What is CVE-2022-23178?

An authentication bypass vulnerability exists in the Crestron HD-MD4X2-4K-E HDMI switcher, specifically in version 1.0.0.2159. An attacker can access the administrative web interface without authentication, leading to the disclosure of sensitive user credentials. The interface improperly serves a JSON response containing sensitive fields such as 'uname' and 'upassword', which could enable unauthorized users to gain access and control over the device. This vulnerability highlights the importance of implementing secure access measures in networked devices.
