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.

Comprehensive Technical Analysis of EUVD-2025-14029
1. Vulnerability Assessment and Severity Evaluation
The vulnerability described in EUVD-2025-14029 affects Arista CloudVision systems, specifically the Zero Touch Provisioning (ZTP) feature. This vulnerability allows an attacker to gain administrative privileges on the CloudVision system, which can be exploited to query or manipulate the system state for devices under management. The CVSS (Common Vulnerability Scoring System) base score of 10.0 indicates a critical severity level. The scoring vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:N breaks down as follows:
- AV:N (Attack Vector: Network): The vulnerability can be exploited remotely over the network.
- AC:L (Attack Complexity: Low): The attack requires minimal skill or resources to exploit.
- PR:N (Privileges Required: None): No prior privileges are needed to exploit the vulnerability.
- UI:N (User Interaction: None): No user interaction is required for the attack to succeed.
- S:C (Scope: Changed): The vulnerability affects a component that is different from the one being exploited.
- C:H (Confidentiality: High): The vulnerability results in a high impact on confidentiality.
- I:H (Integrity: High): The vulnerability results in a high impact on integrity.
- A:N (Availability: None): The vulnerability does not impact the availability of the system.
2. Potential Attack Vectors and Exploitation Methods
The primary attack vector involves exploiting the Zero Touch Provisioning feature, which is designed to automate the configuration of network devices. An attacker could potentially:
- Intercept Network Traffic: Capture and manipulate network traffic related to ZTP to inject malicious configurations.
- Man-in-the-Middle Attack: Position themselves between the CloudVision system and the devices being provisioned to intercept and alter the provisioning process.
- Unauthorized Access: Gain unauthorized access to the CloudVision system by exploiting weaknesses in the ZTP process, leading to elevated privileges.
3. Affected Systems and Software Versions
The vulnerability affects the following versions of the CloudVision Portal:
- CloudVision Portal 2024.2.0 to 2024.2.1
- CloudVision Portal 2024.3.0
It is important to note that CloudVision as-a-Service is not affected by this vulnerability.
4. Recommended Mitigation Strategies
To mitigate the risk associated with this vulnerability, the following strategies are recommended:
- Update Software: Ensure that all affected systems are updated to the latest version of the CloudVision Portal that addresses this vulnerability.
- Network Segmentation: Implement network segmentation to isolate the CloudVision system from other parts of the network, reducing the attack surface.
- Monitor Network Traffic: Use intrusion detection systems (IDS) and intrusion prevention systems (IPS) to monitor network traffic for suspicious activity related to ZTP.
- Access Controls: Implement strict access controls and authentication mechanisms to prevent unauthorized access to the CloudVision system.
- Regular Audits: Conduct regular security audits and vulnerability assessments to identify and address potential security weaknesses.
5. Impact on European Cybersecurity Landscape
