Since port 8989 is not exposed by default, ensure that this port is not accessible from untrusted networks. If the .NET Remoting HTTP channel on port 8989 is not required, disable or block access to this port to mitigate risk. Monitor vendor communications for any forthcoming official fixes or updates.
Description
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.
