ZDI-06-016: Novell eDirectory 8.8 NDS Server Buffer Overflow Vulnerability
http://www.zerodayinitiative.com/advisories/ZDI-06-016.html
May 22, 2006

-- CVE ID:
CVE-2006-2496

-- Affected Vendor:
Novell

-- Affected Products:
Novell eDirectory 8.8
Novell iMonitor 2.4

-- TippingPoint(TM) IPS Customer Protection:
TippingPoint IPS customers have been protected against this
vulnerability since March 14, 2006 by Digital Vaccine protection
filter ID 4188. For further product information on the TippingPoint IPS:

    http://www.tippingpoint.com 

-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Novell eDirectory. Exploitation does not
require authentication.

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. More information is available from:

http://support.novell.com/cgi-bin/search/searchtid.cgi?/2973759.htm

-- Disclosure Timeline:
2006.03.14 - Digital Vaccine released to TippingPoint customers
2006.03.20 - Vulnerability reported to vendor
2006.05.22 - Coordinated public release of advisory

-- Credit:
This vulnerability was discovered by CIRT.DK.

-- About the Zero Day Initiative (ZDI):
Established by TippingPoint, a division of 3Com, The Zero Day Initiative
