Administrator script execution via unescaped AJAX parameter
Published Jul 17, 2023 · Updated Oct 30, 2024
Reflected XSS in Liquid Web Restrict Content before 3.2.3 allows remote attackers to execute scripts in an administrator's browser. The rcp_ajax_dismissed_notice_handler function returns attacker-controlled POST parameter a without sufficient sanitization or output escaping. Exploitation requires an authenticated administrator to submit the crafted request, exposing that session to script-controlled actions.
