Internet Explorer 5.0 records the username and password for FTP servers in the URL history, which could allow (1) local users to read the information from another user's index.dat, or (2) people who are physically observing ("shoulder surfing") another user to read the information from the status bar when the user moves the mouse over a link.

Security readout for executives and security teams

This issue affects Internet Explorer 5.0 handling of FTP links that contain usernames and passwords. The browser could leave those credentials visible in history files or the status bar, creating a credential disclosure risk on shared, legacy, or physically observed machines. Exposure is most likely limited to legacy environments still using Internet Explorer 5.0 with FTP URLs containing credentials, especially shared workstations, kiosks, or systems where user profile files are accessible to others. Treat this as a legacy credential hygiene issue, not a broad internet-facing emergency. Prioritize environments with old browsers, shared desktops, sensitive FTP access, or weak workstation separation. Mitigation focus: Remove or isolate Internet Explorer 5.0 from legacy systems.; Stop embedding FTP usernames and passwords in URLs.; Check vendor or platform guidance for supported history cleanup procedures..
