Technical details
HCL DFXAnalytics (version 3.0 and below) is vulnerable to account takeover via response manipulation (CWE-294). A remote attacker with low privileges can intercept and alter HTTP responses from the server before they reach the client-side application. By modifying the authentication or authorization logic contained within these responses, the attacker can bypass security controls to gain unauthorized access to targeted user accounts. This attack requires high complexity (AC:H) and user interaction (UI:R), typically involving a man-in-the-middle (MitM) position or similar interception capability. HCL has addressed this in their security bulletin KB0131787.
