Descriptions

The defaults settings for the CORS filter provided in Apache Tomcat 9.0.0.M1 to 9.0.8, 8.5.0 to 8.5.31, 8.0.0.RC1 to 8.0.52, 7.0.41 to 7.0.88 are insecure and enable 'supportsCredentials' for all origins. It is expected that users of the CORS filter will have configured it appropriately for their environment rather than using it in the default configuration. Therefore, it is expected that most users will not be impacted by this issue.

Las opciones por defecto para el filtro CORS proporcionado en Apache Tomcat 9.0.0.M1 a 9.0.8, 8.5.0 a 8.5.31, 8.0.0.RC1 a 8.0.52 y 7.0.41 a 7.0.88 son inseguras y permiten "supportsCredentials" para todos los orígenes. Se espera que los usuarios del filtro CORS lo tengan configurado de forma adecuada para su entorno, en lugar de emplearlo con su configuración por defecto. Por lo tanto, se espera que la mayoría de usuarios no se vean afectados por este problema.

Red Hat Fuse enables integration experts, application developers, and business users to collaborate and independently develop connected solutions. Fuse is part of an agile integration solution. Its distributed approach allows teams to deploy integrated services where required. The API-centric, container-based architecture decouples services so they can be created, extended, and deployed independently. This release of Red Hat Fuse 7.2 serves as a replacement for Red Hat Fuse 7.1, and includes bug fixes and enhancements, which are documented in the Release Notes document linked to in the References. Issues addressed include code execution, denial of service, deserialization, and traversal vulnerabilities.
