TITLE:
CF_Nuke Directory Traversal and Cross-Site Scripting Vulnerabilities

SECUNIA ADVISORY ID:
SA17939

VERIFY ADVISORY:
http://secunia.com/advisories/17939/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Exposure of sensitive information

WHERE:
>From remote

SOFTWARE:
CF_Nuke 4.x
http://secunia.com/product/6393/

DESCRIPTION:
r0t has discovered two vulnerabilities in CF_Nuke, which can be
exploited by malicious people to conduct cross-site scripting attacks
and to disclose potentially sensitive information.

1) Input passed to the "sector" and "page" parameters in "index.cfm"
isn't properly sanitised before being used to include ".cfm" files.
This can be exploited to include arbitrary ".cfm" files that are
accessible on the server.

Successful exploitation requires that "Sandbox Security" is not
enabled for the directory.

2) Input passed to the "cat", "topic", and "newsid" parameters isn't
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.

Successful exploitation requires that "Global Script Protection" is
disabled.

The vulnerabilities have been confirmed in version 4.6. Other
versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.

PROVIDED AND/OR DISCOVERED BY:
