Authenticated script execution via unencoded request URI
Published Mar 12, 2020 · Updated Aug 4, 2024
Reflected XSS in Chadha PHPKB Standard Multi-Language 9 allows remote authenticated users to execute script through a crafted add-category.php URI. The check-authority.php code takes the final segment of REQUEST_URI as lang_header, and admin/header.php prints it into an onclick handler without validation or encoding. An Editor, Writer, or Superuser must open the crafted administration-panel URI; the payload then runs in that user's browser security context.
