Rancher 2 through 2.2.4 Cross-Site Websocket Hijacking Vulnerability

CVE-2019-13209 · MEDIUM Severity

AV:N/AC:M/AU:N/C:N/I:P/A:N

Rancher 2 through 2.2.4 is vulnerable to a Cross-Site Websocket Hijacking attack that allows an exploiter to gain access to clusters managed by Rancher. The attack requires a victim to be logged into a Rancher server, and then to access a third-party site hosted by the exploiter. Once that is accomplished, the exploiter is able to execute commands against the cluster's Kubernetes API with the permissions and identity of the victim.
