TITLE:
Easy File Sharing Web Server Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA28007

VERIFY ADVISORY:
http://secunia.com/advisories/28007/

CRITICAL:
Moderately critical

IMPACT:
Exposure of sensitive information, System access

WHERE:
>From remote

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

DESCRIPTION:
Luigi Auriemma has reported some vulnerabilities in Easy File Sharing
Web Server, which can be exploited by malicious people to disclose
sensitive information and by malicious users to compromise a
vulnerable system.

1) Input passed to unspecified parameters is not properly sanitised
when uploading files. This can be exploited to upload files to
arbitrary parent directories via directory traversal attacks.

2) An error exists when processing file download requests. This can
be exploited to download any ".sdb" database file except "admin.sdb"
or "user.sdb".

3) An error exists when processing username registration requests.
This can be exploited to disclose the contents of arbitrary files in
the users folder by creating an account with the username equal to
the name of the file.

The vulnerabilities are reported in version 4.5. Other versions may
also be affected.

SOLUTION:
Restrict access to trusted users only. The vendor will reportedly fix
the vulnerabilities in a future version.
