CVSS: 8.8EPSS: 0%CPEs: 9EXPL: 0CVE-2022-21701 – Privileged Escalation in Istio
https://notcve.org/view.php?id=CVE-2022-21701
Istio is an open platform to connect, manage, and secure microservices. In versions 1.12.0 and 1.12.1 Istio is vulnerable to a privilege escalation attack. Users who have `CREATE` permission for `gateways.gateway.networking.k8s.io` objects can escalate this privilege to create other resources that they may not have access to, such as `Pod`. This vulnerability impacts only an Alpha level feature, the Kubernetes Gateway API. This is not the same as the Istio Gateway type (gateways.networking.istio.io), which is not vulnerable. • https://github.com/istio/istio/security/advisories/GHSA-mq8f-9446-c28r https://istio.io/latest/news/releases/1.12.x/announcing-1.12.2 • CWE-863: Incorrect Authorization •
CVSS: 9.8EPSS: 0%CPEs: 9EXPL: 0CVE-2022-21679 – Authorization Policy bypass in Istio
https://notcve.org/view.php?id=CVE-2022-21679
Istio is an open platform to connect, manage, and secure microservices. In Istio 1.12.0 and 1.12.1 The authorization policy with hosts and notHosts might be accidentally bypassed for ALLOW action or rejected unexpectedly for DENY action during the upgrade from 1.11 to 1.12.0/1.12.1. Istio 1.12 supports the hosts and notHosts fields in authorization policy with a new Envoy API shipped with the 1.12 data plane. A bug in the 1.12.0 and 1.12.1 incorrectly uses the new Envoy API with the 1.11 data plane. This will cause the hosts and notHosts fields to be always matched regardless of the actual value of the host header when mixing 1.12.0/1.12.1 control plane and 1.11 data plane. • https://github.com/istio/istio/security/advisories/GHSA-rwfr-xrvw-2rvv https://istio.io/latest/news/releases/1.12.x/announcing-1.12.2 • CWE-670: Always-Incorrect Control Flow Implementation •
