-- Vulnerability Details:
These vulnerabilities allow remote attackers to execute arbitrary code
on vulnerable installations of Hewlett-Packard (HP) OpenView Network
Node Manager (NNM). Authentication is not required to exploit these
vulnerabilities.

The specific flaws exists within the CGI applications that handle the
management of the NNM server. Due to lack of bounds checking during a
call to sprintf(), sending overly long arguments to the various CGI
variables result in a classic stack overflow leading to compromise of
the remote server. Exploitation leads to code execution running under
the credentials of the web server. Further techniques can be leveraged
to gain full SYSTEM access.

The following is a list of vulnerable CGI applications:

- ovlogin.exe
- OpenView5.exe
- snmpviewer.exe
- webappmon.exe


-- Vendor Response:
Hewlett-Packard has issued an update to correct this vulnerability. More
details can be found in HP Security Bulletin Document ID c01188923.
