Exposure of WSDL File Containing Sensitive Information

WSDL (Web Services Description Language) files define web service endpoints, available operations, and data structures. When exposed publicly, these files can reveal sensitive information, such as:

  • Endpoints & Methods – Allowing attackers to map out service functionalities.

  • Authentication & Security Details – Exposing security mechanisms (e.g., API keys, credentials).

  • Internal System Information – Revealing database schemas, internal endpoints, or debugging messages.
