Vulnerability DetailsThis 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 ovlogin.exe CGI application. During authentication both the userid and passwd POST variables are passed to this CGI and copied in to a static 0x100 byte heap buffer via a sprintf() call. By specifying large enough strings this buffer can be overflowed leading to arbitrary code execution.
