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. ## Affected - `tomcat >= 7.0.41, <= 7.0.88` - `tomcat >= 8.0.0, <= 8.0.52` - `tomcat >= 8.5.0, <= 8.5.31` - `tomcat >= 9.0.0, <= 9.0.8` - `tomcat = 8.0.0` - `tomcat = 9.0.0` - `ubuntu_linux = 14.04` - `ubuntu_linux = 16.04` - `ubuntu_linux = 17.10` - `ubuntu_linux = 18.04` - `debian_linux = 8.0` - `oncommand_insight` - `oncommand_unified_manager >= 9.4` - `oncommand_workflow_automation` - `snapcenter_server` - `storage_automation_store` - `oncommand_unified_manager >= 7.3` ## Remediation Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
