Static Analysis

Unfortunately, the list of software security vulnerabilities is continuously growing, which is why it is important for you to be familiar with the Common Vulnerability Exposures (CVE) list.

Here, we explain what is the Common Vulnerabilities and Exposures (CVE) list and how it can help ensure that your software is secure.

What Is CVE?

Common Vulnerabilities and Exposures (CVE) is a list of publicly known cybersecurity vulnerabilities and exposures. Each item on the list is based upon a finding of a specific vulnerability or exposure found in a specific software product, rather than a general class or kind of vulnerability or exposure.

CVE has been designed to make it easier to link information from vulnerability databases, and allow comparison of security tools and services. The list is made up of a collection of CVE Identifiers assigned to each vulnerability and exposure.

What Is the Difference Between CVE and CWE?

The difference between CVE and CWE is quite simple. CVE refers to a specific instance of a vulnerability within a product or system. While CWE refers to types of software weaknesses. So, in effect, CVE is a list of known instances and CWE is a reference book of software vulnerabilities.

What Is the Difference Between CVE and CVSS?

The difference between CVE and CVSS is this: CVE is a list of vulnerabilities while CVSS is the overall score assigned to a particular vulnerability. What's more, CVSS and CVE work together in order to help you prioritize software vulnerabilities.

What Is a CVE Identifier?

CVE Identifiers are unique identifiers for assigned to publicly known cybersecurity vulnerabilities. The Identifiers are used as a standard method for identifying vulnerabilities and for cross-linking with other repositories.

Each Identifier includes the following:

  • An identifier number.
  • Indication of “entry” or “candidate” status.
  • Brief description of the security vulnerability or exposure.
  • Any pertinent references.

What’s Included on the CVE List?

The CVE list catalogs several types of software vulnerabilities, including:

  • Denial of Service (DoS)
  • Code Execution
  • Buffer Overflow
  • Memory Corruption
  • SQL Injection
  • Cross-Site Scripting (XSS)
  • Directory Traversal
  • HTTP Response Splitting

It’s important to be able to identify each and every vulnerability that may be present in your code, and static analyzers — like Klocwork — are the most effective tools to identify and fix software security vulnerabilities.

How to Fix CVEs?

To fix common vulnerabilities and exposures, follow these four steps:

  1. Establish software design requirements, which includes defining and enforcing secure coding principles. This helps to inform how to effectively write, test, inspect, analyze, and demonstrate your code.
  2. Use a coding standard — such as OWASP, CWE, and CERT — to help prevent, detect, and eliminate vulnerabilities.
  3. Implement security checks into your CI/CD pipeline to identify software security vulnerabilities early. In addition, this helps to enforce good coding practices.
  4. Test your code as early and often as possible to ensure that vulnerabilities are found and eliminated.

How to Address Common Vulnerabilities and Exposures With SAST

The best way to address common vulnerabilities and exposures is to develop secure and safe software by using an automated testing tool — like SAST.

SAST tools identify and eliminate security vulnerabilities and software defects early on in development. This helps to ensure that your software is secure, reliable, and compliant.

By using SAST tools, you are able to

  • Identify and analyze security risks and prioritizes severity.
  • Fulfill compliance standard requirements.
  • Apply and enforce coding standards, including CWE, CERT, OWASP, and DISA STIG.
  • Verify and validate through testing.
  • Achieve compliance and get certified faster.

Klocwork SAST for C, C++, C#, and Java. It helps you apply a coding standard and eliminate software defects and vulnerabilities early on in development, which helps to ensure you’re your software is secure and reliable.
