SQLmap Automated SQL injection tool

  SQLMap is an open-source penetration testing tool that automates the process of detecting and exploiting SQL injection vulnerabilities in web applications. It is written in Python and is available on Linux, Windows, and macOS. SQLMap is a powerful tool that can be used by security professionals, penetration testers, and ethical hackers to identify and exploit SQL injection vulnerabilities in web applications. SQL injection is a type of security vulnerability that allows an attacker to manipulate a web application's SQL database by injecting malicious SQL statements into an entry field, such as a search field or a login form. This can lead to data theft, data manipulation, and even complete control of the web application and its underlying database. SQLMap works by sending various SQL injection techniques to the targeted web application to identify vulnerabilities. It supports a wide range of database management systems such as MySQL, Oracle, PostgreSQL, Microsoft SQL

SQL Injection Prevention Cheat Sheet

This article is focused on providing clear, simple, actionable guidance for preventing SQL Injection flaws in your applications. SQL Injection attacks are unfortunately very common, and this is due to two factors: the significant prevalence of SQL Injection vulnerabilities, and the attractiveness of the target (i.e., the database typically contains all the interesting/critical data for your application). It’s somewhat shameful that there are so many successful SQL Injection attacks occurring, because it is EXTREMELY simple to avoid SQL Injection vulnerabilities in your code. SQL Injection flaws are introduced when software developers create dynamic database queries that include user supplied input. To avoid SQL injection flaws is simple. Developers need to either: a) stop writing dynamic queries; and/or b) prevent user supplied input which contains malicious SQL from affecting the logic of the executed query. This article provides a set of simple techniques f

XPATH Injection

Similar to SQL Injection , XPath Injection attacks occur when a web site uses user-supplied information to construct an XPath query for XML data. By sending intentionally malformed information into the web site, an attacker can find out how the XML data is structured, or access data that he may not normally have access to. He may even be able to elevate his privileges on the web site if the XML data is being used for authentication (such as an XML based user file). Querying XML is done with XPath, a type of simple descriptive statement that allows the XML query to locate a piece of information. Like SQL, you can specify certain attributes to find, and patterns to match. When using XML for a web site it is common to accept some form of input on the query string to identify the content to locate and display on the page. This input must be sanitized to verify that it doesn't mess up the XPath query and return the wrong data. XPath is a standard language; its notation/sy

SQL Injection Bypassing WAF

A SQL injection attack consists of insertion or "injection" of a SQL query via the input data from the client to the application. A successful SQL injection exploit can read sensitive data from the database, modify database data (Insert/Update/Delete), execute administration operations on the database (such as shutdown the DBMS), recover the content of a given file present on the DBMS file system and in some cases issue commands to the operating system. SQL injection attacks are a type of injection attack, in which SQL commands are injected into data-plane input in order to effect the execution of predefined SQL commands. SQL Injection – Basic Concepts There are two types of SQL Injection • SQL Injection into a String/Char parameter Example: SELECT * from table where example = 'Example' • SQL Injection into a Numeric parameter Example: SELECT * from table where id = 123 Exploitation of SQL Injection vulnerabilities is divided into classes a
