Vulnerability Details

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Hewlett-Packard OpenView Network Node Manager. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the ovwebsnmpsrv.exe application which is launched when a request is received for the jovgraph.exe CGI application. This process copies the contents of the 'sel' POST variable a user-controllable amount of times into a static stack buffer. By repeating a specific string as the contents of the 'arg' POST variable this buffer can be overflowed leading to arbitrary code execution.

Vendor Response

Hewlett-Packard has issued an update to correct this vulnerability. More details can be found at:
