack vector, low attack complexity, required privileges (low), no user interaction, and high impacts on confidentiality, integrity, and availability. Although no known exploits are currently reported in the wild, the vulnerability's nature and the popularity of WordPress eCommerce plugins make it a high-risk issue. The lack of patch links suggests that a fix may not yet be publicly available, increasing the urgency for mitigation. Attackers exploiting this flaw can leverage their authenticated access to escalate their impact significantly, making it critical for site administrators to address this promptly.

The potential impact of CVE-2024-3211 is substantial for organizations using the affected WordPress plugin. Successful exploitation can lead to unauthorized disclosure of sensitive customer data, including personal and payment information, which can result in privacy violations and regulatory penalties. Integrity of the database can be compromised, allowing attackers to alter product listings, prices, or transaction records, potentially causing financial loss and reputational damage. Availability may also be affected if attackers delete or corrupt database entries, disrupting eCommerce operations and causing downtime. Since the vulnerability requires only contributor-level authenticated access, it lowers the barrier for exploitation by insiders or compromised accounts. Given the widespread use of WordPress and eCommerce plugins globally, the threat extends to a broad range of organizations, from small businesses to large enterprises. The absence of known public exploits currently reduces immediate risk but does not eliminate the possibility of future attacks, especially as exploit code may be developed and shared rapidly once the vulnerability is widely known.

Organizations should immediately audit their WordPress installations to identify the presence of the Shopping Cart & eCommerce Store plugin and verify the version in use. If an official patch or update is released, it should be applied without delay. In the absence of a patch, administrators should consider temporarily disabling the plugin or restricting contributor-level access to trusted users only. Implementing Web Application Firewall (WAF) rules that detect and block SQL injection patterns targeting the 'productid' parameter can provide interim protection. Additionally, enforcing the principle of least privilege by limiting user roles and permissions reduces the risk of exploitation. Regularly monitoring database logs and application behavior for unusual queries or access patterns can help detect attempted exploitation. Site owners should also ensure that backups are current and tested to enable recovery in case of data corruption or loss. Finally, developers maintaining the plugin should adopt parameterized queries and proper input validation to prevent such vulnerabilities in future releases.
