A look at Security Vulnerabilities in Code

Operating systems and apps in today’s world are linked over the internet and are updated on a regular basis. The majority of the time, these updates are done to address issues rather than introduce new features. As a result, the system is more resistant to newly installed viruses and malware.

Unfortunately, most software lacks this sort of connection, making it open to hackers. You can ensure that your program isn’t hacked in one of two ways: by accessing it on every system and changing the code every time an attacker appears, or by reducing the vulnerability of your code throughout the development process.

What Are Vulnerabilities?

In the process of developing and coding technology, sometimes mistakes occur. A bug is the result of these mistakes. While bugs aren’t necessarily dangerous (except in terms of the technology’s potential performance), many of them may be exploited by malicious actors, which are referred to as vulnerabilities. Vulnerabilities can be used to induce software to behave in unexpected ways, such as gathering information on the existing security defenses.

When a bug is proven to be a vulnerability, MITRE classifies it as a CVE, or common vulnerability or exposure, and assigns a CVSS (Common Vulnerability Score System) score to represent the risk it poses to your business. Vulnerability scanners use this central list of CVEs as a reference point.

In general, a vulnerability scanner will scan your environment and compare it to a vulnerability database, which has a list of known vulnerabilities. The more information the scanner has, the more accurate its results will be. Developers may utilize penetration testing to determine where the flaws are so that the problem can be repaired and future mistakes can be prevented once a team has received a report of the vulnerabilities.

Vulnerabilities Due to Coding Errors

Software developers start with a specification that explains what the software will do (for example, when button A is pressed, display Account Information). Functional requirements serve as the foundation for developers’ work. A functional “bug” is created when a functional need does not operate as expected.

When features aren’t implemented correctly, security vulnerabilities or defects might arise. When button A is pressed, for example, all accounts’ information is displayed. Alternatively, the functionality may operate, but it can be used by threat actors to get access to sensitive data. Unexpected usage scenarios that cause the program to “break” or behave in unexpected ways must be accounted for through security.

Software security is rarely part of the functional specification, and just requiring that the software be “secure” isn’t enough. Previously, software developers were evaluated on a functional basis. They were doing their jobs correctly if they provided features timely. Security was never addressed until roughly 20 years ago, and secure coding is currently taught in computer science curricula only occasionally.

What are the main security vulnerabilities?

A security vulnerability is a defect, mistake, or weakness discovered in a security system that might be exploited by a threat agent to penetrate a protected network. There are many different types of security vulnerabilities, however, the following are some of the most frequent.

Broken Authentication: When authentication credentials are stolen, malicious actors can hijack user sessions and identities in order to impersonate the original user.

SQL Injection: One of the most common security vulnerabilities, SQL injections, is to access database content by injecting malicious code. An SQL injection that is successful can allow attackers to steal sensitive data, fake identities, and engage in a variety of other malicious actions.

Cross-Site Scripting: A Cross-site scripting (XSS) attack, like a SQL Injection, injects malicious code into a website. On the other hand, a Cross-site scripting attack targets website users rather than the website itself, putting sensitive user information at risk.

Cross-Site Request Forgery: The goal of a Cross-Site Request Forgery (CSRF) attack is to mislead an authorized user into doing something they didn’t want to do. This, along with social engineering, has the potential to mislead people into revealing personal information to a malicious actor by accident.

Security Misconfiguration: A “Security Misconfiguration” is any component of a security system that can be exploited by attackers due to a configuration error.

Lack of Focus on Security, Leads to Code Exposure

Mistakes or vulnerabilities made by developers in software solutions when creating code are one cause of code vulnerability. These defects are frequently caused by bad coding habits, practices, and policies, as well as an ever-changing threat landscape and the peculiarities of various coding languages. Threat actors concentrate their efforts on identifying and exploiting these vulnerabilities, frequently for financial gain.

Professional & Managed Tools like Codegrip to help solve them

To control the risks associated with code exposure, use application security testing (AST) solutions across the SDLC. Here are some of the most important software security solutions that may assist your team in resolving code exposure.

Static Application Security Testing- capacity to check uncompiled/unbuilt code for vulnerabilities in the most common coding languages automatically.
Interactive Application Security Testing- the capability of constantly monitoring application activity and detecting vulnerabilities that can only be identified on a running application
Open Source Analysis- capacity to include open-source analysis in the SDLC and manage open-source components while ensuring that susceptible components are removed or changed before they cause an issue
Developer Software Security Education- a comprehensive, interactive, and engaging software security training platform that sharpens the skills developers need to prevent security risks, repair vulnerabilities and build secure code.
Using an automated tool like CodeGrip, which analyses your code and checks it for any security problems, is a better alternative. It identifies code defects and displays them apart from other concerns such as code smells and bugs. All code vulnerabilities are shown in a separate tab and are also highlighted in your code. You may use the proposed solution to figure out what modifications need to be made to eliminate the security vulnerabilities. CodeGrip ensures that your code remains secure throughout assaults and is free of security vulnerabilities.


A web application’s vulnerabilities harm all of the entities that are connected to it. These vulnerabilities must be addressed in order to offer a safe and secure environment for users. Attackers can use these weaknesses to get access to a system, breach it, and escalate privileges. Depending on the demands and attack vectors of malicious actors, the consequences of a hacked web application can range from stolen credit card credentials and identity theft to the leakage of extremely private information.
