CVE-2024-3608 identifies a missing authorization vulnerability (CWE-862) in the Product Designer plugin for WordPress, specifically in the product_designer_ajax_delete_attach_id() function. This function lacks proper capability checks, allowing unauthenticated attackers to invoke it and delete arbitrary attachments managed by the plugin. The vulnerability affects all versions up to and including 1.0.33. Since the function is accessible via AJAX, attackers can remotely trigger deletion requests without authentication or user interaction, making exploitation straightforward. The vulnerability primarily impacts availability by enabling unauthorized deletion of files, which could disrupt website content or functionality relying on those attachments. No known public exploits have been reported yet, but the ease of exploitation and lack of authentication requirements make it a significant risk. The CVSS v3.1 base score is 5.3 (medium), reflecting network attack vector, low attack complexity, no privileges required, no user interaction, and an impact limited to availability loss. The absence of patches at the time of disclosure means organizations must rely on interim mitigations. Given the widespread use of WordPress and the popularity of plugins for e-commerce and product customization, this vulnerability could affect many websites globally, especially those using the Product Designer plugin.

The primary impact of CVE-2024-3608 is unauthorized deletion of attachments, which can lead to loss of media files or other critical content managed by the Product Designer plugin. This availability impact can disrupt website operations, degrade user experience, and potentially cause business interruptions, especially for e-commerce sites relying on product images or custom designs. Although the vulnerability does not directly affect confidentiality or integrity of data beyond deletion, the loss of attachments can indirectly harm data integrity and trustworthiness of the website content. The ease of exploitation without authentication or user interaction increases the risk of automated or mass exploitation attempts. Organizations worldwide using this plugin face potential service disruption and reputational damage if attackers leverage this flaw. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, as attackers may develop exploits rapidly after disclosure.

Until an official patch is released, organizations should implement specific mitigations to reduce risk: 1) Restrict access to the AJAX endpoint product_designer_ajax_delete_attach_id() by configuring web application firewalls (WAFs) or server-level access controls to allow only trusted IP addresses or authenticated users. 2) Disable or remove the Product Designer plugin if it is not essential to reduce attack surface. 3) Monitor web server and application logs for suspicious AJAX requests targeting the delete_attach_id function to detect potential exploitation attempts. 4) Implement regular backups of website content and attachments to enable recovery from unauthorized deletions. 5) Once patches become available, apply them promptly to restore proper authorization checks. 6) Educate site administrators about the vulnerability and encourage minimizing plugin usage to trusted and actively maintained components. These targeted steps go beyond generic advice by focusing on access control and monitoring specific to the vulnerable function.
