DESCRIPTION:
Ruben Santamarta has reported some security issues in multiple
Schneider Electric modules, which can be exploited by malicious
people to bypass certain security restrictions.

1) The Telnet service contains undocumented hardcoded credentials,
which can be exploited to gain access to the service and e.g. modify
module's memory and execute arbitrary code.

2) The Windriver Debug service contains undocumented hardcoded
credentials, which can be exploited to gain access to the service and
e.g. modify module's memory and execute arbitrary code.

3) The FTP service contains undocumented hardcoded credentials, which
can be exploited to gain access to the service and e.g. modify HTTP
passwords and upload malicious firmware.

Please see the ICS-CERT's advisory for a list of affected products
and versions.

SOLUTION:
Restrict access to trusted hosts only.
