CVE-2017-12736
This could allow an attacker located in the adjacent network of the targeted device to perform unauthorized administrative actions.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.07%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
After initial configuration, the Ruggedcom Discovery Protocol (RCDP) is still able to write to the device under certain conditions. This could allow an attacker located in the adjacent network of the targeted device to perform unauthorized administrative actions.
