(Sun Issues Fix for Solaris) Tomcat Input Validation Holes in the JSP Examples, Manager, and Host Manager Permit Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1020417
SecurityTracker URL:  http://securitytracker.com/id/1020417
CVE Reference:   CVE-2007-2449, CVE-2007-2450   (Links to External Site)
Date:  Jul 2 2008
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 4.0.0 to 4.0.6, 4.1.0 to 4.1.36, 5.0.0 to 5.0.30, 5.5.0 to 5.5.24, 6.0.0 to 6.0.13
Description:   Two vulnerabilities were reported in Tomcat. A remote user can conduct cross-site scripting attacks.

The JSP examples web application does not properly filter HTML code from user-supplied input before displaying the input. A remote user can create a specially crafted URL that, when loaded by a target user, will cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the Tomcat software and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

A demonstration exploit URL is provided:

http://[target]:[port]/jsp-examples/snp/snoop.jsp;<script>alert()</script>test.jsp

This vulnerability was reported to JPCERT by a researcher.

The Tomcat Manager and Host Manager web applications also do not properly filter HTML code. A remote user can conduct cross-site scripting attacks against authenticated target users.

Daiki Fukumori, Secure Sky Technology, discovered this vulnerability.

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the Tomcat software, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.
Solution:   Sun has issued a fix for Tomcat on Solaris.

SPARC Platform

* Solaris 10 with patch 122911-12 or later

x86 Platform

* Solaris 10 with patch 122912-12 or later
