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.

This process copies the Host header from HTTP requests into a fixed-length buffer located in the .DATA section via a call to strcat(). By specifying a string length within a certain range this buffer can be overflowed leading to arbitrary code execution.
