We have a critical vulnerability being reported at a website handled by us. The bug states that the "The application deserializes serial objects in an insecure manner" when a GET request along with a cookie named "WASPostParam" is sent to the server. After receiving the request from our server creates a TCP connection and waits in "FIN_WAIT" state, but there is no response from the server side and after the timeout of TCP connection the Postman application states that "Could not get a response from the server". We are using Postman application for sending the request. I have attached the cookie file, our httpd.conf and screenshots stating our vulnerability.
Kindly see the attachment for the files related to the problem and suggest the possible solution.


Thanks & Regards

If there's a problem deserializing this cookie, it's not in httpd.  httpd doesn't do anything but forward the [serialized] value to the application server.
