DESCRIPTION:
Two vulnerabilities have been reported in the ZTE ZXDSL 831 II modem,
which can be exploited by malicious people to conduct cross-site
request forgery attacks and to disclose sensitive information.

1) The application's web interface allows users to perform certain
actions via HTTP requests without performing any validity checks to
verify the requests. This can be exploited to e.g. change an
administrator's password by tricking a logged in administrator into
visiting a malicious web site.

2) The vulnerability is caused due to the application displaying
authentication credentials in the accessaccount.cgi script, which can
be exploited to disclose the authentication credentials.

The vulnerabilities are reported in version 7.5.0a_Z29_OV. Other
versions may also be affected.

SOLUTION:
Restrict access to trusted users only. Do not browse untrusted
websites or follow untrusted links while logged in to the
application.

PROVIDED AND/OR DISCOVERED BY:
Mehdi Boukazoula and Ibrahim Debeche.
