CVE-2020-10432Public exploitNetwork attack vector

Authenticated script execution via unfiltered 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 in an administrator's browser. admin/include/check-authority.php copies the final request-URI segment into lang_header, and admin/header.php embeds it in an onclick attribute without filtering or encoding. Superuser, Editor, or Writer access and interaction with a crafted URI are required; injected script can access or alter data available to the browser session.
