CVE-2022-43847Network attack vector

Response manipulation via unvalidated Host header

Published Apr 14, 2025 · Updated Aug 15, 2025

HTTP header injection in IBM Aspera Console 3.4.0 through 3.4.4 allows remote authenticated users to manipulate responses via the Host header. The application fails to validate attacker-controlled Host header input before using it to produce HTTP headers, enabling cross-site scripting and cache poisoning. Low-privileged network access is required, and successful exploitation can hijack sessions or alter cached responses without interrupting service.
