Because security constraints defined in this way apply to the URL pattern and any URLs below that point, it was possible - depending on the order Servlets were loaded - for some security constraints not to be applied. This could have exposed resources to users who were not authorised to access them. ## Affected - `tomcat >= 7.0.0, <= 7.0.84` - `tomcat >= 8.0.0, <= 8.0.49` - `tomcat = 8.0.0` - `tomcat = 9.0.0` - `tomcat = 9.0.1` - `tomcat = 9.0.2` - `tomcat = 9.0.3` - `tomcat = 9.0.4` - `tomcat >= 8.5.0, <= 8.5.27` - `debian_linux = 7.0` - `debian_linux = 8.0` - `debian_linux = 9.0` - `ubuntu_linux = 14.04` - `ubuntu_linux = 16.04` - `ubuntu_linux = 17.10` - `ubuntu_linux = 18.04` - `fusion_middleware = 12.2.1.3.0` - `managed_file_transfer = 12.1.3.0.0` - `managed_file_transfer = 12.2.1.3.0` - `micros_relate_crm_software = 11.4` ## Remediation Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
