Grouper UI csrf xsrf prevention Wiki Home Download Grouper Grouper Guides Community Contributions Developer Resources Grouper Website This is in Grouper 2.2 UI. btw, Ive heard this does not work with IE8. Logging Set this in log4j.properties for enhanced logging log4j.logger.edu.internet2.middleware.grouper.grouperui.csrf.csrfguardlogg er = DEBUG Legacy instructions These instructions install OWASP CSRF guard in the Grouper UI. These instructions are intended for Grouper v2.1, though it will probably work on v2.0, and could be adapted for previous versions as well. 1. Download the jar, note, this is from the mchyzer github clone 1.5. If you have Grouper UI v2.1.5 or less, then add this logging jar. Note, remember on upgrade to remove this temporary jar. 2. Put the jar(s) in the UI WEB-INF/lib dir 3. Put this in the grouper UI web.core.xml (or web.xml if not building again), below all of the existing <filter> tags.

Create grouperexternal/public/csrferror.html. Note, would be nice to have this in externalized text... CSRF token is missing, <a href="../../">start over</a> 9. Edit grouperui/apphtml/grouper.html Add this entry under all the existing js files <script src="../../grouperexternal/public/owaspjavascriptservlet"></script> 10. Edit WEB-INF/grouperUi/templates/common/commonTaglib.jsp, add this line <%@ taglib uri="/web-inf/tld/csrfguard.tld" prefix="csrf" %> 11. Edit WEB-INF/grouperUi/templates/simpleMembershipUpdate/simpleMembershipUpdateImport.jsp, add this line below the form tag <input type="hidden" name="<csrf:token-name/>" value="<csrf:token-value uri="/grouper/grouperui/app/simplemembershipupdateimportexport.importcsv"/ >"/> 12. Edit jsp/head.jsp, add this line below the other script tags <script src="grouperexternal/public/owaspjavascriptservlet"></script> 13. Edit WEB-INF/grouperUi2/assetsJsp/commonBottom.jsp, add this below the script tags <script src="../../grouperexternal/public/owaspjavascriptservlet"></script> 14. Edit WEB-INF/grouperUi2/groupImport/groupImport.jsp FROM <form id="importgroupformid" enctype="multipart/form-data" method="post" > TO
<form id="importgroupformid" enctype="multipart/form-data" method="post" > <%-- note this wont work for token per page --%> <input type="hidden" name="<csrf:token-name/>" value="<csrf:token-value />"/> Note, you can test that it works by setting up a static HTML page to remove a member from a group, or you can comment out the JS include in the the head.jsp or other files and try to use the UI, you will get an error
