NTLM hash disclosure via pre-validation path resolution
Published Aug 12, 2024 · Updated Aug 12, 2024
Path traversal in Snowflake Streamlit before 1.37.0 allows remote authenticated users to disclose the Windows service account's NTLM hash. AppStaticFileHandler.validate_absolute_path resolves and inspects a requested path before Tornado confirms that it remains under the static root. A hosted Windows app must enable static file sharing; a crafted path can expose the authentication material for the account running Streamlit.
