Remote Attackers Can Now Reach Protected Network Devices via NAT Slipstreaming

Disconnecting devices from the internet is no longer a solid plan for protecting them from remote attackers. A new version of a known network-address translation NAT slipstreaming attack has been uncovered, which would allow remote attackers to reach multiple internal network devices, even if tho...

New Attack Could Let Remote Hackers Target Devices On Internal Networks

A newly devised variant of the NAT Slipstreaming attack can be leveraged to compromise and expose any device in an internal network, according to the latest research. Detailed by enterprise IoT security firm Armis, the new attack CVE-2020-16043 and CVE-2021-23961 builds on the previously disclose...

NAT Slipstream Bypass Attempt

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...

CVE-2020-28041

The SIP ALG implementation on NETGEAR Nighthawk R7000 1.0.9.6410.2.64 devices allows remote attackers to communicate with arbitrary TCP and UDP services on a victim's intranet machine, if the victim visits an attacker-controlled web site with a modern browser, aka NAT Slipstreaming. This occurs...
