CVE-2020-13597

Calico nodes IPv6 traffic redirection from route advertisment

State: Published
Severity: 6.0 Medium
Published: Jun 3, 2020
Updated: Sep 16, 2024
Reserved: May 26, 2020

Description

Clusters using Calico (version 3.14.0 and below), Calico Enterprise (version 2.8.2 and below), may be vulnerable to information disclosure if IPv6 is enabled but unused. A compromised pod with sufficient privilege is able to reconfigure the node’s IPv6 interface due to the node accepting route advertisement by default, allowing the attacker to redirect full or partial network traffic from the node to the compromised pod.
