Security Vulnerability in the Java Runtime Environment May Allow Untrusted JavaScript Code to Elevate Privileges Through Java APIs

1. Impact

A vulnerability in the Java Runtime Environment may allow JavaScript code that is downloaded by a browser to make connections to network services on the system that the browser runs on, through Java APIs. This may allow files (that are accessible through these network services) or vulnerabilities (that exist on these network services) which are not otherwise normally accessible to be accessed or exploited.

Sun acknowledges with thanks, Gregory Fleischer and Mozilla for bringing this issue to our attention.

2. Contributing Factors

This issue can occur in the following releases running Firefox 2.0.0.12 and earlier:

• JDK and JRE 6 Update 4 and earlier
• JDK and JRE 5.0 Update 14 and earlier
• SDK and JRE 1.4.2_16 and earlier

Note: This issue does not occur on all versions of Internet Explorer.

To determine the version of Firefox in use, visit the URL "about:plugins".

To determine the default version of the JRE that Firefox browsers use, visit the URL "about:plugins". The browser will display a page called "Installed plug-ins" which lists the version of the Java Plug-in such as the following:


The above indicates the version of the JRE the browser uses is 1.5.0_11.

3. Symptoms

There are no predictable symptoms that would indicate that the above issue is being exploited.
