CVE-2024-8030 is a critical vulnerability classified under CWE-502 (Deserialization of Untrusted Data) affecting multiple bdthemes WordPress plugins including Ultimate Store Kit Elementor Addons, Woocommerce Builder, EDD Builder, Elementor Store Builder, Product Grid, Product Table, and Woocommerce Slider. The flaw exists due to unsafe deserialization of PHP objects from the _ultimate_store_kit_wishlist cookie, which is user-controllable input. This allows an unauthenticated attacker to inject arbitrary PHP objects into the application. Although the vulnerable plugin itself does not contain a Property Oriented Programming (POP) chain necessary for direct exploitation, if other plugins or themes installed on the same WordPress instance provide such chains, attackers can leverage this vulnerability to perform destructive actions such as arbitrary file deletion, sensitive data disclosure, or remote code execution. The vulnerability is exploitable remotely over the network without any authentication or user interaction, making it highly dangerous. The CVSS v3.1 base score of 9.8 reflects the critical impact on confidentiality, integrity, and availability. No official patches are currently linked, and no exploits have been observed in the wild, but the risk remains high due to the widespread use of these plugins in e-commerce WordPress sites.

The impact of CVE-2024-8030 is severe for organizations using the affected bdthemes plugins in their WordPress e-commerce environments. Successful exploitation can lead to complete compromise of the web server hosting the vulnerable plugins, including arbitrary code execution, deletion of critical files, and exposure of sensitive customer and business data. This can result in operational disruption, data breaches, financial loss, reputational damage, and potential regulatory penalties. Since the vulnerability requires no authentication and no user interaction, attackers can scan and exploit vulnerable sites en masse. The risk is amplified in environments where additional vulnerable plugins or themes provide POP chains, enabling full exploitation. E-commerce platforms relying on these plugins for product display, shopping cart functionality, and user wishlists are particularly at risk, potentially affecting online sales and customer trust.

1. Immediate action should be to update the affected bdthemes plugins to a patched version once available from the vendor. Monitor official bdthemes channels for security updates. 2. In the absence of patches, implement Web Application Firewall (WAF) rules to block or sanitize requests containing the _ultimate_store_kit_wishlist cookie or suspicious serialized PHP objects. 3. Audit and minimize the number of installed plugins and themes, especially those known to contain POP chains, to reduce the attack surface. 4. Employ strict input validation and disable PHP object deserialization where possible, or use safer serialization formats like JSON. 5. Regularly back up website data and configurations to enable recovery in case of compromise. 6. Monitor logs for unusual activity related to cookie manipulation or deserialization errors. 7. Restrict file system permissions to limit the impact of potential file deletion or modification. 8. Conduct penetration testing focusing on deserialization vulnerabilities and chained exploits in the WordPress environment.
