http://secunia.com/advisories/22602/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Exposure of sensitive information

WHERE:
>From remote

SOFTWARE:
Easy File Sharing Web Server 4.x
http://secunia.com/product/12461/

DESCRIPTION:
Greg Linares has discovered some vulnerabilities in Easy File Sharing
Web Server, which can be exploited by malicious users to conduct
script insertion attacks and by malicious people to disclose
sensitive information.

1) Input passed to the "author", "content", and "title" parameters
when posting a new forum thread is not properly sanitised before
being used. This can be exploited to execute arbitrary HTML and
script code in a user's browser session when malicious data is
viewed.

2) An error exists within the handling of alternative data streams.
When running on a NTFS file system, this can be exploited to disclose
the content of arbitrary files in the web root by appending "::$DATA"
to the request. This allows to gain knowledge of user and
administrator login credentials, cryptographic keys and certificates,
private messages, logfiles, and other sensitive information.

The vulnerabilities are confirmed in version 4.0. Other versions may
also be affected.

SOLUTION:
Greg Linares

PROVIDED AND/OR DISCOVERED BY:
Grant access to trusted users only. Use in trusted network
environments only.
