Looking at the binary from here: http://cxf.apache.org/download.html apache-cxf-3.4.3]$ grep -r JwtRequestCodeFilter Binary file lib/cxf-rt-rs-security-oauth2-3.4.3.jar matches That makes sense given that it's a DoS in the OAuth service. Based on this OpenShift products do not package cxf-rt-rs-security-oauth2 at all, so marking logging-elasticsearch containers as not affected. External References: https://cxf.apache.org/security-advisories.data/CVE-2021-22696.txt.asc I believe the upstream fix is to disable request_uri: - https://github.com/apache/cxf/commit/7d5d2c7a019dd1e1d0566daf9f1ed5b7b0dd66b7 Especially given: This method must be overridden to support request_uri. Take care to validate the request_uri properly, * as otherwise it could lead to a security problem * (https://tools.ietf.org/html/draft-ietf-oauth-jwsreq-30#section-10.4) And possibly also to ensure both request_uri and request can't exist together: - https://github.com/apache/cxf/commit/aee3bf291a7387cc492aa0dbdb0fb2af96687994 Addition to comment #1 OpenShift 3.11 openshift3/ose-logging-elasticsearch5 does not have any reference to the cxf package and hence isn't added to the affects whiteboard, just openshift 4. This issue has been addressed in the following products: Red Hat Fuse 7.10 Via RHSA-2021:5134 https://access.redhat.com/errata/RHSA-2021:5134 This bug is now closed. Further updates for individual products will be reflected on the CVE page(s): https://access.redhat.com/security/cve/cve-2021-22696 Issue persists with fuse - 3.3.6.fuse-7_10_0-00022-redhat-00001. Can someone confirm if the issue was resolved? This issue has been addressed in the following products: JWS 5.7.0 Via RHSA-2022:7273 https://access.redhat.com/errata/RHSA-2022:7273 |
