Novell eDirectory NDS Server Buffer Overflow
------------------------------------------------------------------------
SUMMARY
<http://www.novell.com/products/edirectory/> Novell eDirectory (formerly
called Novell Directory Services) is an X.500 compatible directory service
software product released in 1993 by Novell, Inc. for centrally managing
access to resources on multiple servers and computers within a given
network.
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Novell eDirectory. Exploitation does not
require authentication.
DETAILS
Vulnerable Systems:
* Novell eDirectory version 8.8
* Novell iMonitor version 2.4
The specific flaw exists within the iMonitor NDS Server, which by default
exposes an HTTP interface on TCP port 8028 and an HTTPS interface on TCP
port 8030. During the parsing of long URIs to the 'nds' path a trivially
exploitable stack-based buffer overflow occurs.
Vendor Response:
Novell has addressed this issue in the latest version of eDirectory
iMonitor.
