Background

TeamPass is a password management system that allows users to securely store and share passwords. It is written in PHP and is available as a package on Packagist. The vulnerability in question, identified as CVE-2020-12479, affects TeamPass version 2.1.27.36. This vulnerability allows any authenticated TeamPass user to trigger a PHP file include vulnerability by exploiting a directory traversal flaw in the sources/users.queries.php file.

Vulnerability Detail

The vulnerability arises due to insufficient input validation in the sources/users.queries.php file. By crafting a malicious HTTP request, an authenticated user can manipulate the 'newValue' parameter to perform directory traversal and include arbitrary PHP files. This can lead to remote code execution, allowing an attacker to execute arbitrary code on the server and potentially gain unauthorized access to sensitive information. The severity of this vulnerability is rated as HIGH with a CVSS score of 8.8.
