The following URL displaying the source code of the file, which one my customer reported as a vulnerability.

https://xxxxx:16311/ibm/help/ver362.3/advanced/tocView.JSP, it is happing only on windows operating system only. 

It seems to be happening only with uppercase "JSP" extension. Could you please have a look into this and update us ASAP.

Comment 8 Dani Megert CLA 2017-11-29 12:11:57 EST
This might happen due to a wrong configuration of the Help server (just a guess).

Out of the box (e.g. with http://download.eclipse.org/eclipse/downloads/drops4/S-4.8M3a-201710300400/) I cannot reproduce the problem but I can reproduce launching a target workspace out of my IDE workspace.

Test Case (for Windows):
1. Start Eclipse (used 4.8 M3a) with a new workspace
2. Import 'org.eclipse.help.webapp' from the target or Git
3. Start a new Eclipse Application and in there:
  4. In the Help preferences choose the external browser to open help contents
  5. Help > Help Contents
  6. In the browser's location field replace "index.jsp" with "advanced/tocView.JSP" (note the uppercase file extension)

==> The JSP source will be displayed. This happens for all JSPs.

This happens with Firefox and IE.


If 'org.eclipse.help.webapp' is removed, the problem does not appear.

From my preliminary investigation, I have seen that the difference between using the jar file and the imported jar plugin is that, in the Class
org.eclipse.osgi.storage.Storage the bundle file(org.eclipse.osgi.storage.bundlefile.BundleFile) used is different in both the cases

1) For the jar file the Bundle file is org.eclipse.osgi.storage.bundlefile.ZipBundleFile which does a case sensitive search for the file using java.util.zip.ZipFile and therefore does not find the file "advanced/tocView.JSP" 

2) For the imported plugin directory, the Bundle file used is
org.eclipse.osgi.storage.bundlefile.DirBundleFile which uses java File.exists() which is case insensitive and therefore finds the file "advanced.tocView.JSP"
Comment 10 Eclipse Genie CLA 2017-12-11 09:19:13 EST
New Gerrit change created: https://git.eclipse.org/r/113164
Comment 11 Kalyan Prasad Tatavarthi CLA 2017-12-13 22:47:48 EST
Here is the current behavior of Help webapp

There are two extension points that act on the content of the 'advanced' folder

1) A servlet extension point  which handles '/advanced/*.jsp' files.
2) A resource extension point which handles '/advanced' folder -> that is all files in the advanced folder.

a) Now a search for '/advanced/tocView.jsp' matches the 1st extension point . So the servlet is processed and served correctly.

b) A search for '/advanced/tocView.JSP' does not match the 1st extension point , but matches the second extension point.
	Now a search is made for a resource named 'tocView.JSP' in the advanced folder.
	i)   If the jar file was being used, as stated before, the search is case sensitive and therefore no file is found.
	ii)  If the plugin is used, the search is case insensitive and the file is found and as a resource, the content of the file is sent.

c) A search for '/advanced/indexView.js' does not match the 1st extensionpoint, but matches the second extension point.
	Now a search is made for a resource named 'indexView.js' in the advanced folder.
	in both the cases either using a plugin or a jar, the file is found and as a resource the content of the file is sent.
Comment 12 Kalyan Prasad Tatavarthi CLA 2017-12-13 23:00:00 EST
The Gerrit change: https://git.eclipse.org/r/113164
handles this case as described below.

In the patch provided:
The Resource extension point for advanced folder has been modified to advanced/images folder

Servlet extensions for  
1) advanced/*.js
2) advanced/*.css
3) advanced/*.html

have been created and a new class 'FilterCallsServlet' is created to handle these requests 

The filter is based on whether the HttpServletRequest has a referrer and coming from within the help path.

The Remaining code which handles the reading the resource content is taken from org.eclipse.equinox.http.servlet.internal.servlet.ResourceServlet 

This fixes
1) calls to advanced/*.JSP does not match any of the extensions, so the resource is not found
2) calls to advanced/*.js matches the new extension which is filtered by FilterCallsServlet and allows only those calls called from within help and not the direct calls.

@tjwatson Does equinox provide a way to handle non jsp files?
If so then we could use that instead of replicating Equinox code here.

Is this also considered an issue?  I don't think the serving up of the *.js resources can be considered an Equinox issue.  It is doing exactly what the extensions told it to do in this case.

See bug 395274.  If you have this kind of setup with an exploded app jar then you will need to set the following config property to ensure string checking of the resource name case for DirBundleFile

    osgi.strictBundleEntryPath=true

Set this property in the configuration/config.ini file or you can set it as a -D option in the eclipse.ini file as a separate line after the -vmargs line:

-Dosgi.strictBundleEntryPath=true

Sravan, can you add that please.


What about the *.js where the source is shown? What should be add to plugin.xml?

I have tried both the options
In the Eclipse install directory
1)add the line 
osgi.strictBundleEntryPath=true
in a new line in the file configuration/config.ini

(or)

2) add the -option -Dosgi.strictBundleEntryPath=true in the file eclipse.ini in a new line after -vmargs

And using any of these options fixes this issue. Thanks Thomas.

This is considered an issue if a direct call to 
http://127.0.0.1:PORTNUMBER/help/advanced/indexView.js

displays the file content.

The correct behavior would be that this call should be allowed from within help context but not directly. So is there a way by which equinox provides this facility?

If the resources are not meant to be access externally then why place them in a folder that is being used to serve resources externally?  For resources you need to read internally why go through the http service layer at all?  Why not just read the resource locally using things like getResource?

There is nothing I'm aware of built into equinox to do what you are wanting.

Hi Kalyan,

I have tried the following suggestion,

add the line 
osgi.strictBundleEntryPath=true
in a new line in the file configuration/config.ini

It seems to be not fixed our issue. Could you please suggest us on further actions.

We can add this to our ini file but I don't think that will help. The inin files are specific to products. We will be adding this to platform, sdk and equinox products. but the this won't affect epp or IES products

Hi Kalyan,

I have tried to upgrade eclipse to resolve this issue based on our discussion. But as per my understand the eclipse help jar which we are using is latest (org.eclipse.help.base_3.6.101.v201301310800.jar ) and not able to move further on this issue and it is becoming aged PMR. 

Could you please help us on this, until the issue get resolve.

The *.js files are downloaded as references and it is normal to be able to see them.
What we could do, is to minify these *.js files and then use the minified *.js files, which would make reading  of the *.js files difficult
