Sun Security Advisory - A security vulnerability in Sun Java System Portal Server Software 6.2 may allow a user to gain Calendar Server administrator credentials if the user changes the display options to select a non-default view. With these credentials, a user's session has unrestricted access to the calendar data and hence manipulation of that data. Such manipulation could include, but is not limited to: the deletion, creation, and modification of users, user information, calendar entries, and historical data.

1. Impact
</h2><p>
A security vulnerability in Sun Java System Portal Server Software 6.2
may allow a user to gain Calendar Server administrator credentials if
the user changes the display options to select a non-default view. With
these credentials, a user's session has unrestricted access to the
calendar data and hence manipulation of that data. Such manipulation
could include, but is not limited to: the deletion, creation, and
modification of users, user information, calendar entries, and
historical data. </p><h2>
2. Contributing Factors
</h2><p>
This issue can occur in the following releases:

<b>SPARC Platform</b>
</p><ul>
<li>
Sun Java System Portal Server Software 6.2 (for Solaris 8 and Solaris 9) without patch <a href="http://sunsolve.sun.com/pub-cgi/findPatch.pl?patchId=116856&rev=10">116856-10</a>
</li>
</ul><p>
<b>X86 Platform</b>
