This flaw enables authenticated attackers to inject and execute persistent JavaScript code within the administrative dashboard. The attack involves bypassing front-end length restrictions by fragmenting malicious payloads across multiple administrative form fields, using techniques like JavaScript comments and template literals to concatenate executable script fragments. These fragments are then rendered in administrative dashboard views, such as index.zhtml, leading to persistent script execution whenever an administrator accesses the affected pages. This vulnerability poses a significant risk to the confidentiality and integrity of the SMS Alert Gateway.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn attacker authenticates to the Taiko AG1000-01A SMS Alert Gateway web configuration interface.\u003c/li\u003e\n\u003cli\u003eThe attacker identifies multiple administrative form fields that allow input.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious JavaScript payload, designed to execute arbitrary commands or exfiltrate sensitive data.\u003c/li\u003e\n\u003cli\u003eThe attacker fragments the payload into smaller chunks, using JavaScript comments (\u003ccode\u003e/* ... */\u003c/code\u003e) and template literals to bypass front-end length restrictions on the form fields.\u003c/li\u003e\n\u003cli\u003eThe attacker submits the fragmented payload across multiple administrative form fields.\u003c/li\u003e\n\u003cli\u003eWhen an administrator accesses a dashboard view such as \u003ccode\u003eindex.zhtml\u003c/code\u003e, the fragmented JavaScript payload is reassembled and executed within the administrator\u0026rsquo;s browser.\u003c/li\u003e\n\u003cli\u003eThe executed JavaScript can perform actions such as stealing administrator cookies, modifying configuration settings, or launching further attacks against the gateway.\u003c/li\u003e\n\u003cli\u003eThe attacker achieves persistent code execution on the SMS Alert Gateway administrative interface, potentially compromising the entire system.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of this stored XSS vulnerability (CVE-2026-9144) could allow an attacker to compromise the Taiko AG1000-01A SMS Alert Gateway.
