SV-81411r1_rule Oracle JRE 8 must set the option to enable online certificate validation.

Vulnerability discussion

Online certificate validation provides a real-time option to validate a certificate. When enabled, if a certificate is presented, the status of the certificate is requested. The status is sent back as “current”, “expired”, or “unknown”. Online certificate validation provides a greater degree of validation of certificates when running a signed Java applet. Permitting execution of an applet with an invalid certificate may result in malware, system modification, invasion of privacy, and denial of service.

Check content

If the system is on the SIPRNet, this requirement is NA. Navigate to the system-level “deployment.properties” file for JRE. /etc/.java/deployment/deployment.properties If the key “deployment.security.validation.ocsp=true” is not present in the deployment.properties file, this is a finding. If the key “deployment.security.validation.ocsp.locked” is not present in the deployment.properties file, this is a finding. If the key “deployment.security.validation.ocsp” is set to “false”, this is a finding.

Fix text

If the system is on the SIPRNet, this requirement is NA. Navigate to the system-level “deployment.properties” file for JRE. /etc/.java/deployment/deployment.properties Add the key “deployment.security.validation.ocsp=true” to the deployment.properties file. Add the key “deployment.security.validation.ocsp.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.
