Zikula CMS 1.2.4 <= Cross Site Request Forgery (CSRF) Vulnerability (CVE-2011-0535)

By YGN Ethical Hacker Group -

1. OVERVIEW

The Zikula 1.2.4 and lower versions were vulnerable to Cross Site Request Forgery (CSRF).


2. BACKGROUND

Zikula is a Web Application Toolkit, which allows you to run impressive websites and build powerful online applications. Zikula has received praise for many things, but we belive the highlights are ease of use, quick and easy development, security and performance and lastly flexibility.


3. VULNERABILITY DESCRIPTION

Zikula CMS 1.2.4 and lower 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

1.2.4 <=


5. PROOF-OF-CONCEPT/EXPLOIT

The following request escalates a normal user to an administrator.

[REQUEST]
POST /zikula/index.php?module=users&type=admin&func=processusers&op=edit HTTP/1.1
