Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.17%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Internet Initiative Japan Inc. SEIL Series routers SEIL/X1 2.50 through 4.62, SEIL/X2 2.50 through 4.62, SEIL/B1 2.50 through 4.62, and SEIL/x86 Fuji 1.70 through 3.22 allow remote attackers to cause a denial of service (CPU and traffic consumption) via a large number of NTP requests within a short time, which causes unnecessary NTP responses to be sent.
