CVE-2025-0505 in CloudVision Portal
Summary
by MITRE • 05/08/2025
On 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.

This vulnerability exists within Arista CloudVision systems where the Zero Touch Provisioning feature can be exploited to escalate privileges and gain administrative access. The flaw allows an attacker to obtain administrative privileges with excessive permissions that exceed what is required for normal operation, creating a significant security risk for on-premise deployments. The vulnerability specifically affects virtual or physical CloudVision systems that are deployed on-premise, while CloudVision as-a-Service offerings remain unaffected by this particular issue. The technical implementation appears to involve improper privilege validation or access control mechanisms within the Zero Touch Provisioning workflow that permits privilege escalation beyond intended boundaries.
The operational impact of this vulnerability is substantial as it enables unauthorized users to gain administrative control over CloudVision systems that manage network devices. This elevated privilege level allows attackers to query and manipulate the system state of all devices under management, potentially leading to complete network compromise. The excessive permissions granted through this vulnerability mean that attackers can perform actions that should be restricted to authorized administrators only, including but not limited to device configuration changes, monitoring activities, and data access. This represents a critical privilege escalation vulnerability that can be exploited to undermine the security posture of the entire network infrastructure managed by CloudVision.
From a cybersecurity perspective, this vulnerability aligns with CWE-269 which addresses improper privilege management and CWE-798 which covers the use of hard-coded credentials or excessive privileges. The attack pattern follows principles outlined in ATT&CK technique T1068 which involves exploiting legitimate credentials to gain system access. The vulnerability represents a significant concern for organizations relying on CloudVision for network management, as it provides a path for attackers to bypass normal access controls and gain unauthorized administrative access. The fact that this affects on-premise deployments specifically indicates that organizations with cloud-based CloudVision services are not vulnerable, though they should still maintain proper security hygiene.
Organizations should implement immediate mitigations including restricting network access to CloudVision systems, implementing strict access controls for Zero Touch Provisioning functionality, and monitoring for unauthorized administrative activities. Security teams should also review and validate all current access controls and privilege assignments to ensure that no excessive permissions have been granted. The recommended approach includes disabling or heavily restricting Zero Touch Provisioning when not actively needed, implementing network segmentation to limit access to CloudVision systems, and conducting thorough audits of administrative access logs to detect any suspicious activities. Additionally, organizations should ensure that all CloudVision systems are kept up-to-date with the latest security patches and updates provided by Arista to address this vulnerability and similar issues that may arise in the future.
