Clickjacking via omitted port 6220 security headers
Published Jun 14, 2022 · Updated Aug 3, 2024
Missing HTTP security headers in Siemens SINEMA Remote Connect Server before 3.0 SP2 allow remote attackers to facilitate clickjacking. The web server on port 6220 omits general response headers that enforce browser-side security controls, leaving client sessions susceptible to UI framing and channel downgrade attacks. Exploitation is unauthenticated over the network but requires user interaction, and the documented consequence is limited to aiding client-side attacks rather than direct server compromise.
