使用IP构建URL是空白的

Question

I'm using CakePHP 3.5.17 and I'm trying to pass a URL with an IP from one of my forms and it's always being removed when I get to the controller.

If I post http://10.3.37 I receive

Array
(
    [asset_field_id] => 3
    [value] => http://10.3.37
    [asset_id] => 13
)

as expected. But if I put in the full address http://10.3.37.1 I receive

Array
(
)

If I change the IP to a domain name, or remove the 'h' or modify the string in any other way I get the result I'd expect. Is there some setting or security thing I'm not aware of?

Somewhere along the line all of the form data is being stripped out and I don't know where.

This form isn't using any kind of validation that I'm aware of.

Answer 1

I finally figured out the problem was ModSecurity. I loosened that up and thing started working as expected.
