CVE-2013-5709
Last modified
CVE-2013-5709 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 2.99% chance of exploitation in the next 30 days.
