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. /etc/.java/deployment/deployment.properties 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.

Fix text

Navigate to the system-level “deployment.properties” file for JRE. /etc/.java/deployment/deployment.properties Add the key “deployment.webjava.enabled=true” to the deployment.properties file. Add the key “deployment.webjava.enabled.locked” to the deployment.properties file.

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.
