Description

Taiko AG1000-01A SMS Alert Gateway Rev 7.3 and Rev 8 contains a stored cross-site scripting vulnerability in the embedded web configuration interface that allows authenticated attackers to execute persistent JavaScript by fragmenting malicious payloads across multiple administrative form fields.
