Subject [jira] [Commented] (PIVOT-965) Java 8 BXML scripting security issues in Apache Pivot RIAs

Roger Whitcomb commented on PIVOT-965:
--------------------------------------

Okay, so we ran into another of the same issues in a different place in our application. 
I have applied the fixes made to ElementInvocationHandler to ScriptBindMapping, and this resolves
this latest issue.  Also had to add the Nashorn compat script evaluation in another place
-- feels like this is just a case of the wrong scope being use, or something, because I'm
already doing this eval in the "getEngineByxxx" method that it calls, but ...  At any rate,
the problem is resolved now.

Looks like "branches/2.0.x" hasn't gotten earlier changes either, so I'm not going to merge
this right away until I get things straightened out.

> We encounter security issues in our pivot application after upgrading to JRE 1.8. The
application is deployed as RIA using Java Web Start.
> I found out, that the problem is connected with nashorn script engine which replaced
rhino script engine from previous java version. BXMLSerializer is using ScriptEngine to evaluate
scripts in BXML files. It seems, that all calls initiated from BXML scripts, are considered
untrusted in JRE 1.8 RIA Environment - this means security dialogs and exceptions are thrown,
when trying execute privileged actions (network communication, reflection ...).
> Currently, I am not sure, if this is Pivot or Nashorn bug, but it is problem for current
Apache Pivot RIAs. To investigate the srcipting behaviour in RIAs, I created testing non Pivot
project https://github.com/kaja78/jnlpScripting The project contains testing application,
which is deployed as JWS. When you execute the java web start app in JRE 1.8, the security
dialog is displayed when testing method is executed from nashorn script engine (if you press
cancel button on security dialog, you get SecurityException). When you uncomment 2 lines in
Webcontent/jnlpScripting.jnlp file, rhino script engine is used instead of nashorn and no
security dialog is displayed. This fix works also for our Pivot RIAs.
> I believe, Pivot should work in JRE 1.8 RIA Environment without security issues by default,
so it should be fixed somehow in Pivot - may be, by correct ScriptEngine configuration in
BXMLSerializer or by including Rhino libraries in Pivot distribution. Any idea how to "correctly"
fix this issue?
> Btw.: I found this bug: http://bugs.java.com/view_bug.do?bug_id=8045075 I am not sure,
if it is the same problem. But anyway, it should be fixed in
> 1.8.25.b01 and we are encountering above issues in latest 1.8.0.31.b13.
