Software Vulnerabilities Definition

Software vulnerabilities are weaknesses or flaws present in your code.

Unfortunately, testing and manual code reviews cannot always find every vulnerability. Left alone, vulnerabilities can impact the performance and security of your software. They could even allow untrustworthy agents to exploit or gain access to your products and data. So, you need to know the top 10 most common vulnerabilities.

What Causes Software Vulnerabilities?

Software vulnerabilities are often caused by a glitch, flaw, or weakness present in the software.

The most effective way to prevent software vulnerabilities is to use secure coding standards to enforce security standards.

Top 10 Most Common Software Vulnerabilities

According to the OWASP Top 10, here are the most common vulnerabilities:

1. Insufficient Logging and Monitoring

Insufficient logging and monitoring processes are dangerous. This leaves your data vulnerable to tampering, extraction, or even destruction.

2. Injection Flaws

Injection flaws occur when untrusted data is sent as part of a command or query. The attack can then trick the targeted system into executing unintended commands. An attack can also provide untrustworthy agents access to protected data.

3. Sensitive Data Exposure

Sensitive data — such as addresses, passwords, and account numbers — must be properly protected. If it isn't, untrustworthy agents take advantage of the vulnerabilities to gain access.

4. Using Components with Known Vulnerabilities

Components are made up of libraries, frameworks, and other software modules. Often, the components run on the same privileges as your application. If a component is vulnerable, it can be exploited by an untrustworthy agent. This causes serious data loss or server takeover.

5. Cross-Site Scripting (XSS) Flaws

Untrustworthy agents can take advantage of cross-site scripting flaws to execute their own scripts in the targeted system. In general, cross-site scripting flaws happen in one-of-two ways:

  • Whenever an application includes untrusted data in a new web page without proper validation.
  • Whenever an existing webpage is updated with user-supplied data using a browser API that can create HTML or JavaScript.

6. Broken Authentication

Authentication and session management application functions need to be implemented correctly. If they aren't, it creates a software vulnerability that can be exploited by untrustworthy agents to gain access to personal information.

7. Broken Access Control

User restrictions must be properly enforced. If they are broken, it can create a software vulnerability. Untrustworthy agents can exploit that vulnerability.

8. XML External Entities (XXE)

XML is a popular data format that is used in web services, documents, and image files. You need an XML parser to understand XML data. But if it's poorly configured and the XML input that contains a reference to an external entity, it's dangerous. An untrustworthy agent can cause a DoS.

9. Security Misconfiguration

Security misconfigurations are often the result of:

  • Insecure default configurations.
  • Incomplete or impromptu configurations.
  • Open Cloud storage.
  • Misconfigured HTTP headers.
  • Wordy error messages that contain sensitive information.

10. Insecure Deserialization

Deserialization flaws often result in remote code execution. This enables untrustworthy agents to perform replay, injection, and privilege escalation attacks.

How to Prevent Software Vulnerabilities

Here are the three most efficient and effective practices to prevent software vulnerabilities.

1. Establish Software Design Requirements

Establish software design requirements. Define and enforce secure coding principles. This should include using a secure coding standard. This will also inform how to effectively write, test, inspect, analyze, and demonstrate your code.

2. Use a Coding Standard

Coding standards — such as OWASP, CWE, and CERT — enables you to better prevent, detect, and eliminate vulnerabilities. Enforcing a coding standard is easy when you use a SAST tool — like Klocwork. Klocwork identifies security defects and vulnerabilities while the code is being written.

3. Test Your Software

It is essential that you test your software as early and often as possible. This helps to ensure that vulnerabilities are found and eliminated as soon as possible. One of the most effective ways to do this is by using a static code analyzer — like Klocwork — as part of your software testing process.

As part of your development pipeline, static analysis complements your testing efforts. Tests can be run during CI/CD integration as well as nightly integration testing.

Static code analyzers automatically inspect your code as it’s being written to identify any errors, weaknesses, or bugs. You can even apply any software vulnerability definition that would be applicable.

How Klocwork Prevents Software Vulnerabilities

Klocwork for C, C++, C#, Java, and JavaScript identifies security, quality, and reliability issues. This helps you enforce compliance with coding standards. And it ensures that your code is safeguarded against vulnerabilities.

By using Klocwork, you will also receive the following benefits:

  • Detect code vulnerabilities, compliance issues, vulnerabilities definitions, and rule violations earlier in development. This helps to accelerate code reviews as well as manual testing efforts.
  • Enforce of industry and coding standards, including CWE, CERT, PA DSS, OWASP, and DISA STIG.
  • Report on security compliance over time and across product versions.
