A vulnerability in the Java Management Extensions (JMX) management agent included in the Java Runtime Environment (JRE) may allow a JMX client running on a remote host to perform unauthorized operations on a system running JMX with local monitoring enabled.
2. Contributing Factors
This issue can occur in the following releases for Windows, Solaris, and Linux:
This issue only affects systems where JMX is running with local monitoring enabled. To determine if JMX has local monitoring enabled, the following command can be run:
$ jstat -J-Djstat.showUnsupported=true -snap <pid> | grep "sun.management.JMXConnectorServer.address"
To determine the default version of the JRE that Internet Explorer uses:
The browser will display a page called "Installed plug-ins" which lists the version of the Java Plug-in as in the following example:
Java(TM) Plug-in 1.5.0_11-b03
This above example indicates the version of the JRE that the browser uses is 1.5.0_11.
There are no predictable symptoms that would indicate that the above issue has been exploited.
