CVE-2020-10387Public exploitNetwork attack vector

Authenticated file disclosure via unchecked download path

Published Mar 12, 2020 · Updated Aug 4, 2024

Path traversal in PHPKB Standard Multi-Language 9 allows remote authenticated users to download arbitrary server files through admin/download.php. The endpoint appends the GET file value to a backup directory and passes the resulting path to file_get_contents without validation, allowing ../ sequences to escape that directory. Superuser access is required, and successful exploitation reads files available to the web-server process, including the PHPKB configuration file.
