[HTTP::uri] contains "*"

 A vulnerability has been detected in the application, and if someone puts the character "*" in the url, it goes where it doesn't have to.

we thought about doing a simple redirect, but it doesn't work.

when HTTP_REQUEST {

if { [HTTP::uri] equals "/" || [HTTP::uri] equals "/example1" || [HTTP::uri] contains "*" }

{

   HTTP::redirect "https://[HTTP::host]/blabla/"

}

}

the original irule did not have [HTTP :: uri] contains "*". has been put it and failed.

any ideas please?

thanks in advance
