Apache Tomcat 8.5.0 < 8.5.8 multiple vulnerabilities
critical Nessus Plugin ID 95438

Synopsis
The remote Apache Tomcat server is affected by multiple vulnerabilitiesDescription
The version of Tomcat installed on the remote host is prior to 8.5.8. It is, therefore, affected by multiple vulnerabilities as referenced in the fixed_in_apache_tomcat_8.5.8_security-8 advisory.- Remote code execution is possible with Apache Tomcat before 6.0.48, 7.x before 7.0.73, 8.x before 8.0.39, 8.5.x before 8.5.7, and 9.x before 9.0.0.M12 if JmxRemoteLifecycleListener is used and an attacker can reach JMX ports. The issue exists because this listener wasn't updated for consistency with the CVE-2016-3427 Oracle patch that affected credential types. (CVE-2016-8735)
- The HTTP/2 header parser in Apache Tomcat 9.0.0.M1 to 9.0.0.M11 and 8.5.0 to 8.5.6 entered an infinite loop if a header was received that was larger than the available buffer. This made a denial of service attack possible. (CVE-2016-6817)
- The code in Apache Tomcat 9.0.0.M1 to 9.0.0.M11, 8.5.0 to 8.5.6, 8.0.0.RC1 to 8.0.38, 7.0.0 to 7.0.72, and 6.0.0 to 6.0.47 that parsed the HTTP request line permitted invalid characters. This could be exploited, in conjunction with a proxy that also permitted the invalid characters but with a different interpretation, to inject data into the HTTP response. By manipulating the HTTP response the attacker could poison a web-cache, perform an XSS attack and/or obtain sensitive information from requests other then their own. (CVE-2016-6816)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Upgrade to Apache Tomcat version 8.5.8 or later.See Also
