Welcart e-Commerce < 2.9.6 - Admin+ PHP Object Injection

Description

The plugin is vulnerable to PHP Object Injection in all versions up to 2.9.5 (inclusive) via deserialization of untrusted input in the welcart_confirm_check_ajax function. This makes it possible for administrators to inject a PHP Object. No POP chain is present in the vulnerable plugin. 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.
