Who is Vulnerable?
Vulnerability Description	Trend Micro OfficeScan is a centralized virus and security scan management system. It is meant to consolidate the coordination of security scan actions and the management of Trend Micro virus scanner products installed on nodes of an enterprise network. The product is a central command centre for the management of infections or vulnerabilities, as well as information regarding virus events or unusual activity. There exists a buffer overflow vulnerability in Trend Micro's OfficeScan. The flaw is due to a boundary error when handling HTTP requests. An unauthenticated remote attacker can leverage this vulnerability to inject and execute arbitrary code with System level privileges on the target system. In a sophisticated attack case where code injection and execution is successful, the behaviour of the target is entirely dependent on the intended function of the injected code. The code in such a case would execute within the security context of the affected service, normally System. In case if the code execution is not achieved, the CGI process initiated for the session will be terminated abnormally.
