CVE-2025-0505
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedOn Arista CloudVision systems (virtual or physical on-premise deployments), Zero Touch Provisioning can be used to gain admin privileges on the CloudVision system, with more permissions than necessary, which can be used to query or manipulate system state for devices under management. Note that CloudVision as-a-Service is not affected.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA privilege escalation vulnerability in Arista CloudVision on-premise deployments allows Zero Touch Provisioning to be exploited to gain admin-level privileges with excessive permissions. This enables attackers to query and manipulate the state of devices managed by the CloudVision system.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify CloudVision deployment typeDetermine if you are running Arista CloudVision on-premise (CVP) rather than CloudVision as-a-Service (CVaaS). Check your deployment documentation, licensing model, or access the CloudVision interface URL - on-premise typically uses a local hostname/IP while CVaaS uses cloudvision.arista.comAffected if Deployment is CloudVision on-premise (not CVaaS)
-
Locate CloudVision versionAccess the CloudVision GUI or CLI and navigate to the About/System Information page to find the installed CloudVision version numberAffected if Version cannot be determined or is older than current release
-
Check ZTP service statusIn CloudVision, go to Inventory > ZTP section or use the CLI command 'ztp show' to determine if Zero Touch Provisioning is currently enabledAffected if ZTP is enabled on the CloudVision on-premise deployment
-
Verify ZTP network exposureReview network access controls and firewall rules around the CloudVision ZTP service ports (TCP 443, UDP 67/68). Check if ZTP interfaces are accessible from untrusted networks or the internetAffected if ZTP interfaces are accessible from untrusted or external networks
You are likely affected if you run CloudVision on-premise with ZTP enabled, regardless of version, since the vulnerability exists in the ZTP component itself.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataRestrict or disable ZTP access on affected CloudVision deployments, review ZTP configuration for security controls, and apply vendor-provided patches when available.
