海外TECH	DEV Community	How I got into Computer Engineering?	https://dev.to/midnqp/how-i-got-into-computer-engineering-58gb	How I got into Computer Engineering It all started in the age of Smartphones were pretty rare then But I had one The other thing I had was Broadband Internet One day I woke up from sleep and said why not combine both And then I tried to do it And I failed Kept failing until I succeeded to turn on the hosted network at my Windows laptop and share bandwidth That s how I could use Internet on my tiny smartphone as Wi Fi without using a Network Router That was a victory And victories feel good Really good Instantly got interested in computers Started learning to code the same day Started with learning C and started respecting Denis Ritchie To the years old me C wasn t easy But to my unquenching curiosity it wasn t hard I even learnt pointers Kept learning it until I realized Python is a better one to start with Fast forward and now I m a Web Systems Engineer at a Dubai based startup And I got my first paycheck before all of my friends and peers Lesson of the DayIf you have a dream that you believe in keep chasing that dream	2021-09-06 20:45:02
海外TECH	DEV Community	WHAT IS SQL INJECTION? TYPES, EXAMPLES, PREVENTION	https://dev.to/sudip_sg/what-is-sql-injection-types-examples-prevention-541e	WHAT IS SQL INJECTION TYPES EXAMPLES PREVENTIONCode injections are the oldest known web application attack vectors with successful hacks leading to a denial of service loss of data integrity data loss and the compromise of entire networks As a result injection based security vulnerabilities rank number one on the OWASP Top Security Risks They allow attackers to apply malicious code into information systems through user input interfaces One such mechanism is a SQL Injection attack that involves the insertion of SQL queries to client input to access and manage backend databases SQL Injection attacks are mostly carried out on web applications that rely on dynamic databases but lack sufficient input validation This article delves into SQL Injection based security risks and the various best practices and tools to prevent such attacks A Deep Dive into SQL Injection VulnerabilitiesSQLi Security AssessmentTypes of SQL Injection AttacksHow Attackers Perform SQLiCommonly Known SQLi Attack Examples amp TechniqueHow to Prevent SQL injection AttacksTools to Prevent Detect and Remediate SQLi VulnerabilitiesSummary A DEEP DIVE INTO SQL INJECTION VULNERABILITIESWhen a malicious user performs an SQL Injection SQLi attack they typically intend to control the web application s database server using malicious SQL statements This allows them to bypass authentication controls required to access and retrieve the contents of the database This usually is initiated by hackers scouting the application firewall for vulnerable user input points Once identified the attacker creates input content known as a malicious payload executing unauthorized SQL injection commands at the back end database Attackers commonly develop SQL injection commands to perform a wide variety of malicious acts such as Retrieving user credentials within the databaseSelecting and outputting crucial system dataAppending or adding new data to a databaseDeleting tables and records from the databaseUsing the back end database server to access the Operating System SQLI SECURITY ASSESSMENTCVSS Vector AV N AC L PR N UI N S U C H I H A N TYPES OF SQL INJECTION ATTACKSSQLi is a common and well documented attack strategy whose success has far reaching business consequences such as unauthorized viewing of credentials and gaining administrative access to the application s database SQLi attacks are categorized based on the following methods used to gain database access IN BAND SQLIThe attacker gathers their results using the same communication channel they use to launch attacks This code injection technique is common since it offers a simple efficient way to access the database server There are several types of in band SQLi including ERROR BASED SQLIThe attacker relies on error messages relayed by the database server to learn about the database structure Sometimes the error messages can provide sufficient data to enumerate the entire database UNION BASED SQLIIn this case the malicious payload uses SQLs UNION operator to combine the results of several SELECT statements to one output which is returned along with the HTTP response BLIND SQL INJECTION INFERENTIAL SQLIIn a Blind SQL injection technique the hacker sends malicious data payloads then reconstructs the database server s structure using the web application s response In Blind SQLi data is not actually retrieved by the web application so the attacker cannot view the results of an attack using the same communication channel they used to launch this type of attack Blind SQL Injection also commonly referred to as the