Attack-Flow Graph

Executive Summary

VMware Avi Load Balancer has an authentication bypass vulnerability. This means a malicious user with network access could bypass the authentication mechanism and gain unauthorized access to the Avi Control plane.

Detection Guidance

This vulnerability allows bypassing authentication in VMware Avi Load Balancer. To detect it, check the version of your Avi Load Balancer. If it is between 31.1.1-31.2.2, 30.1.1-30.2.6, or 22.1.1-22.1.7, it is vulnerable. Verify if the version is below the fixed versions (31.2.2-2p3, 30.2.7, or 30.2.7 respectively).

Impact Analysis

An attacker could exploit this to take control of the load balancer, potentially intercepting or manipulating network traffic, leading to data breaches or service disruptions.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating compliance requirements for GDPR, HIPAA, and other regulations that mandate strict access controls and data protection.

Mitigation Strategies

Immediately upgrade affected VMware Avi Load Balancer versions to the fixed releases: 31.2.2-2p3, 30.2.7, or 22.1.7. Isolate the system from untrusted networks if patching is delayed.
