A privileged attacker can exploit certain operation to execute arbitrary commands with root privileges, leading to full device compromise. An authenticated user can exploit gRPC Network Security Interface (gNSI) Certz service on Arista EOS-based products to escalate privileges and execute arbitrary OS commands via a crafted Certz Rotate request. The Bootz service is also affected.
