NAT Slipstreaming allows an attacker to remotely access any TCP/UDP services bound to a victim machine, bypassing the victim's NAT/firewall arbitrary firewall pinhole control. A remote attacker can exploit this vulnerability by enticing a user to visit a specially crafted web page...

Check Point Response to CVE-2020-28041 - NAT Slipstreaming

Cause The attack involves several vectors - Local IP disclosure, max MTU UDP and TCP calculation and leveraging a SIP parser weakness in fragmented HTTP packets which enables to "Slipstream" a legitimate SIP connection in an HTTP POST request generated by the victim's browser. The full descriptio...
