Phpnuke is unique software, because there is very big number of
the various derivations, versions, editions, patches, etc...
And if you will try to contact with Francisco Burzi himself, then you
just will not get any answer. So, if i will discover some major security
hole in most of the phpnuke versions, then what i can do - try to
contact with all of the derivations authors? Its impossible...
So in case of phpnuke i will just release public advisory to
securityfocus, secunia and other lists and patches will be coming out
soon, thats sure. Of course, many sites will get hurt because of the
phpnuke insecurity (before they will be patched), but thats the life.
Postnuke authors are far more concerned about security and
they can be contacted before public advisory, so they can develope
patch before attacks go wild. Look here :

Developer is Francesco Burzi, not Francisco ;->
I always like your work. You should do some workshops as well.
The rest of the world should learn from you.
Cheers |

No, i suggest to try to contact with phpnuke team, of course.
What i am saing, is that i personally have bad experience with phpnuke security bugs reporting to developers. Its my personal experience and
to you i suggest to try to report security probs as by good traditions. |
