Executive brief
HCL iControl, a business process monitoring and control platform, is affected by a vulnerability where the system reveals too much technical information in its error messages. Instead of showing a simple error to the user, the application displays internal details such as server names, specific request data, and login status. While this does not allow an attacker to take over the system directly, it provides them with a roadmap of the internal architecture that could be used to plan more sophisticated attacks.
Technical details
HCL iControl versions 4.3.0 and 4.4.0 are vulnerable to CWE-209 (Generation of Error Message Containing Sensitive Information). The application fails to sanitize API responses, leading to the exposure of raw server-side error messages to the client-side interface. These messages contain sensitive technical metadata including internal endpoint names, request parameters, specific error codes, and the current authentication status of the session. An unauthenticated remote attacker can trigger these errors to gain reconnaissance data about the internal API structure and environment configuration. The vulnerability is rated low severity due to the high attack complexity and the fact that it only results in partial information disclosure without direct impact on integrity or availability.
