Cross-site scripting (XSS) vulnerability in jsp/cal/cal2.jsp in the calendar application in the examples web application in Apache Tomcat on Red Hat Enterprise Linux 5, Desktop Workstation 5, and Linux Desktop 5 allows remote attackers to inject arbitrary web script or HTML via the time parameter, related to "invalid HTML." NOTE: this is due to a missing fix for CVE-2009-0781.

From Red Hat Security Advisory 2010:0580 :

Updated tomcat5 packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies.

A flaw was found in the way Tomcat handled the Transfer-Encoding header in HTTP requests. A specially crafted HTTP request could prevent Tomcat from sending replies, or cause Tomcat to return truncated replies, or replies containing data related to the requests of other users, for all subsequent HTTP requests. (CVE-2010-2227)

The Tomcat security update RHSA-2009:1164 did not, unlike the erratum text stated, provide a fix for CVE-2009-0781, a cross-site scripting (XSS) flaw in the examples calendar application. With some web browsers, remote attackers could use this flaw to inject arbitrary web script or HTML via the 'time' parameter. (CVE-2009-2696)

Two directory traversal flaws were found in the Tomcat deployment process. A specially crafted WAR file could, when deployed, cause a file to be created outside of the web root into any directory writable by the Tomcat user, or could lead to the deletion of files in the Tomcat host's work directory. (CVE-2009-2693, CVE-2009-2902)

Users of Tomcat should upgrade to these updated packages, which contain backported patches to resolve these issues. Tomcat must be restarted for this update to take effect.

From Red Hat Security Advisory 2009:1164 :

Updated tomcat packages that fix several security issues are now available for Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the Red Hat Security Response Team.

Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies.

It was discovered that the Red Hat Security Advisory RHSA-2007:0871 did not address all possible flaws in the way Tomcat handles certain characters and character sequences in cookie values. A remote attacker could use this flaw to obtain sensitive information, such as session IDs, and then use this information for session hijacking attacks.
(CVE-2007-5333)

Note: The fix for the CVE-2007-5333 flaw changes the default cookie processing behavior: with this update, version 0 cookies that contain values that must be quoted to be valid are automatically changed to version 1 cookies. To reactivate the previous, but insecure behavior, add the following entry to the '/etc/tomcat5/catalina.properties' file :

org.apache.tomcat.util.http.ServerCookie.VERSION_SWITCH=false

It was discovered that request dispatchers did not properly normalize user requests that have trailing query strings, allowing remote attackers to send specially crafted requests that would cause an information leak. (CVE-2008-5515)

A flaw was found in the way the Tomcat AJP (Apache JServ Protocol) connector processes AJP connections. An attacker could use this flaw to send specially crafted requests that would cause a temporary denial of service. (CVE-2009-0033)

It was discovered that the error checking methods of certain authentication classes did not have sufficient error checking, allowing remote attackers to enumerate (via brute-force methods) usernames registered with applications running on Tomcat when FORM-based authentication was used. (CVE-2009-0580)

A cross-site scripting (XSS) flaw was found in the examples calendar application. With some web browsers, remote attackers could use this flaw to inject arbitrary web script or HTML via the 'time' parameter.
(CVE-2009-0781)

It was discovered that web applications containing their own XML parsers could replace the XML parser Tomcat uses to parse configuration files. A malicious web application running on a Tomcat instance could read or, potentially, modify the configuration and XML-based data of other web applications deployed on the same Tomcat instance. (CVE-2009-0783)

Users of Tomcat should upgrade to these updated packages, which contain backported patches to resolve these issues. Tomcat must be restarted for this update to take effect.
