DESCRIPTION:
0a29406d9794e4f9b30b3c5d6702c708 has reported a security issue and
multiple vulnerabilities in Nagios XI, which can be exploited by
malicious, local users to perform certain actions with escalated
privileges and by malicious people to conduct cross-site scripting
attacks.

1) Input appended to the URL after e.g. login.php, index.php,
about/index.php, etc. is not properly sanitised in
html/includes/pageparts.inc.php and in the "get_permalink_base()"
function in html/includes/utils.inc.php 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 "xiwindow" parameter to account/ is not
properly sanitised in the "get_window_frame_url()" function in
html/includes/pageparts.inc.php 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 appended to the URL after
includes/components/xicore/recurringdowntime.php 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) Input passed via the "height", "service", and "width" parameters
to reports/alertheatmap.php 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.

5) Input passed via the "service" parameter to reports/histogram.php,
reports/statehistory.php, or reports/notifications.php is not properly
sanitised in the "get_service_status_detail_link()" function in
includes/utils-links.inc.php 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.

6) Input passed via the "host" and "service" parameters to
reports/notifications.php is not properly sanitised in the
"get_host_status_detail_link()" in includes/utils-links.inc.php
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.

7) The security issue is caused due to certain scripts using
temporary files in an insecure manner, which can be exploited to e.g.
overwrite arbitrary files via symlink attacks.

The vulnerabilities are reported in version 2011R1.8. Prior versions
may also be affected.

SOLUTION:
Update to version 2011R1.9.
