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. More details can be found at:
