DESCRIPTION:
A weakness and a vulnerability have been reported in DotNetNuke. The
weakness may lead to exposure of sensitive information and the
vulnerability can be exploited by malicious users to conduct script
insertion attacks.

1) The weakness is caused due to the install wizard displaying SQL
exception messages if a connection to the database fails. This can
lead to the exposure of certain sensitive information e.g. database
name or the user name.

The weakness is reported in versions prior to 5.4.1

2) Input passed via the user messaging module 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 when the malicious
message is being viewed.

The vulnerability is reported in versions 5.3.0 through 5.4.1.

SOLUTION:
Update to version 5.4.2 or later.

PROVIDED AND/OR DISCOVERED BY:
1) The vendor credits the PowerDNN Engineering Team
2) The vendor credits Chris Wood
