Summary
SIMATIC S7-200 SMART devices contain an information disclosure vulnerability which leaves the system susceptible to a family of attacks which rely on the use of predictable IP ID sequence numbers as their base method of attack and eventually could allow an attacker to create a denial of service condition.
Siemens recommends specific countermeasures for products where fixes are not, or not yet available.
