## Affected

- Taiko Network Communications Pte Ltd. AG1000-01A SMS Alert Gateway: Rev 7.3, Rev 8, UM-AG1000\_R7.2

## Description

Taiko AG1000-01A SMS Alert Gateway Rev 7.3 and Rev 8 contains an authentication bypass vulnerability in the embedded web configuration interface that allows unauthenticated attackers to access internal application pages without any session management or server-side authentication checks. Attackers with network access can directly request internal resources such as index.zhtml, point.zhtml, and log.shtml to gain full administrative read and write access, enabling unauthorized modification of alarm routing, device configuration, and disruption of monitoring and control functions.
