For further product information on the TippingPoint IPS, visit: http://www.tippingpoint.com -- 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 OvWebHelp.exe CGI application. During a string concatenation the process takes the value of the Topic POST variable and copies it without any length checks into a static 0x400 byte heap buffer. By providing a large enough string this buffer can be overrun leading to arbitrary code execution. -- Vendor Response: Hewlett-Packard has issued an update to correct this vulnerability.
