ZDI-07-077: Trend Micro ServerProtect StRpcSrv.dll Insecure Method 
Exposure Vulnerability
http://www.zerodayinitiative.com/advisories/ZDI-07-077.html
December 17, 2007

- -- CVE ID:


- -- Affected Vendor:
Trend Micro

- -- Affected Products:
ServerProtect v5.58

- -- TippingPoint(TM) IPS Customer Protection:
TippingPoint IPS customers have been protected against this
vulnerability by Digital Vaccine protection filter ID 5126. 
For further product information on the TippingPoint IPS:

    http://www.tippingpoint.com 

- -- Vulnerability Details:
These vulnerabilities allow attackers to execute arbitrary code on
vulnerable installations of Trend Micro ServerProtect. Authentication
is not required to exploit these vulnerabilities.

The specific flaw exists in the SpntSvc.exe daemon, bound by default on
TCP port 5168 and exposing the following DCE/RPC interface through
TmRpcSrv.dll:

    /* opcode: 0x00, address: 0x65741030 */
    error_status_t sub_65741030 (
        [in] handle_t arg_1,
        [in] long arg_2,
        [in][size_is(arg_4)] byte arg_3[],
        [in] long arg_4,
        [out][size_is(arg_6)] byte arg_5[],
        [in] long arg_6
    );

Various sub-functions from StRpcSrv.dll are exposed in this interface
and allow for full file system access that can be trivially leveraged
to executed arbitrary code.
