Which tool could be used for detecting vulnerability through SQL injection?
Table of Contents
Mole or (The Mole) is an automatic SQL injection tool available for free. This is an open source project hosted on Sourceforge. You only need to find the vulnerable URL and then pass it in the tool. This tool can detect the vulnerability from the given URL by using Union based or Boolean based query techniques.
Is SQL injection a vulnerability?
SQL injection is a web security vulnerability that allows an attacker to interfere with the queries that an application makes to its database. It generally allows an attacker to view data that they are not normally able to retrieve.
What is the best control to address SQL injection vulnerabilities?
The only sure way to prevent SQL Injection attacks is input validation and parametrized queries including prepared statements. The application code should never use the input directly. The developer must sanitize all input, not only web form inputs such as login forms.
What is jSQL injection?
jSQL Injection is a lightweight application used to find database information from a distant server. jSQL is free, open source and cross-platform (Windows, Linux, Mac OS X, Solaris).
What is the main difference between a normal SQL injection and a blind SQL injection vulnerability?
Blind SQL injection is nearly identical to normal SQL Injection, the only difference being the way the data is retrieved from the database. When the database does not output data to the web page, an attacker is forced to steal data by asking the database a series of true or false questions.
How do stored procedures prevent SQL injection?
The easiest way to prevent SQL injection from happening, is to use parameters and sp_executesql to execute the dynamically generated statement. The above mentioned statement deletes all the tables present in the DataBase. After the “–“ (double hyphen) the sql treats all the written query as comments.
How is SQL injection performed?
To perform an SQL injection attack, an attacker must locate a vulnerable input in a web application or webpage. When an application or webpage contains a SQL injection vulnerability, it uses user input in the form of an SQL query directly.
How to find SQL injection attack vulnerabilities?
Overview. A SQL injection attack consists of insertion or “injection” of a SQL query via the input data from the client to the application.
How do I prevent SQL injection?
Password hashing
How to detect and stop SQL injection attacks?
– Types of SQL Injection Attack. There are several types of SQL Injection, depending on the method of attack, the information to which the hacker can get access, and on the – Capturing the errors from Extended Events. – Simulating a SQL Injection attack. – Checking on the errors made by an attacker.
How to exploit SQL injection?
SQL in Web Pages. SQL injection usually occurs when you ask a user for input, like their username/userid, and instead of a name/id, the user gives you an SQL statement that you will unknowingly run on your database. Look at the following example which creates a SELECT statement by adding a variable (txtUserId) to a select string. The variable is fetched from user input (getRequestString):
