CVE-2022-38080Network attack vector

Authenticated browser script execution via reflected input

Published Aug 24, 2022 · Updated Aug 3, 2024

Reflected XSS in Exment 4.4.2 and earlier for PHP 7 and 5.0.2 and earlier for PHP 8 allows remote authenticated users to execute scripts. Published vendor and JVN materials identify affected screens but do not disclose the input parameter or output operation that reflects it. Exploitation requires a logged-in attacker and a separate user to open the crafted request, where script execution is confined to that user's browser session.
