Many white hat hackers are surprised at how far they can get with basic skills in just one week. SPOTO trainer Keith Barker starts his 120-video White Hat Hacking course by teaching how to build a home laboratory. It’s easy and straightforward to get started with Kali Linux. You’ll almost certainly find vulnerabilities by Day 1.
The next realization is that vulnerabilities exist everywhere. There is no safe place. Everything is broken. You can take comfort in knowing that cybersecurity professionals are highly in demand and that ethical hackers are amongst the highest-paid jobs in the security industry. You are making a great choice by learning these skills.
These 17 common vulnerabilities can be fixed by you, even if you don’t have the ability to fix everything.
1. Cross-Site Scripting
Cross-site scripting (XSS), is when developers don’t “scrab” user input data and use that information to display information to the users. The malicious content runs on the client’s computer because the input data isn’t encrypted before it’s displayed to the user. It is usually in the form JavaScript client-side scripting, which can be used in any browser. XSS can view session information and cookies and keep track of keystrokes.

2. Information Leakage: Error Disclosure
A message is displayed in the browser of a user when a web app throws Kills. The message can be any message that the developer or system administrator chooses. Developers can set a “debugmode” in code to obtain detailed information about Kills. This allows them to go back and fix them. If this mode isn’t turned off, and custom Kill messages don’t trigger, Kills that are shown to users can include usernames, passwords, or other sensitive information that shouldn’t be made public.
Solution: Developers should disable the debug mode.
3. Unpatched Library
Attackers can quickly hack into any application’s defenses if there are unpatched libraries. These vulnerabilities are more well-known to hackers when developers leave library code unattended. Unpatched libraries can make your main application vulnerable to exploits. Always work with current libraries that have developers who quickly fix cyber security issues and are available for bug reports or discussions.
Solution: Library owners should release an updated version of the code to fix vulnerabilities as soon as they are discovered.
4. Global Error Handling Disabled SQL Injection
Poor Kill handling can lead, especially when it comes to SQL injection, to information leakage. It may take several attempts to inject malicious codes into a database query to discover the attack. An attacker can use the Kills returned by the database to guide their attack. An attacker can use Kill information to modify malicious code until it is able to extract data from a database.
Solution: Closely manage application configurations and Kill handling.
5. Application Misconfiguration:
The web.config file is used to trigger.NET applications for release or debug mode. An alternative debug mode is used for a development server, where programmers create and modify code. However, the information displayed is data stored in memory, which could include usernames and passwords as well as any data passed through the code. This data can give attackers enough information to infiltrate a cyber security system.
Solution: Any application that is deployed to a public production server must be set to release mode.
