Summary
Red Hat Security Advisory: Red Hat OpenShift Service Mesh 1.1.17.1 security update
Notes
Topic
An update for servicemesh and servicemesh-proxy is now available for OpenShift Service Mesh 1.1.
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)

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)

Vulnerability from gsd

Details
Envoy is an open source L7 proxy and communication bus designed for large modern service oriented architectures. In affected versions when ext-authz extension is sending request headers to the external authorization service it must merge multiple value headers according to the HTTP spec. However, only the last header value is sent. This may allow specifically crafted requests to bypass authorization. Attackers may be able to escalate privileges when using ext-authz extension or back end service that uses multiple value headers for authorization. A specifically constructed request may be delivered by an untrusted downstream peer in the presence of ext-authz extension. Envoy versions 1.19.1, 1.18.4, 1.17.4, 1.16.5 contain fixes to the ext-authz extension to correctly merge multiple request header values, when sending request for authorization.
