(0Day) HP Diagnostics Server magentservice.exe Remote Code Execution 
Vulnerability

ZDI-12-162: August 22nd, 2012

CVSS Score

Affected Vendors

Vulnerability Details

This vulnerability allows remote attackers to execute arbitrary code on 
vulnerable installations of HP Diagnostics Server. Authentication is not 
required to exploit this vulnerability.

The specific flaw exists within the magentservice.exe process which listens 
on port 23472 by default. The process performs insufficient bounds checking 
on user-supplied data prior to copying it into a fixed-length buffer on the 
stack. Remote, unauthenticated attackers can exploit this vulnerability by 
sending malformed message packets to the target, which could ultimately lead 
to arbitrary code execution under the context of the SYSTEM user.

Vendor Response
Hewlett-Packard states:

This vulnerability is being disclosed publicly without a patch in accordance 
with the ZDI 180 day deadline.
