LOWCVSS 3.5/10EPSS 0.90%

Last modified

CVE-2020-13597 is a low-severity vulnerability rated 3.5/10 on the CVSS scale. 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.. EPSS estimates a 0.90% chance of exploitation in the next 30 days.
