Browser script execution via unescaped skinName reflection
Published Aug 23, 2024 · Updated Aug 23, 2024
Cross-site scripting in ThinkGem JeeSite 5.3 allows remote attackers to run script in a user's browser through the login page. The /js/a/login handler reflects the skinName parameter into generated page content without neutralizing browser-interpreted input. The endpoint requires no authentication, but a victim must load the crafted response; execution remains bounded to the victim's browser context.
