Details

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)
