  NetOp School Admin Vulnerability (Authorization Bypass)
------------------------------------------------------------------------

SUMMARY

Feature-rich <http://www.crossteccorp.com/netopschool/index.html> NetOp
School puts teachers and corporate trainers center stage in networked
classrooms or Internet-based virtual classrooms. A security vulnerability
in the product allows local unprivileged users to gain administrative
access of the NetOp product.

DETAILS

Vulnerable systems:
NetOp School version 1.5

By default when a user logs into a workstation the student version of
NetOp is run. If a user (student) attempts to execute the admin version of
NetOp then the required password dialog will appear and the user will need
to know that password if they wish to run the program. The flaw is in the
way the program reacts when the student version is not running. For
example, a student can use any type of task manager to kill the student
version and when he or she goes to open the admin version all security
checks and password dialogs are bypassed.

This gives the student or non-authorized user full access to any
workstation logged in to the network. It also allows users to "spy" on
anybody in the network.
