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.cook ie%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=adm in
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%2 8document.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=authsyst em&tabmodule=%3Cscript%3Ealert%28document.cookie%29;%3C/script%3E&type=admin |
