Name of the Vulnerable Software and Affected Versions: TVT DVR Cross Web Server (affected versions not specified) Description: An OS command injection issue exists in the custom HTTP service called "Cross Web Server" that listens on TCP ports 81 and 82. The web interface fails to sanitize input in the URI path passed to the language extraction functionality. When the server processes a request to "/language/[lang]/index.html", it uses the `[lang]` input unsafely in a tar extraction command without proper escaping. This allows an unauthenticated remote attacker to inject shell commands and achieve arbitrary command execution as root. Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.

The issue is related to insufficient access restrictions in the Windows SMB Witness Service, which can be exploited by a remote attacker to elevate their privileges. This can affect the system.

The issue is related to incorrect code generation management in the Hyper-V component of the Windows operating system. It allows a remote attacker to execute arbitrary code. The problem can be exploited for remote code execution or to cause a denial-of-service state. The vulnerability affects the Hyper-V virtual network switch driver (vmswitch.sys).
