Trend Micro ServerProtect AgRpcCln.dll buffer overflow

serverprotect-agrpccln-bo (34162) The risk level is classified as HighHigh Risk

Description:

Trend Micro ServerProtect is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the CAgRpcClient::CreateBinding() function in the AgRpcCln.dll library. By sending a specially-crafted RPC request to TCP port 5168, a remote attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges.

  • CVE-2007-2508: Multiple stack-based buffer overflows in Trend Micro ServerProtect 5.58 before Security Patch 2 Build 1174 allow remote attackers to execute arbitrary code via crafted data to (1) TCP port 5168, which triggers an overflow in the CAgRpcClient::CreateBinding function in the AgRpcCln.dll library in SpntSvc.exe; or (2) TCP port 3628, which triggers an overflow in EarthAgent.exe. NOTE: both issues are reachable via TmRpcSrv.dll.
