TITLE:
SyndeoCMS File Disclosure and Cross-Site Scripting

SECUNIA ADVISORY ID:
SA30602

VERIFY ADVISORY:
http://secunia.com/advisories/30602/

CRITICAL:
Less critical

IMPACT:
Cross Site Scripting, Exposure of system information, Exposure of
sensitive information

WHERE:
>From remote

SOFTWARE:
SyndeoCMS 2.x
http://secunia.com/product/16441/

DESCRIPTION:
CWH Underground has discovered some vulnerabilities in SyndeoCMS,
which can be exploited by malicious people to conduct cross-site
scripting attacks, and by malicious users to disclose sensitive
information.

1) Input passed to the "template" parameter in
starnet/editors/fckeditor/studenteditor.php is not properly sanitised
before being used. This can be exploited to display arbitrary files
via directory traversal attacks.

Successful exploitation of this vulnerability requires valid pupil
user credentials.

2) Input passed to the "template" parameter in starnet/index.php is
not properly sanitised before being used. This can be exploited to
display arbitrary files via directory traversal attacks.

Successful exploitation of this vulnerability requires valid
administrator credentials.

3) Input passed to the "section" parameter in index.php 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.

The vulnerabilities are confirmed in version 2.6.01. Other versions
may also be affected.

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