Vulnerability discussion

Decisions regarding the employment of mobile code within organizational information systems are based on the potential for the code to cause damage to the system if used maliciously. Mobile code is defined as software modules obtained from remote systems, transferred across a network, and then downloaded and executed on a local system without explicit installation or execution by the recipient.Usage restrictions and implementation guidance apply to both the selection and use of mobile code installed, downloaded, or executed on all endpoints (e.g., servers, workstations, and smart phones). This requirement applies to applications that execute, evaluate, or otherwise process mobile code (e.g., web applications, browsers, and anti-virus applications).

Check content

Navigate to the system-level "deployment.properties" file for JRE. \Sun\Java\Deployment\deployment.properties - or - \Lib\deployment.properties If the key "deployment.security.blacklist.check=true" is not present in the "deployment.properties" file, or is set to "false", this is a finding. If the key "deployment.security.blacklist.check.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. Add the key "deployment.security.blacklist.check=true" to the "deployment.properties" file. Add the key "deployment.security.blacklist.check.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.
