Reflected XSS via unescaped login input
Published May 7, 2021 · Updated Aug 3, 2024
Reflected XSS in LivingLogic XIST4C 0.89.0 through 0.107.7 allows remote attackers to run script in a victim's browser via a crafted link. The login.htm, login.wihtm, and login-form.htm handlers place user-controlled request input into generated page output without neutralization. A victim must open the attacker-supplied link; the script then runs in the XIST4C origin and can read or alter data available to that session.
