Unauthenticated service crash via malformed Host header

Published Jan 7, 2020 · Updated Aug 6, 2024

Denial of service in AultWare pwStore 2010.8.30.0 allows remote attackers to crash its web service with a malformed HTTP request. The request parser passes a malformed Host header to C70RUN!memcpy with a null destination, triggering an access violation. No authentication or user interaction is required; the demonstrated consequence is termination of the pwStore web service on Windows.
