Severity ?
Summary
The authentication implementation in the web server on Siemens SCALANCE X-200 switches with firmware before 5.0.0 does not use a sufficient source of entropy for generating values of random numbers, which makes it easier for remote attackers to hijack sessions by predicting a value.
