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

The cybersecurity world has recently been alerted to a critical vulnerability, CVE-2024-11186, that affects the Arista CloudVision Portal products when run on-premise. This vulnerability, due to improper access controls, could enable a malicious authenticated user to execute broader actions on managed EOS devices than intended. This situation is particularly grave because it has the potential to cause system<\/a> compromise or data leakage. The issue is of utmost importance to organizations using Arista’s CloudVision on-premise as it could lead to unauthorized access and manipulation of sensitive data<\/a>.<\/p>\n

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

CVE ID: CVE-2024-11186
\nSeverity: Critical, CVSS score 10.0
\nAttack Vector: Network
\nPrivileges Required: Low
\nUser Interaction: Required
\nImpact: Potential system<\/a> compromise or data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

Arista CloudVision<\/a> Portal | All on-premise versions prior to the patch<\/p>\n

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

The exploit takes advantage of improper access controls<\/a> in the CloudVision portal. A malicious user, once authenticated, can potentially manipulate the EOS devices’ settings or access sensitive information<\/a>. The exploit could allow unauthorized access to device configurations, network settings, and potentially sensitive data<\/a> stored or transmitted through these devices. This vulnerability is particularly concerning because it enables a malicious user to gain control<\/a> over managed EOS devices, which can lead to severe consequences such as system compromise or data leakage.<\/p>\n

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

This is a conceptual example of how a malicious authenticated user might exploit the vulnerability:<\/a><\/p>\n

# Assumed authenticated session\n$ curl -X POST \"http:\/\/target.example.com\/api\/eos-config\" \\\n-H \"Content-Type: application\/json\" \\\n-d '{\n\"config\": {\n\"command\": \"config t\",\n\"action\": \"configure terminal\",\n\"parameter\": \"no ip access-list extended ACL-IN\"\n}\n}'<\/code><\/pre>\n
In this example, the command removes an IP access list, potentially opening up the network<\/a> for further exploitation.
\nIt is worth noting that this is a conceptual example and the actual exploit might differ based on the specific configurations and settings of the EOS devices<\/a>.<\/p>\n
How to Mitigate<\/strong><\/p>\n
The recommended mitigation is to apply the vendor patch as soon as possible. In case the patch cannot be applied immediately, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) may serve as a temporary mitigation. These tools can help monitor network traffic and detect any suspicious activities that might indicate an attempted exploit of this vulnerability<\/a>. Regularly monitoring system logs<\/a> for any unusual activities can also aid in early detection.<\/p>\n","protected":false},"excerpt":{"rendered":"
