Unauthenticated access via manipulated authentication responses
Published Jul 16, 2026 · Updated Jul 16, 2026
Authentication bypass in HCL Software DFX Server Solution 2.5 and earlier allows remote attackers to access the application without credentials. The flaw is reached by intercepting and altering a server authentication response; HCL has not identified the affected handler or validation error. No credentials or user interaction are required; exploitation exposes application data and allows limited modification without interrupting service.
