CVE-2021-30127
TerraMaster F2-210 devices through 2021-04-03 use UPnP to make the admin web server accessible over the Internet on TCP port 8181, which is arguably inconsistent with the "It is only available on the local network" documentation.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.88%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description

NOTE: manually editing /etc/upnp.json provides a partial but undocumented workaround.
