Vulnerability Overview

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.

Technical Analysis

REMEDIATION: Update to version 250214, or a newer patched version --- IDENTIFIER: CWE-502 (Deserialization of Untrusted Data) The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
