NimbostratusAlert or Block GET requests with data
We have a webpage with a username field, we'd like to prevent malicious actions by ensuring a GET with data cannot be accomplished. I would be happy with an iRule that looked to see if there was data...
I may have misunderstood the question, but if you enable an ASM policy, it is one of the basic check it enforces, under HTTP Protocol Compliance ("Body in GET of HEAD requests") - you need to make sure it is checked in the Policy Blocking Settings configuration page, and that your policy is set to Blocking.
To drop:
when HTTP_REQUEST {
if { [HTTP::method] eq "GET" } {
HTTP::collect 10
}
}
when HTTP_REQUEST_DATA {
HTTP::release
reject
}
- You may also want to set the HTTP profile to UNCHUNK the requests. And look for the presence of the Content-Length header.
