Advanced Electron Forums (AEF) 1.0.9 <= Cross Site Request Forgery
The Advanced Electron Forums (AEF) 1.0.9 <= versions are vulnerable
to Cross Site Request Forgery (CSRF).
AEF has a very simple and easy to use Administration Panel and
installing this software is a piece of cake! You can install new
themes, customize themes the way you want. The User Control Panel has
a simple yet beautiful interface where users can set their preferences
for the board.
3. VULNERABILITY DESCRIPTION
Advanced Electron Forums (AEF) 1.0.9 <= versions contain a flaw that
allows a remote Cross-site Request Forgery (CSRF / XSRF) attack. The
flaw exists because the application does not require multiple steps or
explicit confirmation for sensitive transactions for majority of
administrator functions such as adding new user, assigning user to
administrative privilege. By using a crafted URL, an attacker may
trick the victim into visiting to his web page to take advantage of
the trust relationship between the authenticated victim and the
application. Such an attack could trick the victim into executing
arbitrary commands in the context of their session with the
application, without further prompting or verification.
4. VERSIONS AFFECTED
The following request ecalates a normal user to an administrator.
POST /aef/index.php?act=editprofile&uid=2 HTTP/1.1
Partial fix is available.
