DESCRIPTION:
High-Tech Bridge SA has discovered some vulnerabilities in DT
Centrepiece, which can be exploited by malicious users to perform
certain actions with escalated privileges and malicious people to
conduct cross-site scripting attacks and bypass certain security
restrictions.

1) Input passed via the "searchFor" parameter to search.asp 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.

2) Input passed via the "c" parameter to login.asp 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.

3) Input passed via the "user" parameter to register.asp 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.

4) An error in the application uses predictable values to validate a
user registration and can be exploited to register and validate
arbitrary users.

Successful exploitation of this vulnerability requires that "Register
Mode" is set to "UserEmail".

5) An error in the application allows access to other user accounts
by checking if the "_Remember_Username" cookie is a username of a
valid user and can be exploited to e.g. gain privileges of another
user.

The vulnerabilities are confirmed in version 4.5. Other versions may
also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised and
verified.
