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 img.exe component which listens by default on TCP 
port 8800. When handling the a packet type the process uses a user provided 
length value in an arithmetic operation resulting in integer wrapping. The 
process then copies user supplied data into a fixed-length buffer on the heap. 
A remote attacker can exploit this vulnerability to execute arbitrary code 
under the context of the SYSTEM user.

Vendor Response

Hewlett-Packard states:

[May 31, 2011] - This vulnerability is being disclosed publicly
without a patch in accordance with the ZDI 180 day deadline.

- -- Mitigation:
As the affected component is the 'core' process for IMC, we recommend either 
disabling this service entirely until a vendor patch is available or denying 
incoming connections to 8800/tcp, this is the remote vector into the 
vulnerable code.
