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

http://www.website.com/FusenNews/?

id=signup&username=DarkKnight&email=EMAIL (at) EMAIL (dot) COM+ [email concealed]&password=123456&ico
n=

&le=3

The above URL would add the account "DarkKnight" with the

password "123456" and the email "EMAIL (at) EMAIL (dot) COM [email concealed]" 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 :)]
