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

1) Input passed via the URL is not properly sanitised before being
used to construct reports from filtered web content. This can be
exploited to insert arbitrary HTML and script code, which will be
executed in a user's browser session in context of an affected site
when the malicious data is viewed.

2) Input passed via the "Full Name" field to Administrators of the
Administrators section, via the Name and Description fields to
Categories of the "Filtering & Protection" section, via the Name
field to Identify of the Identification section, via the Username
field to Users of the "Users & Groups" section, via the Name and
Description fields to Groups of the "Users & Groups" section, via
Name and Description fields to "Filtering Policies", via the
"Original URL" and Redirection fields to "Proxy & Cache", via the
Destination field to Email of the Alerts section, via the Name field
to "Access Denied Page" of the "Appliance Customization" section, via
the Name field to "Login Page" of the "Appliance Customization"
section, via the Name field to "Logout Denied Page" of the "Appliance
Customization" section is not properly sanitised before being used.
This can be exploited to insert arbitrary HTML and script code, which
will be executed in a user's browser session in context of an affected
site if malicious data is viewed.

3) 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 cause unspecified impacts by
tricking a logged in administrator into visiting a malicious web
site.

4) Input passed via the URL when using HTTPS is not properly
sanitised before being returned to the user in a Microdasys SSL error
page. This can be exploited to execute arbitrary HTML and script code
in a user's browser session in context of an affected site.

Successful exploitation requires that the target server of the URL
does not support HTTPS.

5) An error due to the application not properly verifying the
X-Forwarded-For HTTP header can be exploited to bypass IP
restrictions and access blocked sites.

The vulnerabilities are reported in versions prior to 5.0.14.

SOLUTION:
Update to version 5.0.14.
