CPE, which stands for Common Platform Enumeration, is a standardized scheme for naming hardware, software, and operating systems. CPE provides a structured naming scheme to uniquely identify and classify information technology systems, platforms, and packages based on certain attributes such as vendor, product name, version, update, edition, and language.
CWE, or Common Weakness Enumeration, is a comprehensive list and categorization of software weaknesses and vulnerabilities. It serves as a common language for describing software security weaknesses in architecture, design, code, or implementation that can lead to vulnerabilities.
CAPEC, which stands for Common Attack Pattern Enumeration and Classification, is a comprehensive, publicly available resource that documents common patterns of attack employed by adversaries in cyber attacks. This knowledge base aims to understand and articulate common vulnerabilities and the methods attackers use to exploit them.

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.

# Xchat <= 2.8.7b Remote Code Execution (tested on Windows XP SP1+SP2+SP3, IE6 & IE7 fully patched)
# Vendor : http://xchat.org/
# Affected Os : Windows *
# Risk : critical
#
# This bug is related to the URI Handler vulnerability but the approch is a bit different.
# We don't use any % or ../../../ as the others related bugs, just a single "
# According to the registry , when the IRCS:// URI is called , the command launched is :
# C:\Program Files\xchat\xchat.exe --existing --url="%1"
#
# The xchat --help option tells us :
# " --command=COMMAND :Send a command to existing xchat "
#
# So we add a simple " at the end of the URL and we're in business ?
# Yep =) ircs://blabla@3.3.3.3" --command "shell calc"
#
# Note: The victim needs to be connected to an irc server , and also need IE * .
