WIT SynApps Runtime through 1.4.11 contains a browser-mediated cross-origin request forgery vulnerability that allows attackers to supply an arbitrary target address during controller onboarding, causing the victim's browser to issue discovery requests to attacker-specified hosts at paths such as /easy/GUI/Skins/Default/SiteLogo and /easy/GUI/Skins/Default/Identity. Attackers can leverage the victim's browser reachability to probe loopback addresses, local hostnames, or internal-only network hosts and initiate the enrollment flow against REDY instances, crossing IT/OT segmentation boundaries through a sanctioned application path.
