CVE-2024-33328Public exploitNetwork attack vector

Browser script execution via unneutralized pageId parameter

Published Jun 26, 2024 · Updated Mar 25, 2025

Reflected XSS in LumisXP 15.0.x through 16.1.x allows remote attackers to run script in a user's browser through pageId. The main.jsp endpoint processes the URL-decoded pageId value during page generation without neutralizing script-capable input. No authentication is required, but a user must follow a crafted URL; the resulting script executes within that user's LumisXP origin.
