Description


Some vulnerabilities have been reported in Trend Micro ServerProtect, which can be exploited by malicious people to compromise a vulnerable system.

1) An integer overflow error within the RPCFN_SYNC_TASK function in StRpcSrv.dll can be exploited to cause a heap-based buffer overflow via a specially crafted RPC request to SpntSvc.exe on default port 5168/TCP.

2) Boundary errors within the RPCFN_ENG_NewManualScan, RPCFN_ENG_TimedNewManualScan, and RPCFN_SetComputerName functions in StRpcSrv.dll can be exploited to cause stack-based buffer overflows via specially crafted RPC requests to SpntSvc.exe on default port 5168/TCP.

3) Boundary errors within the RPCFN_CMON_SetSvcImpersonateUser and RPCFN_OldCMON_SetSvcImpersonateUser functions in Stcommon.dll can be exploited to cause stack-based buffer overflows via specially crafted RPC requests to SpntSvc.exe on default port 5168/TCP.

4) Boundary errors within the RPCFN_ENG_TakeActionOnAFile and RPCFN_ENG_AddTaskExportLogItem functions in Eng50.dll can be exploited to cause heap- and stack-based buffer overflows via specially crafted RPC requests to SpntSvc.exe on default port 5168/TCP.

5) A boundary error within the NTF_SetPagerNotifyConfig function in Notification.dll can be exploited to cause a stack-based buffer overflow via a specially crafted RPC request to SpntSvc.exe on default port 5168/TCP.

6) A boundary error within the RPCFN_CopyAUSrc function in the Trend ServerProtect Agent service can be exploited to cause a stack-based buffer overflow via a specially crafted RPC request sent to default port 3628/TCP.

7) Boundary errors within the RPCFN_EVENTBACK_DoHotFix and CMD_CHANGE_AGENT_REGISTER_INFO in earthagent.exe can be exploited to cause buffer overflows.

8) A boundary error within the TMregChange function in TMReg.dll can be exploited to cause a stack-based buffer overflow via a specially crafted RPC request with subcode "\x15\x00\x00\x00" sent to default port 5005/TCP.

9) The SpntSvc.exe service exposes multiple insecure methods in StRpcSrv.dll, which can be exploited to manipulate the file system by sending RPC requests to default port 5168/TCP.

Successful exploitation of the vulnerabilities allows execution of arbitrary code.

The vulnerabilities are reported in ServerProtect for Windows version 5.58 Build 1176. Other versions may also be affected.
