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
