Source: http://www.digitalstrom.com/en/idea/Good-morning/ Business recommendation: ------------------------ SEC Consult recommends every user to sign out immediately after configuring the Digitalstrom installation in the Digitalstrom Konfigurator. This should prevent cross-site request forgery attacks. Furthermore every user should be aware that an attack could occure everytime when he clicks on an unknown link. However, SEC Consult recommends the vendor to conduct a comprehensive security analysis, based on security source code reviews, in order to identify all available vulnerabilities in the Digitalstrom Konfigurator and increase the security of its customers. Vulnerability overview/description: ----------------------------------- 1) Multiple Persistent Cross-Site Scripting Digitalstrom Konfigurator suffers from multiple cross-site scripting vulnerabilities, which allow stealing session tokens and impersonation of other users in order to gain unauthorized access to the web interface. Furthermore it is possible to alter the contents of the interface in the context of the current user. 2) Cross-Site Request Forgery Digitalstrom Konfigurator doesn't implement any kind of cross-site request forgery protection.

For example, an administrator can be forced to execute unwanted actions. Some of these actions are: -) Change network configuration -) Enable SSH service -) Turn various devices on and off Proof of concept: ----------------- Has been removed due to the request from the vendor.
