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.

patchadd is the patch management tool included with the Solaris Operating Environment, distributed by Sun Microsystems. A problem exists which could allow a user to corrupt or append system files.
The problem exists in the creation of /tmp files by patchadd. patchadd creates a variety of files in /tmp while installing the patches on the operating system. The files created in /tmp are mode 0666, and are created with the extension sh<pid of patchadd>.1, sh<pid of patchadd>.2, and so on. Running the program requires administrative access. It is possible to brute force guess the pid of patchadd, and create files in the /tmp directory that are symbolic links to sensitive system files.
It is therefore possible for a user with malicious intent to gain elevated privileges, corrupt system files, or execute arbitrary commands.
