SECUNIA ADVISORY ID:
SA16630

VERIFY ADVISORY:
http://secunia.com/advisories/16630/

CRITICAL:
Less critical

IMPACT:
Security Bypass, Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
DownFile 1.x
http://secunia.com/product/5643/

DESCRIPTION:
benozor77 has discovered some vulnerabilities and a security issue in
DownFile, which can be exploited by malicious people to bypass certain
security restrictions and conduct cross-site scripting attacks.

1) Input passed to the "id" parameter in email.php, index.php,
del.php, and add_form.php is not properly sanitised before being
returned to users. This can be exploited to execute arbitrary HTML
and script code in a user's browser session in context of an affected
site.

2) It is possible to access the administration section without being
authenticated.

The vulnerabilities and security issue have been confirmed in version
1.3. Other versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised and
that users are properly authenticated.
