Traffic tampering via missing HSTS header
Published Jul 16, 2026 · Updated Jul 16, 2026
Missing HSTS enforcement in HCL DFX Analytics 3.0 and earlier allows remote authenticated users to downgrade HTTPS connections to HTTP. The web response path omits the Strict-Transport-Security header, so clients are not instructed to require HTTPS on later requests. Exploitation requires low-privileged access and a man-in-the-middle position; it permits traffic modification, with no reported disclosure or service interruption.
