SECUNIA ADVISORY ID:

VERIFY ADVISORY:
http://secunia.com/advisories/23625/

CRITICAL:
Less critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
Fix And Chips CMS System 1.x
http://secunia.com/product/13177/

DESCRIPTION:
Luny has discovered several vulnerabilities in Fix And Chips CMS
System, which can be exploited by malicious users to conduct script
insertion attacks and by malicious people to conduct cross-site
scripting attacks.

1) Input passed to the "id" parameter in delete-announce.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.

2) Input passed to the form field "Announcement" in staff.php and the
form fields "Client Name", "Business Name", "Street", "Address 2",
"Town/City", "Postcode", "Phone Number", "Email Address" and "Website
Address" in new_customer.php is not properly sanitised before being
stored. This can be exploited to insert arbitrary HTML and script
code, which is executed in a user's browser session in context of an
affected site when the offending data is viewed.

Successful exploitation of this vulnerability requires valid user
credentials.

The vulnerabilities are confirmed in version 1.0. Other versions may
also be affected.

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