Trend Micro ServerProtect Buffer Overflows in ServerProtect Modules Let Remote Users Execute Arbitrary Code
SecurityTracker Alert ID:  1018594
SecurityTracker URL:  http://securitytracker.com/id/1018594
CVE Reference:   CVE-2007-4218, CVE-2007-4219, CVE-2007-4731   (Links to External Site)
Updated:  Dec 18 2007
Original Entry Date:  Aug 22 2007
Impact:   Execution of arbitrary code via network, Root access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 5.58 Security Patch 3 and prior
Description:   A vulnerability was reported in Trend Micro ServerProtect. A remote user can execute arbitrary code on the target system.

A remote user can send specially crafted data to the ServerProtect service (SpntSvc.exe) on TCP port 5168 to trigger one of several buffer overflows and execute arbitrary code on the target system. The code will run with System level privileges.

The RPCFN_ENG_NewManualScan(), RPCFN_ENG_TimedNewManualScan(), and RPCFN_SetComputerName() functions in the StRpcSrv.dll library are affected.

The RPCFN_CMON_SetSvcImpersonateUser() and RPCFN_OldCMON_SetSvcImpersonateUser() functions in the Stcommon.dll library are affected.

The ENG_TakeActionOnAFile() and RPCFN_ENG_AddTaskExportLogItem() functions in the Eng50.dll library are affected.

The NTF_SetPagerNotifyConfig() function in the Notification.dll library is affected.

The RPCFN_SYNC_TASK() function is affected [CVE-2007-4219].

A remote user can send specially crafted data to TCP port 5005 to trigger a stack overflow and execute arbitrary code on the target system. The code will run with System level privileges.

The TMregChange() function is affected [CVE-2007-4731].

A remote user can send specially crafted data to the ServerProtect Agent service on TCP port 3628 to trigger a buffer overflow and execute arbitrary code on the target system. The code will run with System level privileges.

The RPCFN_CopyAUSrc() function is affected.

The vendor was notified on June 14, 2007 and July 17, 2007.

Code Audit Labs and other researchers reported these vulnerabilities via iDefense. Jun Mao of iDefense Labs also reported these vulnerabilities. Sebastian Apelt reported one of these vulnerabilities via TippingPoint. Eric Detoisien reported one of these vulnerabilities via TippingPoint.

Impact:   A remote user can execute arbitrary code on the target system with System level privileges
Solution:   The vendor has issued a fix (Security Patch 4 - Build 1185).

Trend Micro ServerProtect Multiple Buffer Overflow Vulnerabilities

iDefense Security Advisory 08.21.07
http://labs.idefense.com/intelligence/vulnerabilities/
Aug 21, 2007

I. BACKGROUND

Trend Micro Inc.'s ServerProtect is an anti-virus software for Microsoft
Windows and Novell NetWare servers. It enables network administrators to
manage multiple deployments from a single management console. For more
information, please visit vendor's website at the following URL.

http://us.trendmicro.com/us/products/enterprise/serverprotect-for-microsoft-windows/index.html

II. DESCRIPTION

Remote exploitation of multiple buffer overflow vulnerabilities in Trend
Micro Inc.'s ServerProtect anti-virus software could allow attackers to
execute arbitrary code with system level privilege.

The Trend ServerProtect service (SpntSvc.exe) handles RPC requests on
TCP port 5168 with interface uuid 25288888-bd5b-11d1-9d53-0080c83a5c2c.
This service utilizes the StRpcSrv.dll, Stcommon.dll, Eng50.dll and
Notification.dll libraries to service various RPC requests.

Three buffer overflows exist with the StRpcSrv.dll library. The first
two vulnerabilities exist within the RPCFN_ENG_NewManualScan and
RPCFN_ENG_TimedNewManualScan functions. These functions copy
user-supplied data into a fixed-size heap buffer without performing
proper bounds checking. The third problem exists within the
RPCFN_SetComputerName function. This function copies user-supplied data
into a fixed-size stack buffer using the MultiByteToWideChar() function
without correctly specifying the output buffer length.

Two stack-based buffer overflows exist within the Stcommon.dll library.
These problems specifically exist within the
RPCFN_CMON_SetSvcImpersonateUser and
RPCFN_OldCMON_SetSvcImpersonateUser functions. These functions copy
user-supplied data into a fixed-size stack buffer without performing
proper bounds checking.

Two buffer overflows exist within the Eng50.dll library. These two
issues exist within the ENG_TakeActioinOnAFile and
RPCFN_ENG_AddTaskExportLogItem functions. Both of these functions copy
user-supplied data into fixed-size buffers without performing proper
bounds checking. The ENG_TakeActioinOnAFile function uses a buffer
stored on the heap as the destination, where as the
RPCFN_ENG_AddTaskExportLogItem function uses a buffer stored in stack
memory.

A stack-based buffer overflow exists within the Notification.dll
library. This vulnerability specifically exists in the
NTF_SetPagerNotifyConfig function. This function copies user-supplied
data into a fixed-size stack buffer without performing proper bounds
checking.

The Trend ServerProtect Agent service handles RPC requests on TCP port
3628 with interface uuid 25288888-bd5b-11d1-9d53-0080c83a5c2c. A
stack-based buffer overflow has been found to exist within the
RPCFN_CopyAUSrc function. This function copies user-supplied data into
a fixed-size stack buffer.

III. ANALYSIS

Exploitation allows attackers to execute arbitrary code with system
level privilege.

Exploitation requires that attackers send specially crafted RPC requests
to the Trend ServerProtect or Trend ServerProtect Agent services.

IV. DETECTION

iDefense has confirmed the existence of these vulnerabilities in
ServerProtect for Windows 5.58 Build 1176 (Security Patch 3). Previous
versions, as well as versions for other platforms, are suspected to be
vulnerable.

V. WORKAROUND

iDefense is currently unaware of any workarounds for this issue.

VI. VENDOR RESPONSE

Trend Micro has addressed these vulnerabilities with the release of
Security Patch 4 for ServerProtect. For more information consult the
release notes at the following URL.

http://www.trendmicro.com/ftp/documentation/readme/spnt_558_win_en_securitypatch4_readme.txt

VII. CVE INFORMATION

The Common Vulnerabilities and Exposures (CVE) project has assigned the
name CVE-2007-4218 to this issue. This is a candidate for inclusion in
the CVE list (http://cve.mitre.org/), which standardizes names for
security problems.
