CVE-2024-30133

Local data compromise via incorrect control flow

Published Nov 12, 2024 · Updated Nov 12, 2024

Always-incorrect control flow in HCL Traveler for Microsoft Outlook before 3.0.11 allows local users to read or alter data and interrupt service. HCL states only that the application insufficiently manages execution flow, allowing unexpected modification; it does not identify the affected file, function, input, or incorrect operation. A low-privileged local account is required, no user interaction is reported, and the bounded consequences are data exposure, data alteration, and service interruption.
