Advisory Details:

High-Tech Bridge Security Research Lab discovered four XSS vulnerabilities in 
Xaraya, which can be exploited to perform cross-site scripting attacks against 
administrators of vulnerable application.


1) Multiple Cross-Site Scripting (XSS) in Xaraya: CVE-2013-3639

1.1 The vulnerability exists due to insufficient sanitisation of user-supplied 
data passed via the "id" HTTP GET parameter to "/index.php" script. A remote 
attacker can trick a logged-in administrator to open a specially crafted link 
and execute arbitrary HTML and script code in browser in context of the 
vulnerable website.

The exploitation example below uses the "alert()" JavaScript function to 
display administrator's cookies:

http://xaraya/index.php?func=modinfonew&id=%3Cscript%3Ealert%28document.cookie%29;%3C/script%3E&module=modules&type=admin


1.2 The vulnerability exists due to insufficient filtration of user-supplied 
data passed via the "interface" HTTP GET parameter to "/index.php" script. A 
remote attacker can trick a logged-in administrator to open a specially crafted 
link and execute arbitrary HTML and script code in browser in context of the 
vulnerable website.

The exploitation example below uses the "alert()" JavaScript function to 
display administrator's cookies:

http://xaraya/index.php?block_id=7&func=modify_instance&interface=%3Cscript%3Ealert%28document.cookie%29;%3C/script%3E&module=blocks&tab=config&type=admin


1.3 The vulnerability exists due to insufficient sanitisation of user-supplied 
data passed via the "name" HTTP GET parameter to "/index.php" script. A remote 
attacker can trick a logged-in administrator to open a specially crafted link 
and execute arbitrary HTML and script code in browser in context of the 
vulnerable website.

The exploitation example below uses the "alert()" JavaScript function to 
display administrator's cookies:

http://xaraya/index.php?func=aliases&module=modules&name=%3Cscript%3Ealert%28document.cookie%29;%3C/script%3E&type=admin


1.4 The vulnerability exists due to insufficient filtration of user-supplied 
data passed via the "tabmodule" HTTP GET parameter to "/index.php" script. A 
remote attacker can trick a logged-in administrator to open a specially crafted 
link and execute arbitrary HTML and script code in browser in context of the 
vulnerable website.

The exploitation example below uses the "alert()" JavaScript function to 
display administrator's cookies:

http://xaraya/index.php?func=assignprivileges&module=privileges&tab=authsystem&tabmodule=%3Cscript%3Ealert%28document.cookie%29;%3C/script%3E&type=admin
