AdMentor Login Flaw
From: Frank <thran60 () hotmail com>

Regarding : AdMentor v2.11 and earlier
Homepage: http://www.aspcode.net

AdMentor allows any user to login as admin.

The base path of the login is usually :


By using Login : ' or ''='   , and Password : ' or ''='
We create a legal query because it will get appended 
as :SELECT row FROM table WHERE login = '' or 

Same goes for the password. This allows us to login 
without any trouble as the main admin. Vendor has 
been warned of the bug, but has not released a patch 
yet. Temporary solution, filter out the bad chars ' " ~ \ 
/ by using the following piece of javascript :

function RemoveBad(strTemp) { 
    strTemp = strTemp.replace(/\<|\>|\"|\'|\%|\;|\(|\)|\&|\+|
    return strTemp; }

And calling it from within the asp script :

var login = var TempStr = RemoveBad

var password = var TempStr = RemoveBad

Iam not sure about the correct vars set in the form, 
you might want to tweak it just a bit. Havent drunk my 
coffee yet :)
