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.
BSD/OS 2.1,Caldera Network Desktop 1.0,Eric Allman Sendmail <= 8.8.2,FreeBSD 2.1.5/2.1.6,HP-UX <= 10.20,AIX 4.2,RedHat 4.0 Sendmail Daemon Mode Vulnerability
source: https://www.securityfocus.com/bid/716/info
Sendmail is often run in daemon mode so that it can "listen" for incoming mail connections on the standard SMTP networking port, usually port 25. The root user is the only user allowed to start sendmail this way, and sendmail contains code intended to enforce this restriction.
Unfortunately, due to a coding error, sendmail can be invoked in daemon mode in a way that bypasses the built-in check. When the check is bypassed, any local user is able to start sendmail in daemon mode. In addition, as of version 8.7, sendmail will restart itself when it receives a SIGHUP signal. It does this restarting operation by re-executing itself using the exec(2) system call. Re-executing is done as the root user. By manipulating the sendmail environment, the user can then have sendmail execute an arbitrary program with root privileges.

# Hi !
# This is exploit for sendmail smtpd bug
# (ver. 8.7-8.8.2 for FreeBSD, Linux and may be other platforms).
# This shell script does a root shell in /tmp directory.
# If you have any problems with it, drop me a letter.
# Have fun !
