Summary
Spacelabs Healthcare Sentinel versions 10.5.x and higher, and 11.x.x before 11.6.0, contain an unauthenticated remote code execution vulnerability through a deprecated .NET Remoting HTTP channel on port 8989. Attackers can read/write arbitrary files and deploy ASPX webshells.
Risk Assessment
An attacker can gain full control of the Sentinel system by executing code in the IIS context, potentially compromising the confidentiality and integrity of medical data.
Recommendation
Upgrade Spacelabs Healthcare Sentinel to version 11.6.0 or later. Ensure port 8989 is not network-accessible unless absolutely necessary.
Original NVD description (English source)
Spacelabs Healthcare Sentinel versions 10.5.x and higher and 11.x.x before 11.6.0 contain an unauthenticated remote code execution vulnerability through a deprecated .NET Remoting HTTP channel exposed on port 8989 that allows attackers to perform arbitrary file read and write operations by supplying valid .NET URI endpoints. Attackers can write ASPX webshells to the IIS wwwroot directory to achieve unauthenticated remote code execution on the system. Port 8989 is not exposed in a default Sentinel installation; exploitation requires that the .NET Remoting port has been explicitly made network-accessible through deliberate configuration or network policy changes.
