Fusen News 3.3 Account Add Vulnerability

Author: DarkKnight
My site: http://www.insecureonline.com
Product: Fusen News 3.3 (maybe lower)
Side Note: This vulnerability is for an OLD VERSION of Fusen News. The 
only reason I'm posting this is because I still see people using Fusen 
News 3.3.
Vendors: Not contacted (Upgrade available with fix)

A vulnerability exists in Fusen News 3.3 that allows attackers to add 
accounts with admin or normal privlidges. If an account is added, the 
attacker will be able to modify news, post news, delete/add accounts, 
etc. When adding accounts, Fusen News 3.3 does not perform a login check, 
allowing anyone to add accounts through a direct URL.

A sample is listed below

id=signup&username=DarkKnight&email=EMAIL () EMAIL COM+&password=123456&icon=

The above URL would add the account "DarkKnight" with the 
password "123456" and the email "EMAIL () EMAIL COM" with Administrator 
abilities to the account list.

The vendor has already made upgrades for Fusen News 3.3 so to fix the 
vulnerability just upgrade. Besides, Fusen News 3.6 looks hot.

The two people who deserve credit for this vulnerability are: Fusen and 
DarkKnight [me :)]
