Official 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. Attackers can bypass front-end length restrictions using JavaScript comments and template literals to concatenate executable script fragments that are rendered in administrative dashboard views such as index.zhtml, resulting in persistent script execution within administrative sessions.

The underlying weakness: Improper Neutralization of Input During Web Page Generation

The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.

How developers prevent this class of flaw

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. Examples of libraries and frameworks that make it easier to generate properly encoded output include Microsoft's Anti-XSS library, the OWASP ESAPI Encoding module, and Apache Wicket.
  • Understand all the potential areas where untrusted inputs can enter your software: parameters or arguments, cookies, anything read from the network, environment variables, reverse DNS lookups, query results, request headers, URL components, e-mail, files, filenames, databases, and any external systems that provide data to the application. Remember that such inputs may be obtained indirectly through API calls.
  • For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
