DESCRIPTION:
A vulnerability has been discovered in ScadaTec ModbusTagServer and
ScadaTec ScadaPhone, which can be exploited by malicious people to
compromise a user's system.

The vulnerability is caused due to a boundary error when importing an
archived project and can be exploited to cause a stack-based buffer
overflow via a specially crafted ZIP file.

Successful exploitation allows execution of arbitrary code, but
requires tricking a user into importing a malicious project file.

The vulnerability is confirmed in the following products (other
versions may also be affected):
* ScadaTec ModbusTagServer version 4.1.1.81.
* ScadaTec ScadaPhone version 5.3.11.1230.

SOLUTION:
Do not import project files from untrusted sources.
