Study Notes
What is a CVE?
- A CVE (Common Vulnerabilities and Exposures) is a unique identifier assigned to a security vulnerability in a software or firmware.
- CVEs are used to identify and track vulnerabilities in a standardized way.
Characteristics of a CVE
- CVE ID: A unique identifier in the format of CVE-YYYY-XXXXX, where YYYY is the year and XXXXX is a unique number.
- Description: A brief summary of the vulnerability, including its impact and affected products.
- References: Links to additional information about the vulnerability, such as advisories, patches, and articles.
CVE Life Cycle
- CVE Request: A request is made to assign a CVE ID to a newly discovered vulnerability.
- CVE Assignment: A CVE ID is assigned to the vulnerability.
- CVE Publication: The CVE is published on the MITRE CVE website.
- CVE Updates: The CVE is updated as new information becomes available.
CVE Categories
- High: Vulnerabilities that can be exploited remotely, resulting in severe impact.
- Medium: Vulnerabilities that require local access or have a moderate impact.
- Low: Vulnerabilities that require significant user interaction or have a minimal impact.
Benefits of CVEs
- Standardization: CVEs provide a standardized way to identify and track vulnerabilities.
- Improved Communication: CVEs enable clear communication about vulnerabilities among security professionals, vendors, and users.
- Efficient Patching: CVEs help prioritize patching efforts by highlighting the most critical vulnerabilities.

CVE Life Cycle
- A CVE life cycle starts with a CVE request to assign a CVE ID to a newly discovered vulnerability.
- A CVE ID is assigned to the vulnerability in the assignment stage.
- The CVE is published on the MITRE CVE website after assignment.
- The CVE is updated as new information becomes available.
CVE Categories
- High-severity vulnerabilities can be exploited remotely, resulting in severe impact.
- Medium-severity vulnerabilities require local access or have a moderate impact.
- Low-severity vulnerabilities require significant user interaction or have a minimal impact.
