Burp Suite 2020.5 (and probably 2020.4) crashes Brida plugin

Federico | Last updated: Jun 08, 2020 10:15AM UTC

Hi, one of mine plugin, Brida, stops working with Burp Suite 2020.4. I don't know if it is caused by Java version or by an update in Burp code. Brida starts a python service to do instrumentation on mobile applications. In the last version I can't get output from the python process nor killing the python service, because I obtain an exception. I can't understand why. I paste the exception I get: Exception shutting down Pyro server java.util.concurrent.ExecutionException: java.lang.ClassCastException: class java.lang.Integer cannot be cast to class java.lang.String (java.lang.Integer and java.lang.String are in module java.base of loader 'bootstrap') java.base/java.util.concurrent.FutureTask.report(FutureTask.java:122) java.base/java.util.concurrent.FutureTask.get(FutureTask.java:205) burp.BurpExtender.executePyroCall(BurpExtender.java:2726) burp.BurpExtender.actionPerformed(BurpExtender.java:3063) java.desktop/javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:1967) java.desktop/javax.swing.AbstractButton$Handler.actionPerformed(AbstractButton.java:2308) java.desktop/javax.swing.DefaultButtonModel.fireActionPerformed(DefaultButtonModel.java:405) java.desktop/javax.swing.DefaultButtonModel.setPressed(DefaultButtonModel.java:262) java.desktop/javax.swing.plaf.basic.BasicButtonListener.mouseReleased(BasicButtonListener.java:279) java.desktop/java.awt.Component.processMouseEvent(Component.java:6636) java.desktop/javax.swing.JComponent.processMouseEvent(JComponent.java:3342) java.desktop/java.awt.Component.processEvent(Component.java:6401) java.desktop/java.awt.Container.processEvent(Container.java:2263) java.desktop/java.awt.Component.dispatchEventImpl(Component.java:5012) java.desktop/java.awt.Container.dispatchEventImpl(Container.java:2321) java.desktop/java.awt.Component.dispatchEvent(Component.java:4844) java.desktop/java.awt.LightweightDispatcher.retargetMouseEvent(Container.java:4919) java.desktop/java.awt.LightweightDispatcher.processMouseEvent(Container.java:4548) java.desktop/java.awt.LightweightDispatcher.dispatchEvent(Container.java:4489) java.desktop/java.awt.Container.dispatchEventImpl(Container.java:2307) java.desktop/java.awt.Window.dispatchEventImpl(Window.java:2764) java.desktop/java.awt.Component.dispatchEvent(Component.java:4844) java.desktop/java.awt.EventQueue.dispatchEventImpl(EventQueue.java:772) java.desktop/java.awt.EventQueue$4.run(EventQueue.java:721) java.desktop/java.awt.EventQueue$4.run(EventQueue.java:715) java.base/java.security.AccessController.doPrivileged(AccessController.java:391) java.base/java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(ProtectionDomain.java:85) java.base/java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(ProtectionDomain.java:95) java.desktop/java.awt.EventQueue$5.run(EventQueue.java:745) java.desktop/java.awt.EventQueue$5.run(EventQueue.java:743) java.base/java.security.AccessController.doPrivileged(AccessController.java:391) java.base/java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(ProtectionDomain.java:85) java.desktop/java.awt.EventQueue.dispatchEvent(EventQueue.java:742) java.desktop/java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:203) java.desktop/java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:124) java.desktop/java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:113) java.desktop/java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:109) java.desktop/java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:101) java.desktop/java.awt.EventDispatchThread.run(EventDispatchThread.java:90) Thank you.
