===================================================================== CERT-Renater Note d'Information No. 2009/VULN071 _____________________________________________________________________ DATE : 27/02/2009 HARDWARE PLATFORM(S) : / OPERATING SYSTEM(S) : Solaris 9, Solaris 10, OpenSolaris running Tomcat 5.5. ====================================================================== http://sunsolve.sun.com/search/printfriendly.do?assetkey=1-66-251986-1 ______________________________________________________________________ Solution Type: Sun Alert Solution 251986 : Security Vulnerabilities in Tomcat 5.5 may Lead to Cross Site Scripting (XSS) or Directory Traversal Bug ID: 6755592 Product Solaris 9 Operating System Solaris 10 Operating System OpenSolaris Date of Resolved Release: 25-Feb-2009 SA Document Body Security vulnerabilities in Tomcat 5.5 may lead to Cross Site Scripting (XSS) or directory traversal: 1. Impact There are three security vulnerabilities in the Tomcat JSP/Servlet container that affect Tomcat 5.5 bundled in Solaris 9 and Solaris 10. The first two security vulnerabilities are Cross Site Scripting (XSS) issues. One in the HttpServletResponse.sendError method (CVE-2008-1232) and the other in the Tomcat Virtual Host Manager (CVE-2008-1947). These may allow a local or remote unprivileged user to inject arbitrary web script or HTML, which in turn may allow the unprivileged user to bypass access control and gain access to unauthorized data. The third security vulnerability is a Directory Traversal vulnerability in the RequestDispatcher class (CVE-2008-2370) that may allow a local or remote unprivileged user to bypass access control and gain access to unauthorized data. Additional information regarding these issues is available at: * CVE-2008-1232 at: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1232 * CVE-2008-1947 at: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1947 * CVE-2008-2370 at: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-2370 2. Contributing Factors These issues can occur in the following releases: SPARC Platform * Solaris 9 without patch 114016-03 * Solaris 10 without patch 122911-15 * OpenSolaris based upon builds snv_01 through snv_100 x86 Platform * Solaris 9 without patch 114017-03 * Solaris 10 without patch 122912-15 * OpenSolaris based upon builds snv_01 through snv_100 Note 1: Solaris 8 does not include support for Tomcat and therefore is not impacted by these issues. Note 2: OpenSolaris distributions may include additional bug fixes above and beyond the build from which it was derived. To determine the base build of OpenSolaris, the following command can be used: $ uname -v snv_86 Note 3: A system is only vulnerable to this issues if Tomcat 5.5 has been configured and is running on the system. To determine if Tomcat is installed on the system, a command such as the following can be used: % pkginfo SUNWtcatr system SUNWtcatr Tomcat Servlet/JSP Container (root) Tomcat can be configured to start in various different ways. For assistance in determining if Tomcat is configured to run on the system, consult the documentation which is usually available in the "/var/apache/tomcat/webapps/tomcat-docs" directory. 3. Symptoms There are no predictable symptoms that would indicate the described issues have been exploited. 4. Workaround There are no workarounds for these issues. Please see the Resolution section below. 5. Resolution These issues are resolved in the following releases: SPARC Platform * Solaris 9 with patch 114016-03 or later * Solaris 10 with patch 122911-15 or later * OpenSolaris based upon builds snv_101 or later x86 Platform * Solaris 9 with patch 114017-03 or later * Solaris 10 with patch 122912-15 or later * OpenSolaris based upon builds snv_101 or later For more information on Security Sun Alerts, see Technical Instruction ID 213557.
