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.

The ftp daemon derived from 4.x BSD source contains a serious vulnerability that may compromise root access.
There exists a one byte overflow in the replydirname() function. The overflow condition is due to an off-by-one bug that allows an attacker to write a null byte beyond the boundaries of a local buffer and over the lowest byte of the saved base pointer.
As a result, the numerical value of the pointer decreases (and it thus points to a higher location (or lower address) on the stack than it should) and when the replydirname() function returns, the modified saved base pointer is stored in the base pointer register. When the calling function returns, the return address is read from an offset of where the base pointer points to. With the last byte of the base pointer zero, this will be a location other than where it should be.
If this region of the stack is under the control of the attacker, such as the local variable which contained the extra byte in the first place, an arbitrary address can be placed there that will be used as the saved return address by the function.
This is the case in ftpd. It is possible for an attacker to force the ftp daemon to look in user-supplied data for a return address and then execute instructions at the location as root.
This vulnerability can be exploited on systems supporting anonymous ftp if a writeable directory exists (such as an "incoming" directory). This is rarely in place by default.
It should noted that OpenBSD ships with ftp disabled, though it is an extremely commonly used service.
