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.
The SNMPv3 functionality on Siemens Scalance X200 IRT switches with firmware before X-200IRT 5.1.0 does not properly validate credentials, which allows remote attackers to execute arbitrary SNMP commands by leveraging knowledge of a username.
The web interface on Siemens Scalance X200 IRT switches with firmware before X-200IRT 5.1.0 relies on client-side privilege checks, which allows remote authenticated users to execute arbitrary commands via unspecified vectors.
