CVE-2013-5709
First published: Tue Sep 17 2013(Updated: )
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.
