TITLE:
cPanel Multiple Cross-Site Scripting Vulnerabilities

SECUNIA ADVISORY ID:
SA21592

VERIFY ADVISORY:
http://secunia.com/advisories/21592/

CRITICAL:
Less critical

IMPACT:
Cross Site Scripting

WHERE:
From remote

SOFTWARE:
cPanel 10.x
http://secunia.com/product/5280/

DESCRIPTION:
Preth00nker has reported some vulnerabilities in cPanel, which can be
exploited by malicious people to conduct cross-site scripting
attacks.

Input passed to the "dir" parameter in dohtaccess.html and to the
"file" parameter in editit.html and showfile.html is not 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.

Examples:
http://[host]:2082/frontend/x/htaccess/dohtaccess.html?dir=[code]
http://[host]:2082/frontend/x/files/editit.html?dir=/&file=[code]
http://[host]:2082/frontend/x/files/showfile.html?dir=/&file=[code]

SOLUTION:
Filter malicious characters and character sequences in a web proxy.

PROVIDED AND/OR DISCOVERED BY:
Preth00nker
