Technical details
The vulnerability stems from an overly permissive Cross-Origin Resource Sharing (CORS) or similar cross-domain policy in Armoury Crate's local service endpoint. An attacker can craft a web page that, when visited by a user, sends a UNC path request (e.g., \\attacker\share) to the application's local service. This triggers NTLM authentication, causing the user's browser to send the user's NTLM hash to the attacker-controlled server. No authentication or special privileges are required from the victim's perspective—only clicking a link or visiting a page. The attack vector is network-based but requires user interaction (visiting a crafted webpage).
