UBB.threads PHP Forum Software Community Forums General Off Topic well this sucks..

I just found an easy way to check whether ModSecurity is present. Just add cmd.exe somewhere in the URL.

For example: DOMAIN/forums/ubbthreads.php/cmd.exe

This will trigger one of the more ridiculous ModSecurity rules and should return 403 Forbidden on server with enabled ModSecurity. Servers without ModSecurity will ignore this.
