#### Introduction
HTTP Input Attack is a set of techniques used by attackers to exploit vulnerabilities in web applications. These attacks can lead to data leaks, system compromise, and other serious consequences. In this article, we will look at the main types of attacks on HTTP input, such as cross-site scripting (XSS), SQL injection, deserialization vulnerabilities, and others. Recommendations for conducting interface pentests to identify and eliminate these vulnerabilities will also be offered.
#### Main types of attacks
1. Cross-Site Scripting (XSS)
– Description: XSS attacks allow attackers to inject malicious scripts into web pages, which are then executed in users’ browsers.
– Example: Injecting JavaScript code through an input form, which is then displayed on the page without proper filtering.
2. Template Injection
– Description: Template attacks allow attackers to inject malicious code into the templates used to generate web pages.
– Example: Injecting malicious code into a template which is then used to display data on a web page.
3. Third Party Component Vulnerability
– Description: Exploitation of vulnerabilities in third party libraries or components that are integrated into the web application.
– Example: Exploitation of a vulnerability in a popular image processing library.
4. HTTP Parameter Pollution
– Description: Attacks in which attackers modify HTTP request parameters to achieve undesirable effects.
– Example: Changing form parameters to bypass server-side validation.
5. SQL Injection
– Description: Injecting malicious SQL queries through input data, allowing attackers to execute arbitrary SQL commands.
– Example: Injecting SQL code through an input form, allowing access to a database.
6. XXE Object Injection
– Description: Attacks that exploit vulnerabilities in XML processing to execute arbitrary commands or access data.
– Example: Injection of malicious XML code, which is then processed by the server.
7. Deserialization vulnerability
– Description: Exploitation of vulnerabilities in the process of data deserialization, which can lead to the execution of arbitrary code.
– Example: Injecting malicious data into a serialized object, which is then deserialized by the server.
8. SSRF Vulnerability
– Description: Attacks in which attackers force the server to make requests to arbitrary resources.
– Example: Using a vulnerability to access internal network resources.
9. Code Injection
– Description: Injection and execution of arbitrary code on the server.
– Example: Injecting PHP code through an input form, which is then executed by the server.
10. Contains Local File / Contains Remote File
– Description: Attacks in which attackers gain access to local or remote files through a web application.
– Example: Exploiting a vulnerability to read server configuration files.
11. Command Execution Injection
– Description: Attacks in which attackers execute arbitrary commands on the server.
– Example: Injecting commands through an input form, which are then executed by the server.
12. Buffer/Format String Overflow
– Description: Attacks that exploit vulnerabilities in the handling of buffers or formatted strings to execute arbitrary code.
– Example: Injecting data that exceeds the buffer size, resulting in arbitrary code execution.
#### Recommendations for conducting interface pentesting
To identify and eliminate vulnerabilities in web applications, it is recommended to conduct regular interface pentests. SlowMist Exchange Security Auditing Software offers a comprehensive approach to security testing, including:
– Analysis of source code for vulnerabilities.
– Penetration testing using various attack methods.
– Assessing the security of third-party components and libraries.
– Checking for vulnerabilities in the server configuration and network infrastructure.
#### Conclusion
HTTP Input Attack poses a serious threat to web application security. Understanding the main types of attacks and conducting regular interface pentests will help protect your systems from intruders. Use best practices and tools like SlowMist Exchange Security Auditing to ensure your web applications are securely protected.
