I keep getting error messages like these on a server running an installation of an embedded Mongoose webserver
[1280931978] [error] [client 66.65.74.105] CCM_POST /ccm_system/request: Error 400: Bad Request
[1280931558] [error] [client 71.162.141.214] CCM_POST /ccm_system/request: Error 400: Bad Request
I figured out that CCM_POST seems to be some kind of HTTP command LIKE GET, POST, PUT and DELETE, but what is it supposed to do?
Is that some kind of vulnerability scan?
A rather confused Microsoft System Center Configuration Manager Client is trying to connect to it's site server, which it thinks your web server is.
