[Bug 1717121] [NEW] Security group Inbound rule allows ip addresses with /0 option.

 

Public bug reported:

Under security groups, when we try to add a new inbound rule using CIDR
it doesn`t validate the input.

example.

0.0.0.0/0 is a rule that will open inbound access to internet. but at
the same time if there is a valid ip e.g. 172.155.0.0/0 then "0" bit
match should not be allowed.


This UI validation is the part of AWS. so even if someone by mistake types the /0 with valid ip address it will make the rule to open the inbound to entire internet.
