Administrative access via client-side plaintext credentials
Published May 20, 2026 · Updated May 20, 2026
Hard-coded credentials in Taiko AG1000-01A SMS Alert Gateway Rev 7.3 and Rev 8 allow remote attackers to gain administrative access. The validate() function in login.zhtml performs authentication entirely in client-side JavaScript and exposes static plaintext credentials in page source. Network access to the configuration interface is the only reported gate; recovered credentials grant full device administration.
