Description


Omni has discovered some vulnerabilities in FTP Admin, which can be exploited by malicious users to compromise a vulnerable system, and by malicious people to conduct cross-site scripting attacks and bypass certain security restrictions.

1) Input passed to the "page" parameter in index.php is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources or external FTP resources.

Successful exploitation of this vulnerability requires valid user credentials (but see #2).

2) A vulnerability is caused due to improper authentication verification in index.php. This can be exploited to log in and e.g. add new FTP users without having valid user credentials, by setting the "loggedin" parameter to "true".

Successful exploitation of this vulnerability requires that "register_globals" is enabled.

3) Input passed to the "error" parameter in index.php (when "page" is set to "error") 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 0.1.0. Other versions may also be affected.


Solution:
Restrict access to FTP Admin (e.g. with ".htaccess").
