## Description

Taiko AG1000-01A SMS Alert Gateway Rev 7.3 and Rev 8 contains a hard-coded credential vulnerability in the embedded web configuration interface where authentication is implemented entirely in client-side JavaScript in login.zhtml, exposing static plaintext credentials in the page source.
