Vendor Workaround
For the Bootz service: - Do not include X509 PEM certificates in the initial CertzProfile during Bootz provisioning. For the Certz service (choose one): Option 1: Disable gNSI Certz entirely (requires manual SSL profile management going forward): switch(config)#management api gnsi switch(config-mgmt-api-gnsi)#no service certz Option 2: Restrict Certz access using a gNSI Authz policy. Apply an authorization policy that limits the Certz Rotate RPC to only explicitly permitted users: switch(config)#management api gnsi switch(config-mgmt-api-gnsi)#service authz To detect potential exploitation, configure auditd to monitor for suspicious child processes spawned by OpenConfig/Octa services: switch(config)#monitor security audit switch(config-audit)#rule group process-creation -a always,exit -F arch=b64 -S execve -k process-create -a always,exit -F arch=b32 -S execve -k process-create EOF switch(config-audit)#monitor group process-creation

| Description | 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. | |
