Overview<\/strong><\/p>\n

The CVE-2025-0505 vulnerability is a critical security flaw found in Arista CloudVision systems, both virtual and physical on-premise deployments. This vulnerability is significant as it allows attackers to exploit Zero Touch Provisioning to gain admin privileges on the CloudVision system. This results in them having more permissions than necessary, which can then be used to query or manipulate system state for devices under management<\/a>. It is worth mentioning that CloudVision as-a-service deployments are not affected by this vulnerability<\/a>.
\nThe severity of this vulnerability underscores the importance of swift action and remediation by system administrators managing Arista CloudVision<\/a> systems. The potential for system<\/a> compromise and data leakage is high, posing a significant risk to organizations that have deployed these systems.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-0505
\nSeverity: Critical, CVSS score of 10.0
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise<\/a>, data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Arista CloudVision (Physical Deployments) | All versions prior<\/a> to the vendor patch
\nArista CloudVision (Virtual Deployments) | All versions prior<\/a> to the vendor patch<\/p>\n

How the Exploit Works<\/strong><\/p>\n

This exploit takes advantage of a flaw in the Zero Touch Provisioning feature of Arista<\/a> CloudVision systems. An attacker, without needing any specific user privileges or interactions, can send specially crafted network requests to the system<\/a>. These requests can trick the system into granting the attacker admin-level privileges<\/a>. Once this level of access is gained, the attacker can query or manipulate system state for devices under management, potentially leading to system<\/a> compromise and data leakage.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here’s a
\nconceptual<\/strong>
\n example of how this vulnerability could be exploited:<\/p>\n

POST \/zerotouch\/provisioning HTTP\/1.1\nHost: cloudvision.example.com\nContent-Type: application\/json\n{\n\"request_type\": \"provision\",\n\"credentials\": {\n\"admin_privileges\": \"true\"\n}\n}<\/code><\/pre>\n
In the above example, a malicious actor sends a POST request to the Zero Touch Provisioning endpoint, requesting provisioning with admin privileges<\/a>. If the system is vulnerable<\/a>, it would grant these privileges, allowing the attacker broad access to system features and data.<\/p>\n","protected":false},"excerpt":{"rendered":"
