Overview
The CVE-2025-7340 is a critical vulnerability that affects the HT Contact Form Widget For Elementor Page Builder & Gutenberg Blocks & Form Builder plugin for WordPress. This plugin is highly susceptible to arbitrary file uploads, owing to a lack of file type validation in the temp_file_upload function. This vulnerability is present in all versions up to and including 2.2.1. It is of significant concern because it allows unauthenticated attackers to upload arbitrary files to the impacted site’s server, potentially enabling remote code execution.

How the Exploit Works
The vulnerability stems from the absence of file type validation in the ‘temp_file_upload’ function of the affected WordPress plugin. This allows an attacker to upload arbitrary files to the server of the affected site. The lack of authentication requirement means that any attacker with access to the network can potentially exploit this vulnerability. Once the malicious file is uploaded, it could be executed remotely, leading to a potential system compromise or data leakage.
Conceptual Example Code
An example of how this vulnerability might be exploited is shown below. This is a conceptual HTTP request where an attacker uploads a malicious file.
POST /wp-content/plugins/ht-contactform/upload.php HTTP/1.1
Host: target.example.com
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
----WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="malicious.php"
Content-Type: application/php
<?php
// malicious code here
?>

The recommended action to mitigate this vulnerability is to apply the patch provided by the vendor. If the patch cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation, by blocking or alerting on attempts to exploit this vulnerability. In addition, it is always recommended to regularly update and patch all software to ensure the highest level of security.
