"It was discovered that Nagios was vulnerable to a Cross-site request
forgery (CSRF) vulnerability. If an authenticated nagios user were
tricked into clicking a link on a specially crafted web page, an
attacker could trigger commands to be processed by Nagios and execute
arbitrary programs. This update alters Nagios behaviour by disabling
submission of CMD_CHANGE commands. (CVE-2008-5028)

It was discovered that Nagios did not properly parse commands
submitted using the web interface. An authenticated user could use a
custom form or a browser addon to bypass security restrictions and
submit unauthorized commands. (CVE-2008-5027).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
