Who is Vulnerable?
Vulnerability Description	Symantec Veritas Storage Foundation for Windows (SFW) is a storage management suite. With a set of networks services and client agents, the product provides solution for online heterogeneous storage management. One of the services installed by SFW is the Veritas Scheduler Service, implemented in executable binary file VxSchedService.exe. This service listens on TCP port 4888 by default. A security bypass vulnerability exists in Symantec Veritas Storage Foundation Scheduler Service. The vulnerability is due to improper handling of NTLMSSP authentication. Remote unauthenticated attackers could exploit this vulnerability by using NULL NTLMSSP authentication to manipulate snapshots, their schedules, and run other potentially unsafe disk manipulation commands on the target server. Successful exploitation could lead to arbitrary code execution in the security context of the SYSTEM user. An attack targeting this vulnerability can result in authentication bypass and command execution to the target system. In an attack case where command execution is successful, the behaviour of the target is entirely dependent on the intended function of the executed commands. The code in such a case would execute within the security context of the running process, normally System.
