AI summary openai / gpt-4o
A critical security flaw has been found in the Optoma CinemaX P2 projector. This device can be controlled by any network device without authentication via its API exposed on TCP port 2345. This could allow attackers to change settings such as volume and network configurations. All organizations using this device should immediately review their network devices and take necessary actions.
The Optoma CinemaX P2 projector's HTTP API is exposed on TCP port 2345, allowing unauthenticated remote control. The affected version is TVOS-04.24.010.04.01. It permits devices on the same network to freely alter projector settings. No specific patch has been provided; however, isolating the projector from the network or enhancing network security is recommended as a workaround. The attack vector is network-based, with low complexity, and requires neither authentication nor user interaction.
