CVE-2008-5028 really speaks about 3.0.5 as about vulnerable to CSRF. At least CHANGE_ commands were closed in 3.0.5 and were (presumably) additionally closed at the Nagios server side in 3.0.6. So either 3.0.6 is vulnerable too, 3.0.5 is not vulnerable to CSRF or I am missing something. What to choose? Thanks! -- Eygene
