Managing Java browser plug-in settings for Apple’s XProtect malware protection

February 24, 2013 10 comments

In response to a number of recent Java exploits, both Apple and Mozilla have begun blocking vulnerable versions of Java from running in their respective browsers via their malware protection mechanisms. While this is the right move from a security perspective, it can leave enterprises without the ability to access mission-critical systems that use Java applets running in a browser.

The fix should be to update those affected machines with the latest version of Java. However, this assumes that a) the latest available version of Java is not itself blocked and b) the mission-critical system is able to use the latest version of Java.

From my own perspective, what Apple is doing from a malware protection standpoint is the right thing. I just don’t want my users to lose the ability to access our systems that use a Java applet, especially when the latest available version of Java is blocked and I don’t have a way to otherwise satisfy Apple’s XProtect malware protection without disabling XProtect.

My fix was this: manage XProtect’s ability to disable the Java browser plug-in by modifying the Java browser plug-in settings in the affected Mac’s /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/XProtect.meta.plist file. See below the jump for the details.
