Who is Vulnerable?
Vulnerability Description	Trend Micro ServerProtect offers anti-virus scanning for servers, detecting and removing viruses from files and compressed files. The product provides centralized control over a Windows-based management console for control of virus outbreaks, virus scanning, virus pattern file updates, notifications, and remote installations. A stack-based buffer overflow vulnerability exists in Trend Micro ServerProtect. The vulnerability is due to improper bounds checking of specially crafted messages sent to TMregChange functionality of the service. A remote unauthenticated attacker, with network access to the vulnerable service, could exploit this vulnerability by sending a specially crafted message to the target service and could inject and execute arbitrary code on the target system with System level privileges. In a simple attack case, the affected service process will terminate abnormally when the malicious message is processed. The service will be automatically restarted by a watch-dog process. In a sophisticated attack scenario, where the malicious user is successful in injecting and executing supplied code, the behaviour of the system is dependent on the nature of the injected code. Any code injected into the vulnerable component would execute in the security context of the service process, which is SYSTEM on Windows platforms.
