CVE-2014-3753

Master Password capture via cross-desktop keylogging

Published Jan 9, 2020 · Updated Aug 6, 2024

Information disclosure in AgileBits 1Password 1 for Windows 1.0.9.340 and earlier allows local users to capture the Master Password. Secure Desktop fails to reject an unexpected process that watches for newly created Windows desktops and launches a keylogger inside each one. Exploitation requires same-user malware and user interaction with Secure Desktop; the resulting disclosure is limited to keystrokes entered during unlocking.
