Published Mar 30, 2026 · Updated Mar 30, 2026

Denial of service in SmartFTP Client 9.0.2615.0 allows local users to crash the application via an oversized Host value. The connection dialog accepts a 300-character repeated string in the Host field and crashes when that value is pasted. Access to an interactive Windows session and the client UI is required; the demonstrated consequence is termination of the local client process.
