Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (2.21%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

An issue was discovered in Siklu Communications Etherhaul 8010TX and 1200FX devices, Firmware 7.4.0 through 10.7.3 and possibly other previous versions. The rfpiped service listening on TCP port 555 which uses static AES encryption keys hardcoded in the binary. These keys are identical across all devices, allowing attackers to craft encrypted packets that execute arbitrary commands without authentication. This is a failed patch for CVE-2017-7318. This issue may affect other Etherhaul series devices with shared firmware.
