CVE-2013-4651: Siemens Scalance w700 Series Firmware

Medium severity, CVSS 6.6. EPSS: 1% chance of exploitation in the next 30 days.

Siemens Scalance W7xx devices with firmware before 4.5.4 use the same hardcoded X.509 certificate across different customers' installations, which makes it easier for remote attackers to conduct man-in-the-middle attacks against SSL sessions by leveraging the certificate's trust relationship.
