Paid Videochat Turnkey Site – HTML5 PPV Live Webcams <= 7.3.23 - Unauthenticated PHP Object Injection

The Paid Videochat Turnkey Site – HTML5 PPV Live Webcams plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 7.3.23 via deserialization of untrusted input. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: Paid Videochat Turnkey Site 7.3.24 closes this, and updating the plugin is the step that ends it.
