DESCRIPTION:
Multiple vulnerabilities have been reported in Schneider Electric
Modicon Quantum Series Modules, which can be exploited by malicious
people to conduct cross-site scripting attacks and cause a DoS
(Denial of Service).

1) Certain unspecified input is not properly sanitised before being
returned to the user. This can be exploited to execute arbitrary HTML
and script code in a user's browser session in context of an affected
site.

2) An unspecified error within the HTTP server can be exploited to
cause a buffer overflow and crash the device.

3) An unspecified error within the FTP server can be exploited to
cause a buffer overflow and crash the device.

SOLUTION:
Filter malicious characters and character sequences in a proxy.
Restrict access to trusted hosts only.
