Assigner: Wordfence

Description
The Gravity Forms plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the legacy chunked upload mechanism in all versions up to, and including, 2.9.21.1. This is due to the extension blacklist not including .phar files, which can be uploaded through the chunked upload mechanism. This makes it possible for unauthenticated attackers to upload executable .phar files and achieve remote code execution on the server, granted they can discover or enumerate the upload path. In order for an attacker to achieve RCE, the web server needs to be set up to process .phar file as PHP via file handler mapping or similar.

Executive Summary

This vulnerability exists in the Gravity Forms plugin for WordPress, where the legacy chunked upload mechanism lacks proper file type validation. Specifically, the extension blacklist does not include .phar files, allowing unauthenticated attackers to upload executable .phar files. If the web server is configured to process .phar files as PHP, attackers can achieve remote code execution by discovering or enumerating the upload path.

Impact Analysis

This vulnerability can allow unauthenticated attackers to upload and execute malicious .phar files on the server, potentially leading to remote code execution. This can result in full compromise of the affected server, including unauthorized access, data theft, data modification, or disruption of services.

Mitigation Strategies

To mitigate this vulnerability, immediately update the Gravity Forms plugin to a version later than 2.9.21.1 where the issue is fixed. Additionally, review and restrict file upload mechanisms to ensure proper file type validation, especially blocking .phar files. Also, verify your web server configuration to prevent processing of .phar files as PHP to reduce risk of remote code execution.
