Vulnerability discussion

Java Web Start (JWS) applications are the most commonly used. Denying these applications could be detrimental to the user experience. Whitelisting, blacklisting, and signing of applications help mitigate the risk of running JWS applications.

Check content

Navigate to the system-level “deployment.properties” file for JRE. The location of the deployment.properties file is defined in \Lib\deployment.config If the key “deployment.webjava.enabled=true” is not present in the deployment.properties file, or is set to “false”, this is a finding. If the key “deployment.webjava.enabled.locked” is not present in the deployment.properties file, this is a finding. Note: If JWS is not enabled, this requirement is NA.

Fix text

Navigate to the system-level “deployment.properties” file for JRE. The location of the deployment.properties file is defined in \Lib\deployment.config Add the key “deployment.webjava.enabled=true” to the deployment.properties file. Add the key “deployment.webjava.enabled.locked” to the deployment.properties file. Note: If JWS is not enabled, this requirement is NA.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
