Zero Day Initiative Advisory 10-083 - 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 snmpviewer.exe CGI. The doLoad function in this process calls sprintf() with a %s format specifier and unsanitized user input retrieved from two separate POST variables (act and app). By providing large enough strings a remote attacker can cause a stack-based buffer overflow and eventually execute arbitrary code under the context of the webserver process.
