Summary
Red Hat Security Advisory: Red Hat OpenShift Service Mesh 2.0.7.1 security update
Notes
Topic
An update for servicemesh and servicemesh-proxy is now available for OpenShift Service Mesh 2.0.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Red Hat OpenShift Service Mesh is Red Hat's distribution of the Istio service mesh project, tailored for installation into an on-premise OpenShift Container Platform installation.
Security Fix(es):
* envoyproxy/envoy: HTTP request with multiple value headers can bypass authorization policies (CVE-2021-32777)
* envoyproxy/envoy: HTTP request with a URL fragment in the URI can bypass authorization policies (CVE-2021-32779)
* envoyproxy/envoy: denial of service when using extensions that modify request or response sizes (CVE-2021-32781)
* istio/istio: HTTP request can bypass authorization mechanisms due to case insensitive host comparison (CVE-2021-39155)
* istio/istio: HTTP request with fragment in URI can bypass authorization mechanisms (CVE-2021-39156)

Details
Envoy is an open source L7 proxy and communication bus designed for large modern service oriented architectures. In affected versions envoy incorrectly handled a URI '#fragment' element as part of the path element. Envoy is configured with an RBAC filter for authorization or similar mechanism with an explicit case of a final "/admin" path element, or is using a negative assertion with final path element of "/admin". The client sends request to "/app1/admin#foo". In Envoy prior to 1.18.0, or 1.18.0+ configured with path_normalization=false. Envoy treats fragment as a suffix of the query string when present, or as a suffix of the path when query string is absent, so it evaluates the final path element as "/admin#foo" and mismatches with the configured "/admin" path element. In Envoy 1.18.0+ configured with path_normalization=true. Envoy transforms this to /app1/admin%23foo and mismatches with the configured /admin prefix. The resulting URI is sent to the next server-agent with the offending "#foo" fragment which violates RFC3986 or with the nonsensical "%23foo" text appended. A specifically constructed request with URI containing '#fragment' element delivered by an untrusted client in the presence of path based request authorization resulting in escalation of Privileges when path based request authorization extensions. Envoy versions 1.19.1, 1.18.4, 1.17.4, 1.16.5 contain fixes that removes fragment from URI path in incoming requests.
