PHP-Nuke x.x AND PostNuke x.x SQL Injection

[pedro.inacio () netropolis pt (Pedro Inacio)]

Hello again,

just to say that PostNuke ( fork of PHP-Nuke ) is vulnerable to the same
bugs
AND
it is possible to inject different SQL code in order to do other "funny" but
"dangerous" things.

Note to the guys of those projects:
Filter those URL entries!!!

Cheers,

Pedro Inacio
