CVE-2018-10713
An authenticated user can pass a long buffer as a 'read' parameter to the '/userfs/bin/tcapi' binary (in the Diagnostics component) using the 'read <node_name>' function and cause memory corruption.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.37%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
