Sun(sm) Alert Notification
     * Sun Alert ID: 102958
     * Synopsis: Cross-site Scripting Vulnerability (XSS) Affecting Pages
       Generated with JavaDoc Tool
     * Category: Security
     * Product: Java 2 Platform, Standard Edition
     * BugIDs: 6490790
     * Avoidance: Upgrade
     * State: Resolved
     * Date Released: 28-Jun-2007
     * Date Closed: 28-Jun-2007
     * Date Modified:

1. Impact

   A defect in the Javadoc tool in various releases of the JDK may lead
   to the generation of HTML documentation pages which contain a
   potential cross-site scripting (XSS) vulnerability. This may allow a
   remote user to gain access to cookies from the website that hosts the
   generated documentation.

   Sun acknowledges, with thanks, Martin Straka, for bringing this issue
   to our attention.

2. Contributing Factors

   This issue can occur in the following releases for all platforms
   (Solaris, Linux, and Windows):
     * JDK 6
     * JDK 5.0 Update 11 and earlier

   Note: The Javadoc tool included in SDK 1.4.x and earlier is not
   affected by this issue.

   To determine the version of Java on a system, the following command
   can be run:
    % java -version
    java version "1.5.0_02-b09"

   For this vulnerability to be exploited, a user must click a link
   (created by a malicious user) in a website or email that points to a
   vulnerable "index.html" documentation page. The user's cookies from
   the website that hosts the "index.html" documentation page may then be
   accessed by the malicious user.

3. Symptoms

   There are no predictable symptoms that would indicate the described
   issue has been exploited.

4. Relief/Workaround

   Please see the "Note" in the Resolution section below.

5. Resolution

   This issue is addressed in the following releases for all platforms
   (Solaris, Linux, and Windows):
     * JDK 6 Update 1 or later
     * JDK 5.0 Update 12 or later

   JDK 6 is available for download at the following link:

   http://java.sun.com/javase/downloads/index.jsp

   JDK 5.0 is available for download at the following link:

   http://java.sun.com/javase/downloads/index_jdk5.jsp

   Note: In order to fully resolve this issue, any "index.html" page that
   was generated with an affected version of the Javadoc tool must be
   regenerated using a Javadoc tool in one of the releases mentioned in
   this resolution section.
