User redirection via unvalidated nextPage destination

Published Jul 14, 2025 · Updated Jul 15, 2025

Open redirect in WeGIA before 3.4.5 allows remote attackers to redirect users to arbitrary sites through a crafted application URL. The control.php endpoint uses the unvalidated nextPage query parameter as the redirect destination, accepting absolute external URLs. Exploitation requires a user to follow the crafted link, enabling phishing or credential harvesting under the trusted application domain.
