Name of the Vulnerable Software and Affected Versions NETGEAR Nighthawk R7000 version 1.0.9.64 10.2.64

Description The issue 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. This is due to the SIP ALG implementation taking action based on an IP packet with an initial REGISTER substring in the TCP data and the correct intranet IP address in the subsequent Via header, without properly considering connection progress and fragmentation.

Recommendations For NETGEAR Nighthawk R7000 version 1.0.9.64 10.2.64, consider disabling the SIP ALG feature as a temporary workaround until a patch is available. Restrict access to the SIP ALG module to minimize the risk of exploitation. Avoid using the REGISTER substring in the TCP data and the Via header in the affected API endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
