[gafimiv406]

Like any software, websites are subject to the threat of hacking, data leakage or other illegal actions by intruders. In recent years, website building has become very popular - now you can create a web resource even without programming skills. Unfortunately, this leads to the emergence of security vulnerabilities.
In this article, we will briefly discuss the vulnerabilities that a website should be checked for first.

What is a website vulnerability?
A vulnerability is a flaw in a system that can be exploited to intentionally disrupt its functionality or gain unauthorized access to information. It is a gap in the security of a web application or website that can lead to its breakdown, theft of confidential data, hacking, and blackmail by hackers.

Security vulnerabilities are usually found using special software scanners (Vulnerability scanners).
10 Possible Website Vulnerabilities
Since you can check a site for vulnerabilities manually, every webmaster should panama whatsapp number database learn about the most common security issues. These are the vulnerabilities that the scanner reports most often, so we recommend that you familiarize yourself with them and immediately check your website for them.

1. Injections/Injection
If you do not validate input data and prepare operators properly, untrusted data can enter your server along with the request, which will cause malicious code to be executed by your interpreter. This is called injection. An attacker can enter code (SQL, XXE, OS, LDAP, and other types) into a form on your site, so it is important to set up filtering of incoming information.

2. Authentication and session verification issues
The user identification process in the service is often incorrect, which gives hackers the opportunity to intercept the session key or steal credentials. Such vulnerabilities allow them to access records without cracking passwords, including those with administrative rights.

3. XSS
Cross-site scripting is a type of attack that involves injecting malicious code into a web page served by a browser. XSS is primarily dangerous for the users themselves, as it allows them to steal their data, hijack a session, and redirect them to a malicious site. This can subsequently damage the web server.

4. Access control issues
This type of vulnerability includes errors that allow users to perform actions and see data that should be blocked. Attackers use them to bypass the restrictions.

5. Incorrect configuration
Refers to problems in software configuration: using default configurations, open unencrypted data, unused but running services, etc. The software must be kept up to date, and the entire system must be scanned regularly.
