Description:   A vulnerability was reported in NetScreen-Security Manager when communicating with ScreenOS 5.0 devices. The default configuration uses clear text communications.

It is reported that the default configuration does not automatically enable encryption of communications between NetScreen appliances and systems that are running ScreenOS 5.0 and the Device Server component of the NetScreen-Security Manager application.

A user monitoring the communications can reportedly intercept configuration data and other information.

Impact:   A remote user monitoring the network between the NetScreen-Security Manager and managed ScreenOS 5.0 devices can obtain configuration data and other information.
Solution:   NetScreen reports that you can use either of the following options to enable 128-bit AES encryption between the NetScreen-Security Manager and devices running ScreenOS 5.0 [quoted]:

"(1) Add the following line in the devSvr.cfg file located in the /usr/netscreen/DevSvr/var/ folder, then restart DevSvr services:

devSvrManager.cryptoKeyLength 128

(2) As root, run the script '', which is available on the NetScreen-Security Manager downloads page at, then restart DevSvr services."

The vendor reports that NetScreen-Security Manager 2004 Feature Pack 1 will include a fix.
