A cross-site scripting (XSS) vulnerability in Zyxel NBG-418N v2 firmware versions prior to V1.00(AARP.13)C0, which could allow an attacker to store malicious scripts in the Logs page of the GUI on a vulnerable device. A successful XSS attack could force an authenticated user to execute the stored malicious scripts and then result in a denial-of-service (DoS) condition when the user visits the Logs page of the GUI on the device.
