CVE-2022-0552Network attack vector

Request smuggling via retained vulnerable Netty parser

Published Apr 11, 2022 · Updated Aug 2, 2024

HTTP request smuggling in Red Hat OpenShift Logging 3.11 allows remote attackers to poison proxied HTTP/1.1 requests. The Elasticsearch 6 container retains a vulnerable Netty HTTP codec that fails to validate Content-Length when one HTTP/2 headers frame ends the stream before translation. Exploitation requires a proxy path that translates attacker-controlled HTTP/2 requests to HTTP/1.1, allowing request-boundary confusion and downstream request injection.
