Summary
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. Unauthenticated attackers with network access can recover administrative credentials directly from the client-side validate() function to obtain full administrative access to the device.
