Top 3 Code Vulnerabilities to Know

For any application, security is an essential concern. Poorly developed websites and applications with security flaws can cost a company millions in lost revenue and damage its brand reputation.

Developers and programmers should be aware of the significance of writing secure code to prevent the most common problems that can occur when writing code. Unfortunately, this results in the most common problem – code vulnerabilities. This article will discuss code vulnerabilities and top vulnerable code examples.

What Are Code Vulnerabilities?

The term “code vulnerability” refers to a security flaw in your software or website. A weakness in your programming puts your data at risk of being hacked. By linking an endpoint to your code, hackers will be able to retrieve data, interfere with your software, or, worse, destroy all. 

Once an attacker has discovered a defect or application vulnerability and figured out how to access it, the attacker can use the vulnerability to commit a cybercrime. These crimes target an application’s designers, users, confidentiality, integrity, or availability of resources. Attackers usually use specific tools or approaches to find and compromise application vulnerabilities.

Types of Code Vulnerabilities

Cross-Site Scripting Attacks

Cross-site scripting is a form of injection vulnerability that injects malicious code into secure websites. This is also known as XSS attacks. The hacker will exploit a hole in a target website or app to deliver malicious code to a user, most typically client-side JavaScript. XSS attacks target the application’s users directly rather than the application’s host.

Businesses and individuals running web apps leave it vulnerable to XSS assaults when they show content from users or untrusted sources without sufficient escaping or validation.

SQL Injection

SQL injection, often known as SQLi attack, is a common type of vulnerability in website and web app code, allowing attackers to take control of back-end operations and access, retrieve, and destroy sensitive data from databases.

Databases are the most efficient and safe way to store a wide range of data. Arguments are frequently used in SQL statements to send data from users to a secure database. Attackers can leverage the parts where the app connects with the database using SQL arguments to obtain access to private information and other confidential regions unless the values in these user-supplied SQL arguments are secured by encryption or prepared statements.

Cryptographic Storage

Insecure cryptographic storage is a vulnerability where important data is not saved securely. Insecure Cryptographic Storage is a set of weaknesses rather than a single flaw.

The collection’s flaws revolve around ensuring the most sensitive data is protected when it has to be. This includes the following:

  •     Ensure you’re encrypting sensitive information
  •     Establishing proper key management and storage
  •     Checking to see whether you’re utilizing any known dangerous algorithms
  •     Checking to see if you’re using your cryptography

Developers frequently presume that just no one will access data storage. However, the registry, databases, and temporary files are all accessible to multiple users of a program or application. These users can exploit temporary, hidden, and registry files to access sensitive data in an unencrypted state.
