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.

Utempter allows device names that contain .. (dot dot) directory traversal sequences, which allows local users to overwrite arbitrary files via a symlink attack on device names in combination with an application that trusts the utmp or wtmp files.

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 utempter is affected by multiple local vulnerabilities. The first issue is due to an input validation error that causes the application to exit improperly; facilitating symbolic link attacks. The second issue is due to a failure of the application to properly validate buffer boundaries.
The first issue results in a symbolic link vulnerability. Since utempter runs with root privileges, this issue could be leveraged to corrupt arbitrary, attacker-specified system files.
The second problem presents itself when utempter processes certain strings. These errors may cause the affected process to crash. It has been conjectured that this may be leveraged to execute arbitrary code on the affected system, however this is currently unverified.
An attacker would create the following symbolic link that references an arbitrary system file:
/tmp/tty0
The attacker would then provide the following device descriptor string to the application:
/dev/../tmp/tty0
