CVE-2024-12562: CWE-502 Deserialization of Untrusted Data in WP Sharks s2Member Pro
The s2Member Pro plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 241216 via deserialization of untrusted input from the 's2member_pro_remote_op' vulnerable parameter. This makes it possible for unauthenticated attackers 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-2024-12562 is a PHP Object Injection vulnerability in the s2Member Pro WordPress plugin (up to version 241216) caused by unsafe deserialization of untrusted input from the 's2member_pro_remote_op' parameter. This vulnerability allows unauthenticated attackers to inject PHP objects. Exploitation depends on the presence of a gadget chain (POP chain) in the plugin or other installed components, which could lead to arbitrary file deletion, sensitive data disclosure, or remote code execution. The vulnerability is rated critical with a CVSS 3.1 score of 9.8.
Potential Impact
Successful exploitation can lead to full compromise of the affected WordPress site, including deletion of arbitrary files, exposure of sensitive information, and remote code execution. The vulnerability affects confidentiality, integrity, and availability. However, exploitation requires a suitable POP chain in the environment, which is not present in the plugin alone.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, administrators should consider disabling or restricting access to the vulnerable parameter if possible and review installed plugins and themes for potential gadget chains. Monitor vendor channels for updates and apply patches promptly once available.
