Hello! Missing HSTS is not a vulnerability, as Mark pointed out, it is a feature. In your web.xml
<filter> <filter-name>httpHeaderSecurity</filter-name> <filter-class>org.apache.catalina.filters.HttpHeaderSecurityFilter</filter-c lass> <init-param> <param-name>hstsEnabled</param-name> <param-value>true</param-value> </init-param> <init-param> <param-name>hstsMaxAgeSeconds</param-name> <param-value>31536000</param-value> </init-param> <init-param> <param-name>hstsIncludeSubDomains</param-name> <param-value>true</param-value> </init-param> <async-supported>true</async-supported> </filter> This will NOT activate HSTS for your application, you will need to add this mapping as well (edit to needs and add to application): <filter-mapping> <filter-name>httpHeaderSecurity</filter-name> <url-pattern>/*</url-pattern> <dispatcher>REQUEST</dispatcher> </filter-mapping> Regards, Harrie -----Original Message----- From: dku...@ccilindia.co.in [mailto:dku...@ccilindia.co.in] Sent: maandag 8 februari 2016 15:50 To: 'Tomcat Users List' <users@tomcat.apache.org> Subject: HSTS missing from HTTPS server on tomcat 8.0.27 Hi, We are unable to fix the vulnerability of "HSTS missing from HTTPS server" on apache tomcat 8.0.27 while running on unix operating system. Below is the system configuration: OS Name: HP-UX OS Version: B.11.31 Architecture: IA64N Java Home: /opt/java8/jre JVM Version: 1.8.0.04-hp-ux-b2 JVM Vendor: Hewlett-Packard Company We have uncommented the httpHeaderSecurity in the filter tag of conf/web.xml file, but still the vulnerability exists. We have also tried with apache tomcat 8.0.30, but in vain. Any help to fix this vulnerability is appreciated.
