CVE-2021-46082
Moxa TN-5900 v3.1 series routers, MGate 5109 v2.2 series protocol gateways, and MGate 5101-PBM-MN v2.1 series protocol gateways were discovered to contain a memory leak which allows attackers to cause a Denial of Service (DoS) via crafted packets.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.18%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
