DESCRIPTION:
A vulnerability has been reported in NetSupport Manager, which can be
exploited by malicious people to disclose potentially sensitive
information.

The vulnerability is caused due to an error in the HTTP protocol
implementation, which does not encrypt the headers of some of the
NetSupport HTTP packets. This can be exploited to disclose certain
sensitive information e.g. client IP address, MAC address, and
username of the logged in user by intercepting the HTTP packets
between the NetSupport Manager Gateway and NetSupport Manager
Controls or NetSupport Manager Clients.

The vulnerability is reported in version NSM 11.00.

SOLUTION:
Update to version 11.00.0005 or later.

PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
