Vulnerability Note VU#204448
Trend Micro ServerProtect Agent service RPC stack-buffer overflow
OverviewTrend Micro ServerProtect Agent service fails to properly handle RPC requests. This vulnerability may allow a remote, unauthenticated attacker to execute arbitrary code.
I. DescriptionThe Trend Micro ServerProtect Agent service handles RPC Remote Procedure Calls (RPC) using port 3628/tcp. The Trend Micro ServerProtect Agent fails to properly validate RPC requests, possibly allowing a stack-based buffer overflow to occur. A remote, unauthenticated attacker can trigger this overflow vulnerability by sending a specially crafted RPC request to the RPCFN_CopyAUSrc function.
More information can be found in the README file for Security Patch 4.
II. ImpactA remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system.
III. SolutionApply a patch
Trend Micro has addressed these vulnerabilities with Security Patch 4.
Restrict Access to the Trend Micro ServerProtect Agent
Until the patch can be applied you may wish to block access to the vulnerable software from outside your network perimeter, specifically by blocking access to the ports used by the Trend Micro ServerProtect Agent service (3628/tcp). This will limit your exposure to attacks. However, blocking at the network perimeter would still allow attackers within the perimeter of your network to exploit the vulnerability. The use of host-based firewalls in addition to network-based firewalls can help restrict access to specific hosts within the network. It is important to understand your network's configuration and service requirements before deciding what changes are appropriate.
