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:
</p><p>
<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>
</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=117757&rev=09">117757-09</a>
</li>
</ul><p>
The described issue only occurs if the following conditions are true:
</p><ul>
<li>
Admin Proxy Authentication is configured on the Calendar Server
</li>
<li>
Calendar access is via the "Portal" communication channel and not the
"Unified Web Client" or the "Calendar Web Client" </li>
</ul><p>
<b>Note:</b> This issue only affects the calendar component. The calendar configuration information is not affected.
</p><h2>
3. Symptoms
</h2><p>
There are no reliable symptoms that would indicate the described issue
has been exploited to gain access to calendar data. </p></font><table width="100%" cellpadding="2" cellspacing="0" border="0"><tbody><tr bgcolor="#999999">

<td align="right"><b><a href="#top"><font size="2" color="#ffffff">Top</font></a></b></td></tr></tbody></table>
<font size="2"><h2>
4. Relief/Workaround
