-- CVE ID:
CVE-2011-1850

-- CVSS:
10, (AV:N/AC:L/Au:N/C:C/I:C/A:C)

-- Affected Vendors:
Hewlett-Packard

-- Affected Products:
Hewlett-Packard H3C Intelligent Management Center

-- TippingPoint(TM) IPS Customer Protection:
TippingPoint IPS customers have been protected against this
vulnerability by Digital Vaccine protection filter ID 10910.

-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of HP 3com/H3C Intelligent Management Center.
Authentication is not required to exploit this vulnerability. 

The flaw exists within the dbman.exe component which listens by default
on UDP port 2810. When logging received actions to dbman_debug.log
sprintf is used to build the log message. The process does not properly
verify the destination buffer on the stack is of sufficient size to
handle the newly created string. A remote attacker can exploit this
vulnerability to execute arbitrary code under the context of the SYSTEM
user.

-- Vendor Response:
Hewlett-Packard has issued an update to correct this vulnerability. More
