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.

Security readout for executives and security teams

CVE-2013-5709 affects the web server authentication on Siemens SCALANCE X-200 switches running firmware before 5.0.0. The device used weak randomness for session-related values, making session hijacking easier for a remote attacker who can reach the web interface. Exposure is most likely where Siemens SCALANCE X-200 switch web management interfaces are reachable by users or networks beyond tightly controlled administration segments, especially on firmware earlier than 5.0.0. Treat this as a targeted operational technology exposure issue. Prioritize internet- or broadly reachable management interfaces first, then schedule firmware remediation for remaining SCALANCE X-200 assets through normal change control. Mitigation focus: Upgrade Siemens SCALANCE X-200 firmware to 5.0.0 or later where applicable.; Review Siemens ProductCERT advisory SSA-850708 for current vendor guidance.; Restrict web management access to trusted administration networks only..
