-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of HP Network Node Manager. Authentication is
not required to exploit this vulnerability.

The specific flaw exists within the Network Monitor (netmon.exe) daemon.
This process can be started by invoking the webappmon.exe CGI
application through the webserver. When the _OVParseLLA function defined
within ov.dll is called from netmon.exe it directly copies the value of
the 'sel' POST variable into a fixed-length stack buffer with a call to
strcpy(). This can be leveraged by remote attackers to execute arbitrary
code under the context of the webserver process.


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