CVE-2019-25349Public exploit

Application crash via oversized Servername input

Published Feb 18, 2026 · Updated Feb 18, 2026

Classic buffer overflow in FlowChief scadaApp for iOS 1.1.4.0 allows attackers to crash the application through the Servername field. The login workflow copies a 257-character Servername value without checking that it fits the destination buffer, terminating the app. Exploitation requires local interaction with an iOS device to paste the value and submit the login form; the demonstrated consequence is an application crash only.
