CVE-2024-12721: CWE-502 Deserialization of Untrusted Data in webbuilder143 Custom Product tabs for WooCommerce
The Custom Product Tabs For WooCommerce plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.2.4 via deserialization of untrusted input from the 'wb_custom_tabs' parameter. This makes it possible for authenticated attackers, with Shop Manager-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
AI Analysis
Technical Summary
CVE-2024-12721 is a deserialization of untrusted data vulnerability (CWE-502) in the Custom Product Tabs For WooCommerce WordPress plugin (versions up to 1.2.4). The vulnerability arises from unsafe deserialization of the 'wb_custom_tabs' parameter, allowing authenticated users with Shop Manager privileges or higher to inject PHP objects. While the plugin does not include a known POP chain for exploitation, the presence of additional plugins or themes with gadget chains could enable severe impacts such as arbitrary file deletion, data leakage, or remote code execution. The CVSS 3.1 base score is 7.2, indicating high severity with network attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability.
Potential Impact
An attacker with Shop Manager-level access or higher can exploit this vulnerability to inject PHP objects via deserialization. Without a POP chain in the plugin itself, direct exploitation is limited, but if other installed plugins or themes provide a suitable POP chain, the attacker could delete arbitrary files, access sensitive information, or execute arbitrary code. This elevates the risk to the confidentiality, integrity, and availability of the affected WordPress site.
Mitigation Recommendations
No official patch or fix is currently available for this vulnerability. Administrators should monitor the vendor's advisory for updates. In the meantime, restrict Shop Manager-level access to trusted users only and consider disabling or removing the vulnerable plugin if possible. Review installed plugins and themes for potential POP chains that could be leveraged in conjunction with this vulnerability. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
