Vulnerability Description	Symantec Systems Center provides centralized systems and policy management for Norton Antivirus Enterprise Solution across multiple Windows NT and NetWare networks. The Symantec Systems Center includes an optional component called the Alert Management System (AMS2). An arbitrary command execution vulnerability exists in Symantec Alert Management System (AMS2) service shipped with multiple Symantec products. The AMS service starts an alert handler service, HNDLRSVC, that listens for commands from the AMS server but does not perform proper authentication checks before executing such commands. Remote unauthenticated attackers can exploit this vulnerability by sending a crafted packet to the target service and execute arbitrary programs with the SYSTEM privileges.
