Here is a new exploit that was released about 30 minutes ago. Just thought i'd post it here. I take no credit for this.
| Code: |
#!/usr/bin/perl
# phpBB <= 2.0.17 remote command execution exploit
# need for work:
# 1. PHP 5 < 5.0.5
# 2. register_globals=On
# 3. magic_quotes off
# ------------------------------------------------
# (c)oded by 1dt.w0lf
# RST/GHC
# http://rst.void.ru
# http://ghc.ru
# 03.11.05

Save it to a .pl file and run it in Linux or Cygwin Emulator for Windows. If you dont understand that then read up about how Perl works.

whats the point of copy/paste exploits if don't explain how they work or what they do...
this particular exploit creates a user.. but whats the password ? and how do you input commands?

It would be super if it would work....
Can't locate LWP/UserAgent.pm in @INC (@INC contains: /usr/lib/perl5/5.8.7/i486-linux /usr/lib/perl5/5.8.7 /usr/lib/perl5/site_perl/5.8.7/i486-linux /usr/lib/perl5/site_perl/5.8.7 /usr/lib/perl5/site_perl/5.8.6 /usr/lib/perl5/site_perl/5.8.5 /usr/lib/perl5/site_perl .) at php.pl line 15.
BEGIN failed--compilation aborted at php.pl line 15.
It works only on my localhost, on win xp with active perl installed, but on my servers running linux - no  |

"Done. User r57phpBB2017xp137221 successfully registered."

creates a user, the password will be the same as the usernam. however, i suggest if you don't want things to look wierd then edit the code a little so your username is 20 characters long
i'm not sure what it's useful for. other than you can register without putting in an email address etc...
anyone know what other uses there are... |
