DESCRIPTION:
Michael Messner has reported two vulnerabilities in Linksys WRT54GL,
which can be exploited by malicious people to conduct cross-site
scripting and cross-site request forgery attacks.
1) The application 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 password if a
logged-in administrator visits a malicious web site.
2) Input passed via the "submit_button" POST parameter to apply.cgi
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 reported in firmware version 4.30.15. Prior
versions may also be affected.
SOLUTION:
Update to firmware version 4.30.16.
