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.

Buffer overflow in the lprm command in the lprold lpr package on SuSE 7.1 through 7.3, OpenBSD 3.2 and earlier, and possibly other operating systems, allows local users to gain root privileges via long command line arguments such as (1) request ID or (2) user name.

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.

It has been reported that a vulnerability in the handling of some types of requests exists in lprm. When an attacker sends a maliciously crafted string to a configured printer through the lprm command, it may be possible to execute code.

lprm-bsd.c - Exploit for lprm vulnerability in
OpenBSD and FreeBSD-stable
k0ded by Niall Smart, njs3@doc.ic.ac.uk, 1998.
The original version of this file contains a blatant error
which anyone who is capable of understanding C will be able
to locate and remove. Please do not distribute this file
without this idiot-avoidance measure.
Typical egg on FreeBSD: 0xEFBFCFDF
Typical egg on OpenBSD: 0xEFBFD648
The exploit might take a while to drop you to a root shell
depending on the timeout ("tm" capability) specified in the
printcap file.
