Java blocking untrusted applications

Application Blocked by Java Security – SAP PI ESR

I will try to document the solution to one of the errors which occured in my environment when logging in to the Process Integration (PI) Enterprise Services Repository (ESR) or Integration Builder tools for Java Web Start software version 7 and 8.

Supported Java Web Start Versions:

SAP PI 7.4 >= SP08

For older release and much more please refer to below wiki

Here in my environment we have recently upgraded our JAVA version to 1.8

After upgrading whenever we were trying to open ESR we were getting below error

Java 7u10 introduced the ability to manage when and how untrusted Java applications (i.e. an application that is digitally signed by an unknown publisher, or a certificate that has not been issued by a trusted Certificate Authority) will run if they are included on a web page. Setting the security level within the Java Control Panel will determine whether

1. You are prompted before an untrusted java application is run (MEDIUM or HIGH) or
2. Untrusted Java applications will be blocked so they cannot run (VERY HIGH).

Starting with Java 7 Update 51, applets that do not conform with the latest security practices can still be authorized to run by including the sites that host them to the Exception Site List.

Starting with Java 8 Update 20, the Medium security level has been removed from the Java Control Panel. Only High and Very High levels are available.

The exception site list provides users with the option of allowing the same applets that would have been allowed by selecting the Medium option but on a site-by-site basis therefore minimizing the risk of using more permissive settings.

How to configure exception list

The Exception Site List feature was introduced in the release of Java 7 Update 51. By adding application URL to the Exception list allows users to run Rich Internet Applications (RIAs) that would normally be blocked by security checks.

The exception site list is managed in the Security tab of the Java Control Panel. To add, edit or remove a URL from the list, click Edit Site List as shwon below:

Open the Java Control Panel using command \javaws -viewer from command prompt or from Start–>Run.If you have it added in your PATH variable then no need to provide the Full Path.

It will open a Window like this:-

Java Control Panel – Java 8

• Click on the Edit Site List button.

• Click the Add in the Exception Site List window.
• Click in the empty field under Location field to enter the URL. In mycase I added http:// /:500.If you notice that your ESR is using FQDN then you have to provide FQDN here.Remember Wildcards are not supported here.
• Click OK to save the URL that you entered. If you click Cancel, the URLs are not saved.
• Click Continue on the Security Warning dialog.

You can Remove, Edit any URL using above method.

Now try to open ESR and it should open now.

How to Fix Application Blocked by JAVA Security? (2 Fixes)

Several users are encountering the “Your security settings have blocked an untrusted application from running” when trying to launch a Java applet. The issue doesn’t seem to be exclusive to a certain Windows version – the error is encountered with every recent version including Windows Vista, Windows 7, Windows 8 and Windows 10.

What causes Security Settings to Block Applications from Running?

We investigated the “Your security settings have blocked an untrusted application from running” error by looking at various user reports and the repair strategies that they used.

As it turns out, the error prompt will occur due to Java browser plug-in behavior introduced with Java 7 Update 21. The idea was to allow users to make more informed decisions when having to run a Java-powered applet inside a web browser.

If you have Java 7 Update 21 or older, any application that doesn’t have a certificate or is missing the Application name or the Publisher information is blocked by default. This decision was made to protect unsuspecting users from unsafe or high-risk applications.

Once these new changes enforced, there are three main causes that will trigger this particular Java error message:

• The application is unsigned – Applications without a certificate or missing Publisher Information and Name are blocked by default. These might end up making your system vulnerable to external exploits.
• The user is trying to run a self-signed application from an untrusted authority – Applications with self-signed certificates are also blocked by default starting with Java 7 Update 51. These are considered even more dangerous than unsigned applications since they might be granted access to personal data on your computer.
• Application’s jar file is missing a permission attribute – The permission attribute verifies if the application request uses the same permission level that was specified by the developer. An application with a missing jar attribute is blocked because an attacker might exploit the user by running the application with a different privilege level.

In general, an Applet or application that is missing these key identification parts should be considered unsafe. If you don’t know it, we highly recommend that you avoid running it.

However, if you know the publisher and you trust the applet (e.g. you developed it yourself or you’re testing it) there are ways to circumvent this particular error message.

Below you have a couple of methods that will allow you to deal with the “Your security settings have blocked an untrusted application from running” error. Although Method 1 is widely considered as standard practice when having to deal with this particular error message, you can also follow Method 2 to achieve the same purpose.

Method 1: Configuring the Exception Site List

In the event that you do understand the risk of launching an application that is considered unsafe by Java, you can prevent the “Your security settings have blocked an untrusted application from running” error message from appearing by adding the application to the Exception Site List. You can find this setting under the Security tab of the Java Control Panel.

Here’s a quick guide on opening the Java Control Panel and adding the Java applet to the Exclusion Site List:

1. Press Windows key + R to open up a Run dialog box. Then, type “control” and press Enter to open Control Panel.
2. Inside the Control Panel window, click on Programs, then click on the Java icon to open the Java Control Panel.
   
3. Inside the Java Control Panel window, go to the Security tab and click on the Edit Site List.
4. Inside the Exception Site list, click on Add button, then paste the URL of the Java applet that is giving you troubles. Hit Ok to add the URL to the Exclusion list. Note: Keep in mind that depending on which applet you’re trying to run, you might also need to add non-standard ports to the Java Exclusion List.
5. Click Continue at the next Security Warning to confirm that you want to add the URL that you’ve just entered to the exclusion list.
6. Re-open the applet that was previously showing the error. The error should no longer be occurring.

If you’re looking for a different way of resolving the “Your security settings have blocked an untrusted application from running” error, move down to the next method below.

Method 2: Setting the Security level of application to High

Another way to go around resolving the “Your security settings has blocked an untrusted application from running” error is to set the Java Security level to High instead of Very High.

While this method is way easier (and quicker) to implement, it will expose your computer to many potential risks. With this in mind, it’s preferable to follow Method 1 if you trust the source than to modify the security level.

However, if you decide to do it, we encourage you to revert to the default Security Settings level once you are done using the Java application that is triggering the error.

Here’s a quick guide o how to modify the Security Level:

1. Press Windows key + R to open up a Run dialog box. Next, type “control” and press Enter to open Control Panel.
2. Inside the Control Panel window, click on Programs, then click on the Java icon to open the Java Control Panel.
   
3. Inside the Java Control Panel window, go to the Security tab and select the High toggle from under the Security level for applications, not on the Exception Site List. Then, click Apply to save the changes.
4. Restart the browser that you’re running the applet in and see if the issue has been resolved once you reload the page.
