Vulnerability details

The Optoma CinemaX P2 projector (firmware TVOS-04.24.010.04.01, Android 8.0.0) exposes an HTTP API on TCP port 2345 that allows full unauthenticated remote control of the device. The API supports both reading configuration (74 endpoints) and writing/modifying settings including volume, mute,…

T1133 External Remote Services Persistence
Adversaries may leverage external-facing remote services to initially access and/or persist within a network.

Why these techniques?

Unauthenticated exposed HTTP control API directly enables remote exploitation of a network-accessible service (T1190) and abuse of the device as an external remote service (T1133).

Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

AC-1 Policy and Procedures
addresses: CWE-285

Documented procedures facilitate correct implementation and ongoing management of authorization decisions.

AC-13 Supervision and Review — Access Control
addresses: CWE-285

Periodic reviews identify and correct flaws in authorization decisions or enforcement.

AC-14 Permitted Actions Without Identification or Authentication
addresses: CWE-285

The control's documentation requirement reduces improper authorization by ensuring only mission-justified actions bypass authentication.

AC-16 Security and Privacy Attributes
addresses: CWE-285

Establishing permitted attributes and values, plus auditing changes, ensures authorization decisions are based on correctly managed policy data.

AC-17 Remote Access
addresses: CWE-285

Explicitly mandates authorizing remote access types before permitting connections, directly mitigating improper authorization.

AC-18 Wireless Access
addresses: CWE-285

The control explicitly requires authorization of each wireless access type prior to permitting connections.

AC-19 Access Control for Mobile Devices
addresses: CWE-285

Mandating explicit authorization of mobile device connections reduces the risk of improper authorization decisions for system access.

AC-2 Account Management
addresses: CWE-285

Specifying access authorizations for each account and requiring approvals for account requests enforces proper authorization decisions.
