DESCRIPTION:
Multiple vulnerabilities have been reported in Bradford Network
Sentry, which can be exploited by malicious users to conduct script
insertion attacks and by malicious people to conduct cross-site
request forgery attacks and bypass certain security restrictions.

1) Certain input passed to GuestAccess.jsp is not properly sanitised
before being displayed to the user. This can be exploited to insert
arbitrary HTML and script code, which will be executed in a user's
browser session when the malicious data is viewed.

2) 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 perform certain actions
with administrative privileges if a logged-in administrator visits a
malicious web site.

3) An error within the Bradford agent does not check for
authentication when processing certain actions, which can be
exploited to display arbitrary messages on a user's screen via a
specially crafted request sent to UDP port 4567.

The vulnerabilities are reported in version 5.3 NS500. Other versions
may also be affected.

SOLUTION:
Update to version 5.3.3.
