Microsoft Server Message Block (SMB) Remote Exploit (MS05-011)

CODE

/*
* Windows SMB Client Transaction Response Handling
*
* MS05-011
* CAN-2005-0045
*
* This works against Win2k
*
* cybertronic[at]gmx[dot]net
* http://www.livejournal.com/users/cybertronic/
*
* usage:
* gcc -o mssmb_poc mssmb_poc.c
* ./mssmb_poc
*
* connect via \\ip
* and hit the netbios folder!
*
* ***STOP: 0x00000050 (0xF115B000,0x00000001,0xFAF24690,
* 0x00000000)
* PAGE_FAULT_IN_NONPAGED_AREA
*
* The Client reboots immediately
*
* Technical Details:
* -----------------
*
* The driver MRXSMB.SYS is responsible for performing SMB
* client operations and processing the responses returned
* by an SMB server service. A number of important Windows
* File Sharing operations, and all RPC-over-named-pipes,
* use the SMB commands Trans (25h) and Trans2 (32h). A
* malicious SMB server can respond with specially crafted
* Transaction response data that will cause an overflow
* wherever the data is handled, either in MRXSMB.SYS or
* in client code to which it provides data. One example
* would be if the
*
* file name length field
*
* and the
*
* short file name length field
*
* in a Trans2 FIND_FIRST2 response packet can be supplied
* with inappropriately large values in order to cause an
* excessive memcpy to occur when the data is handled.
* In the case of these examples an attacker could leverage
* file:// links, that when clicked by a remote user, would
* lead to code execution.
