Description: A vulnerability was reported in the Sun Java System Portal Server in the Calendar Server. A remote authenticated user can gain access to calendar data when proxy authentication is enabled.
Sun reported that a remote authenticated user can gain Calendar Server administrator credentials if the user changes the display
options to select a non-default view. This allows the user to have unrestricted read and write access to the calendar data.
The
system is only affected if Admin Proxy Authentication is configured on the Calendar Server and if Calendar access is provided via
the "Portal" communication channel and not the "Unified Web Client" or the "Calendar Web Client".
|
Impact: A remote authenticated user can gain read and write access to calendar data.
|
Solution: Sun has issued the following fixes:
SPARC Platform
Sun Java System Portal Server Software 6.2 with patch 116856-10 or later
X86
Platform
Sun Java System Portal Server Software 6.2 with patch 117757-09 or later
As a workaround, Sun indicates that you
can prohibit end users from editing the calendar channels "calendar" or "view" display profile properties when Admin Proxy Authentication
is enabled.

57586 Proxy Authentication to Calendar Server Fails if Portal Display Preferences Are
Changed 21 Jul 2004
Sun reported that a remote authenticated user can gain Calendar Server administrator

only if Admin Proxy Authentication is configured on the Calendar Server and if Calendar
access is provided via the "Portal" communication channel and not the "Unified Web Cli
ent"

As a workaround, Sun indicates that you can prohibit end users from editing the calendar
channels "calendar" or "view" display profile properties when Admin Proxy Authent
ication
is enabled.
