"A vulnerability has been identified in LOGO! 8 BM (incl. SIPLUS
variants) (All versions). Affected devices do not properly validate an
offset value which can be defined in TCP packets when calling a
method. This could allow an attacker to retrieve parts of the content
of the memory.

This plugin only works with Tenable.ot.

Siemens is preparing updates and recommends specific countermeasures for products where updates are not yet available:

- Only for versions prior to V8.3: Restrict access to port 10005/TCP to only trusted IP addresses.
- Only for versions including and since V8.3: Restrict access to port 8443/TCP to only trusted IP addresses.
- Restrict access to port 135/TCP to trusted IP addresses only.

As a general security measure, Siemens strongly recommends protecting network access to devices with appropriate
mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends configuring the
environment according to Siemens' operational guidelines for industrial security and following the recommendations in
the product manuals.

Siemens has provided additional information on industrial security.
