Introduction

============

moziloWiki is an easy to handle wiki system.



More Details

============

1. Directory Traversal:

----------------------

Affected files:

print.php -> page parameter



Acquiring access to known files outside of the web root and current directory

is possible through directory traversal techniques.

This is made possible through the use of "../../" in a HTTP request.



2. Cross Site Scripting:

----------------------

Affected files:

index.php -> action parameter

index.php -> page parameter



Affected parameters are not being properly sanitised before being returned to 
the user.

This can be exploited to execute arbitrary HTML and script code in a user's 
browser session in context of an affected site.



3. session fixation:

---------------------

The "PHPSESSID" parameter can be set to a malicious and arbitrary value.



3.1 Description:

In a session fixation attack, the attacker fixes the user's session ID before 
the user even logs into the target server.

After a user's session ID has been fixed, the attacker will wait for them to 
login.

Once the user does so, the attacker uses the predefined session ID value to 
assume their online identity.



3.2 PoC:

============

http://localhost/mozilowiki/?PHPSESSID=15031988
