[richfaces-issues] [JBoss JIRA] Closed: (RF-4712) hidden field javax.faces.ViewState is not sanitized

hidden field javax.faces.ViewState is not sanitized --------------------------------------------------- Key: RF-4712 URL: https://jira.jboss.org/jira/browse/RF-4712 Project: RichFaces Issue Type: Bug Affects Versions: 3.2.2 Environment: jsf-ri 1.2_09-BETA1, WindowsXP, Firefox 3.0.0.3 Reporter: Gerrit Brehmer Assignee: Viktor Volkov Sorry for duplicating the old bug, but I think he had the same problem... We had a Security Audit of our Web Portal and they found a possible Cross Site Scripting Problem: If I attach the following at any JSF site url I get a javascript popup: ?AJAXREQUEST=&javax.faces.ViewState=j_id1s"/><img+src=XX+onerror=alert(1)> I know that we could filter each request.
