A vulnerability in Internet Explorer 4.01 allows remote attackers to read arbitrary local files and spoof web pages by crafting a malicious 'about:' Javascript URL containing a '%01' character. This character manipulation causes Internet Explorer to treat the domain specified after '%01' as trusted, bypassing normal security restrictions and enabling unauthorized access to local resources or deceptive content rendering.
