Description:  
PhotoPost was designed to help you give your users exactly   
what they want. Your users will be thrilled to finally be   
able to upload and display their photos for your entire   
community to view and discuss, all with no more effort than   
it takes to post a text message to a forum. If you already   
have a forum (vBulletin, UBB Threads, phpBB, DCForum, or   
InvisionBoard), you'll appreciate that PhotoPost was designed   
to seamlessly integrate into your site without the need for   
your users to register twice and maintain two logins. Where you   
see [INT] in this advisory, it represents an integer such as a   
valid category. [XSS] and [SQL] represent where an attacker could   
insert code to conduct a cross site scripting attack, or inject   
data to influence SQL queries.  
  
  
  
Cross Site Scripting:  
PhotoPost is prone to cross site scripting in several different   
scripts throughout the application. Below are examples:  
  
  
http://path/showgallery.php?cat=[INT]&page=[XSS]  
http://path/showgallery.php?si=[XSS]  
http://path/showgallery.php?cat=[INT][XSS]  
http://path/showgallery.php?ppuser=[INT]&cat=[INT][XSS]  
  
This can be used to render hostile code in the context of the   
victims browser, or to steal cookie based credentials or other  
sensitive info.  
  
  
  
SQL Injection Vulnerabilities:  
There are a substantial number of SQL Injection vulnerabilities in   
this application. Some are easy to exploit, others are not so easy.  
  
http://path/showgallery.php?cat=[INT][SQL]  
http://path/showgallery.php?ppuser=[INT][SQL]&cat=[INT]  
  
These SQL issues can possibly be exploited to influence SQL queries   
and disclose arbitrary data. These will alse cause XSS if unsuccessful.  
  
  
  
Proof Of Concept:  
Due to the fact that some people feel the issues in this advisory and   
our last PhotoPost advisory were not accurate and unexploitable we have   
decided to include a proof of concept.  
  
http://path/showgallery.php?ppuser=-2'%20UNION%20SELECT%200,email,  
0,0,0,0,0,0%20FROM%20user%20WHERE%20userid='1&cat=500  
  
The above example is relatively harmless, but will pull the private   
email address of a user. This could just as easily be an admin password   
hash. This works on all versions prior to recently released PhotoPost 4.86  
  
  
  
Solution:  
PhotoPost 4.86 has been released to address these issues. Users should  
upgrade their installation as soon as possible.
