What are website vulnerabilities?

Website vulnerabilities are weaknesses in the code or configuration of a website that can be exploited by attackers to gain unauthorized access to data or disrupt the website. These vulnerabilities can be caused by bugs in the code, server misconfiguration, or outdated versions of the software.

What are the vulnerabilities?

There are many types of vulnerabilities that can be present on a website. For example, SQL injections allow attackers to access a website's database and steal or change information. Cross-site scripting (XSS) allows you to inject malicious code into website pages and execute it on visitors' computers. Incorrect server configuration can lead to the leakage of confidential information or unauthorized access to files.

How to detect vulnerabilities?

To detect vulnerabilities on a site, you can use special tools, such as vulnerability scanners. They automatically check the site code and configuration for known vulnerabilities and provide a report with recommendations on how to fix the problems found. It is also possible to conduct regular security audits with the help of specialized companies or independent experts.

How to protect the site from vulnerabilities?

To protect the site from vulnerabilities, it is necessary to regularly update the software used and monitor the release of security patches. It is also important to properly configure the server and use safe development practices to avoid coding errors. Regular security audits and the use of vulnerability scanners also help to detect and fix problems in a timely manner.

What to do if a vulnerability is discovered?

If a vulnerability is found on a site, immediate action must be taken to fix it. This may include updating the software, changing the server configuration, or fixing bugs in the code. It is also important to inform users of possible risks and take steps to minimize potential harm.

Vulnerabilities in a site pose a serious threat to the security of data and the operation of a site. To ensure protection, you need to regularly conduct security audits, use vulnerability scanners, and stay tuned for software updates. If a vulnerability is discovered, immediate action must be taken to fix it.

What are the high-risk site vulnerabilities?

High-severity vulnerabilities include SQL injection vulnerabilities, XSS cross-site scripting vulnerabilities, source code leaks in pages, backup files in websites, files containing SVN information in websites, and arbitrary Resin file read vulnerabilities in websites.

1. SQL Injection Vulnerability: The website program ignores the validation of the SQL statement contained in the input string, causing the contained SQL statement to be mistaken by the database for a legitimate SQL command and executed, and various sensitive data in the database being stolen.

2. XSS Cross-Site Scripting Vulnerability: The website program ignores the validation of special characters and strings in the input string. This allows an attacker to trick a user into visiting a page containing malicious JavaScript code. For malicious code to be executed in the user's browser. As a result, the permissions of the target user are stolen or the data is tampered with.

3. Page Source Code Leaked: The page source code is leaked, which can leak the key logic of the website service and the customized account password that an attacker can use to gain access to the site.

4. The website has backup files: The website has backup files, such as database backup files, website source code backup files, etc. Attackers can use this information to more easily obtain permissions on the website, which results in the website being hacked.

5. The website has a file containing SVN information: The website has a file containing SVN information. This is a private version controller file of the website's source code that contains the address of the SVN service represented by the private file. name, SVN username, etc. This helps the attacker better understand the structure of the website and helps the attacker infiltrate the website.
