Original date: 26.07.2018
\nOverall risk classification: HIGH<\/span> <\/p>\n

Overview<\/h3>\n

Apache has published updates fixing two severe security issues in all active branches of Tomcat.
\nOne of these vulnerabilities may lead to user sessions being reused in a new connection, therefore disclosing information [1].
\nThe second vulnerability can be exploited if an overflow in the UTF-8 decoder happens. This will possibly result in an infinity loop and therefor in a Denial of Service [2].<\/p>\n

Systems Affected<\/h3>\n

All Tomcat systems prior to 9.0.9, 8.5.31, 8.0.51 or 7.0.86 [1, 2].<\/p>\n

Threat<\/h3>\n

Risk<\/strong>: HIGH<\/span>
\nIf your project operates a Tomcat web server in a vulnerable version, unauthorised users may be able to gather information or endanger the availability of the project.
\nExploitability<\/strong>: MEDIUM<\/span>
\nPrerequisite for both attacks is improper handling of untrusted user input. An attacker has to send a request with malicious data
\nPriority<\/strong> (for affected, internet-exposed systems): HIGH<\/span>
\nPriority<\/strong> (for internal systems): MEDIUM<\/span> <\/p>\n

Mitigation<\/h3>\n

If you deploy Apache Tomcat servers directly, update your systems to the latest version (9.0.10, 8.5.32, 8.0.52 or 7.0.90 [3, 4, 5]. If you rely on software which bundles a Tomcat server internally (Hybris, for instance), look out for updates of this software. <\/p>\n
