HP Network Node Manager (NNM) is an application suite that is used to map out and manage network topography. NNM runs on a variety of platforms, including Linux and multiple versions of Windows. For more information, see the vendor's site at the following link.
Remote exploitation of a stack based buffer overflow vulnerability in Hewlett-Packard Development Co. LP (HP)'s Network Node Manager could allow an attacker to execute arbitrary code with the privileges of the affected service.
The vulnerability exists within the 'rping' application, which is distributed with the Linux version of NNM. It is possible for a remote attacker to launch the 'rping' application and trigger a stack based buffer overflow.
Exploitation of this vulnerability results in the execution of arbitrary code with the privileges of the affected service. On RedHat Enterprise 4, the application is started as the user 'bin'. 'rping' is not compiled with compiler protections such as stack cookies or the -pie flag, which makes exploitation less difficult.
iDefense has confirmed the existence of this vulnerability in Network Node Manager version 7.53 for Linux. Previous versions may also be affected. The Windows version is not affected.
By default, the webappmon.exe CGI application does not require a user to be authenticated. By changing the session.conf file and setting UserLogin to ON, it is possible to require valid credentials in order to run. The 'ovhtpasswd' application can then be used to add valid credentials.
