Summary

The Drag-and-Drop Multiple File Upload Contact Form 7 plugin for WordPress prior to version 1.3.3.3 is susceptible to a vulnerability that allows attackers to exploit unrestricted file uploads. Specifically, the issue arises when the supported types are incorrectly set to accept files like php% without proper validation. This misconfiguration permits an attacker to upload a malicious .php% file, potentially leading to remote code execution on the server. Website owners using this plugin should update to the latest version to mitigate the risk.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
