DESCRIPTION:
Some vulnerabilities have been reported in GroupLink eHelpDesk, which
can be exploited by malicious users to conduct script insertion
attacks and by malicious people to conduct cross-site scripting
attacks.

1) Input passed to the "NA_DISPLAYNAME" parameter in
helpdesk/user/rf_create.jsp is not properly sanitised before being
stored. This can be exploited to insert arbitrary HTML and script
code, which will be executed in an administrative user's browser
session in context of an affected site when the malicious data is
viewed.

2) Input passed to the "username" and "LDAPError" parameters in
index2.jsp 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 version 6.2.2. Other versions may
also be affected.

SOLUTION:
Filter malicious characters and character sequences in a web proxy.
