CVE-2025-10035Known exploitationNetwork attack vectorHinoki check available

Unauthenticated command execution via forged license response

Published Sep 18, 2025 · Updated Sep 18, 2025

Deserialization in Fortra GoAnywhere MFT 7.8.3 and earlier allows remote attackers to execute commands through a forged license response. LicenseResponseServlet passes the response to BundleWorker.verify, which invokes SignedObject.getObject and deserializes its embedded object. The Admin Console must be network-reachable; successful exploitation runs commands in the server process context and enables full host compromise.
