A flaw was found in Apache Tomcat. When responding to new h2c connection requests, Apache Tomcat could duplicate request headers and a limited amount of request body from one request to another meaning user A and user B could both see the results of user A's request. The highest threat from this vulnerability is to data confidentiality.

Red Hat Jboss Fuse 6 ships some of the vulnerable artifacts as bundled artifacts in ops4j pax web, however there is no use of these artifacts in Fuse itself, the artifacts are also prevented from loading with a deny list in karaf, for these reasons we believe the impact upon Fuse 6.3 is low. The same also applies to Red Hat Fuse 7. This vulnerability is out of security support scope for the following products: * Red Hat JBoss Fuse 6 Please refer to https://access.redhat.com/support/policy/updates/jboss_notes for more details. Statement: Red Hat Enterprise Linux 8's Identity Management and Certificate System are using a vulnerable version of Tomcat that is bundled into the `pki-servlet-engine` component. However, HTTP/2 is not enabled in such a configuration, and it is not possible to trigger the flaw in a supported setup. A future update may fix the code. Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 7 are not affected by this flaw because HTTP/2 is not supported in the shipped version of tomcat in those packages. Red Hat OpenStack Platform's OpenDaylight will not be updated for this flaw because it was deprecated as of OpenStack Platform 14 and is only receiving security fixes for Important and Critical flaws. This issue has been addressed in the following products: Red Hat JBoss Web Server Via RHSA-2021:2562 https://access.redhat.com/errata/RHSA-2021:2562 This issue has been addressed in the following products: Red Hat JBoss Web Server 5.5 on RHEL 7 Red Hat JBoss Web Server 5.5 on RHEL 8 Via RHSA-2021:2561 https://access.redhat.com/errata/RHSA-2021:2561 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-2021-25122 This issue has been addressed in the following products: Red Hat support for Spring Boot 2.3.10 Via RHSA-2021:3425 https://access.redhat.com/errata/RHSA-2021:3425 This issue has been addressed in the following products: Red Hat Fuse 7.11 Via RHSA-2022:5532 https://access.redhat.com/errata/RHSA-2022:5532 |
