Improper Restriction of Operations within the Bounds of a Memory Buffer


Severity High
Score 10/10


Multiple buffer overflows in the ServerProtect service (SpntSvc.exe) in Trend Micro ServerProtect for Windows before 5.58 Security Patch 4 allow remote attackers to execute arbitrary code via certain RPC requests to certain TCP ports that are processed by the (1) RPCFN_ENG_NewManualScan, (2) RPCFN_ENG_TimedNewManualScan, and (3) RPCFN_SetComputerName functions in (a) StRpcSrv.dll; the (4) RPCFN_CMON_SetSvcImpersonateUser and (5) RPCFN_OldCMON_SetSvcImpersonateUser functions in (b) Stcommon.dll; the (6) RPCFN_ENG_TakeActionOnAFile and (7) RPCFN_ENG_AddTaskExportLogItem functions in (c) Eng50.dll; the (8) NTF_SetPagerNotifyConfig function in (d) Notification.dll; or the (9) RPCFN_CopyAUSrc function in the (e) ServerProtect Agent service.

CWE-119 - Buffer Overflow

Buffer overflow attacks involve data transit and operations exceeding the restricted memory buffer, thereby corrupting or overwriting data in adjacent memory locations. Such overflow allows the attacker to run arbitrary code or manipulate the existing code to cause privilege escalation, data breach, denial of service, system crash and even complete system compromise. Given that languages such as C and C++ lack default safeguards against overwriting or accessing data in their memory, applications utilizing these languages are most susceptible to buffer overflows attacks.
