AusCERT recommends that network administrators restrict access to vulnerable systems in line with security best practice, including implementation of appropriate firewall rules. - --------------------------BEGIN INCLUDED TEXT-------------------- (0Day) HP Diagnostics Server magentservice.exe Remote Code Execution Vulnerability ZDI-12-162: August 22nd, 2012 CVSS Score 10, (AV:N/AC:L/Au:N/C:C/I:C/A:C) Affected Vendors Hewlett-Packard Affected Products Diagnostics Server 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.
