Disable X-Powered-By HTTP Header and Rename the Server Value for all Connectors (Scored)

Description

The xpoweredBy setting determines if Apache Tomcat will advertise its presence via the X-Powered-By HTTP header. It is recommended that this value be set to false. The server attribute overrides the default value that is sent down in the HTTP header further masking Apache Tomcat.

Rationale

Preventing Tomcat from advertising its presence in this manner may increase the complexity for attackers to determine which vulnerabilities affect the server platform.

Audit Procedure

Perform the following to determine if the server platform, as advertised in the HTTP Server header, has been changed:

Locate all Connector elements in $CATALINA_HOME/conf/server.xml.
Ensure each Connector has a server attribute and that the server attribute does not reflect Apache Tomcat. Also, make sure that the xpoweredBy attribute is NOT set to true.

Remediation

Perform the following to prevent Tomcat from advertising its presence via the X-Powered-By HTTP header.

Add the xpoweredBy attribute to each Connector specified in $CATALINA_HOME/conf/server.xml. Set the xpoweredBy attributes value to false.

<Connector
...
xpoweredBy="false" />

Alternatively, ensure the xpoweredBy attribute for each Connector specified in $CATALINA_HOME/conf/server.xml is absent.

Add the server attribute to each Connector specified in $CATALINA_HOME/conf/server.xml. Set the server attribute value to anything except a blank string.

Default Value

The default value is false.
