CVE-2016-6797 Apache Tomcat Unrestricted Access to Global Resources Severity: Low
Vendor: The Apache Software Foundation Versions Affected: Apache Tomcat 9.0.0.M1 to 9.0.0.M9 Apache Tomcat 8.5.0 to 8.5.4 Apache Tomcat 8.0.0.RC1 to 8.0.36 Apache Tomcat 7.0.0 to 7.0.70 Apache Tomcat 6.0.0 to 6.0.45 Earlier, unsupported versions may also be affected. Description The ResourceLinkFactory did not limit web application access to global JNDI resources to those resources explicitly linked to the web application. Therefore, it was possible for a web application to access any global JNDI resource whether an explicit ResourceLink had been configured or not. Mitigation Users of affected versions should apply one of the following mitigations - Upgrade to Apache Tomcat 9.0.0.M10 or later - Upgrade to Apache Tomcat 8.5.5 or later - Upgrade to Apache Tomcat 8.0.37 or later - Upgrade to Apache Tomcat 7.0.72 or later (Apache Tomcat 7.0.71 has the fix but was not released) - Upgrade to Apache Tomcat 6.0.47 or later (Apache Tomcat 6.0.46 has the fix but was not released) Credit: This issue was discovered by the Apache Tomcat Security Team.
