Authenticated script execution via unfiltered request URI
Published Mar 12, 2020 · Updated Aug 4, 2024
Reflected XSS in admin/header.php in Chadha PHPKB Standard Multi-Language 9 allows remote authenticated users to execute script via crafted URIs. The shared header derives lang_header from the final segment of REQUEST_URI and prints it inside an onclick attribute without validation or output encoding. Superuser, Editor, or Writer access is required, and a victim must open the crafted manage-articles.php URL for script to run in the victim's browser context.
