Description

A vulnerability has been identified in SCALANCE M875 (All versions). The web interface on port 443/tcp could allow a Cross-Site Request Forgery (CSRF) attack if an unsuspecting user is tricked into accessing a malicious link. Successful exploitation requires user interaction by an legitimate user, who must be authenticated to the web interface as administrative user.
