Source: CVE
Vendor/Project: Arista Networks
Product: CloudVision Portal

Description

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.

Technical Analysis

CVE-2025-0505 is a critical vulnerability affecting Arista Networks CloudVision Portal versions 2024.2.0 and 2024.3.0, specifically in on-premise deployments (both virtual and physical). The vulnerability arises from improper privilege management (CWE-269) in the Zero Touch Provisioning (ZTP) feature. An attacker can exploit this flaw to gain administrative privileges on the CloudVision system without requiring authentication or user interaction. This elevated access grants the attacker permissions beyond what is necessary, enabling them to query or manipulate the system state of managed network devices. The vulnerability does not affect the CloudVision as-a-Service offering, limiting the scope to on-premise deployments. The CVSS v3.1 score is 10.0 (critical), reflecting the vulnerability's ease of exploitation (network vector, no privileges or user interaction required), and its severe impact on confidentiality and integrity, with a scope change indicating that the compromise of CloudVision can affect managed devices. Although no known exploits are currently reported in the wild, the critical nature and straightforward exploitation vector make this a high-risk issue for organizations using affected versions of CloudVision Portal on-premise.

Potential Impact

For European organizations, this vulnerability poses a significant risk to network infrastructure management. CloudVision Portal is widely used for centralized management and automation of network devices, including switches and routers. Exploitation could allow attackers to gain full administrative control over the CloudVision system, enabling unauthorized access to sensitive network configurations and potentially allowing manipulation or disruption of network devices under management. This could lead to data breaches, network outages, or persistent backdoors within critical infrastructure. Given the criticality of network infrastructure in sectors such as finance, telecommunications, government, and energy across Europe, the impact could be severe, including operational disruption and compromise of sensitive data. The vulnerability's ability to escalate privileges without authentication increases the risk of insider threats or external attackers leveraging initial access to escalate privileges rapidly. The lack of impact on CloudVision as-a-Service limits exposure to organizations using on-premise deployments, which are common in highly regulated or security-sensitive environments prevalent in Europe.

Mitigation Recommendations

Immediate mitigation should focus on upgrading affected CloudVision Portal instances to patched versions once available from Arista Networks, as no patch links are currently provided. Until patches are released, organizations should restrict network access to the CloudVision management interface, implementing strict network segmentation and firewall rules to limit exposure to trusted administrative hosts only. Employing multi-factor authentication (MFA) on all administrative access points, even if not directly mitigating this vulnerability, can reduce risk from lateral movement. Monitoring and logging of all ZTP-related activities and administrative actions on CloudVision should be enhanced to detect anomalous behavior indicative of exploitation attempts. Additionally, organizations should review and harden privilege assignments within CloudVision to minimize the impact of any unauthorized privilege escalation. Conducting a thorough audit of all managed devices and configurations post-incident is recommended to ensure no unauthorized changes occurred. Finally, organizations should engage with Arista support for guidance and subscribe to vulnerability advisories to receive timely updates.
