Name of the Vulnerable Software and Affected Versions Efficient Networks 5861 DSL router version 5.3.80

Description The issue allows remote attackers to cause a denial of service, resulting in a crash, by flooding the WAN interface with TCP SYN packets using a tool like nmap, even when the firmware is configured to block incoming TCP SYN packets.

Recommendations For version 5.3.80, consider restricting access to the WAN interface or implementing rate limiting on TCP SYN packets as a temporary mitigation measure to minimize the risk of a denial of service. At the moment, there is no information about a newer version that contains a fix for this issue.