Inferential method is of several types CONTENT BASED SQLIContent Boolean based SQLi attacks force the web application to return different results depending on whether the malicious SQL query returns a TRUE or FALSE result The query result determines whether the content in the HTTP response stays the same or changes As a result the attacker can determine whether the malicious payload returns a true or false result even though the query returns no data from the database TIME BASED SQLIThe attacker sends a query that forces the application to wait for a specific duration before returning a response The attacker uses the response time to determine whether the result of a query is TRUE or FALSE OUT OF BAND SQLIThe attacker uses the same channel to launch the attack and gather results While this attack is uncommon since it relies on certain database server features being enabled it offers an alternative for orchestrating injection attacks if the server responses are unstable HOW ATTACKERS PERFORM SQLI WEB PAGE SQLIWhen a web application asks for user input some attackers supply SQL statements that are run unknowingly on the database This section explores ways in which attackers create payloads that generate valid SQL statements at the user input SQLI BASED ON IS ALWAYS TRUEThe attacker uses an OR statement to access all records in a table When prompted for a User ID the attacker inputs OR If the web application lacks sufficient input validation this statement is accepted the generates a SQL command of the form SELECT FROM Users WHERE UserId OR This query accesses and displays all records in the Users table since is always TRUE SQLI BASED ON “ IS ALWAYS TRUEAttackers use an OR statement to get combinations of related data When prompted for a Username and Password they key in or “ on both fields The database server then executes a command of the form SELECT FROM Users WHERE Name or “ AND Pass or “ This command returns every row in the Users table since OR “ is always true for Usernames and Passwords SQLI BASED ON BATCHED STATEMENTSModern database servers accept batch statements which hackers may exploit to target particular records or tables For instance when prompted for their User ID they input DROP TABLE Suppliers This executes a valid statement of the form SELECT FROM Users WHERE UserId DROP TABLE Suppliers This deletes the table Suppliers from User records COMMONLY KNOWN SQLI ATTACK EXAMPLES amp TECHNIQUESuccessful SQLi attacks can be used to tamper with existing data disclose crucial information gain administrative rights to networks and cause repudiation issues Examples of SQLi attacks on enterprise systems include THE BULGARIAN NATIONAL REVENUE AGENCY DATA BREACHOn th July an anonymous hacker announced that they successfully deployed an SQL injection on the national tax authority s servers The hacker extracted GB of data in folders of csv files that contained names and identification information of over million people The files also included citizens social security payments taxes online betting data debts company activities and revenues collected for over years THE ACCELLION DATA BREACHAttackers used an SQL injection vulnerability to gain initial access to the Accellion File Transfer Appliance FTA and cause a massive data breach affecting multiple companies in different sectors and multiple countries The victims data began to appear on CLOP LEAKS a ransomware forum The zero day vulnerabilities that enabled a successful attack are yet to be fixed as more companies keep reporting compromises of user data HOW TO PREVENT SQL INJECTION ATTACKSPreventing SQLi attacks is a complex and rigorous process since prevention techniques vary according to the programming language used the SQL database engine and the SQLi subtype being addressed This section explores the tools and best practices to prevent SQL Injection vulnerabilities BEST PRACTICES TO PREVENT SQLI VULNERABILITIESSome strategic principles and practices to keep web applications safe from SQLi attacks include TRAINING amp AWARENESSEveryone involved in developing and managing the application should understand the risk and impacts of SQL injections Training should also be extended to users to understand why it is important only to include valid inputs when prompted FILTER USER INPUTA database administrator should never trust user input Internal and public user inputs should all be filtered and validated before being exposed to the database server USE WHITELIST BASED FILTERSAttackers will always develop clever methods to circumvent blacklists Whitelisting prevents attacks using a list that only allows certain users to access the protected system In addition malicious payloads deployed by SQLi injections cannot execute when they don t exist in the whitelist USE UPDATED WEB TECHNOLOGIESSoftware updates often include patches for discovered vulnerabilities Hackers typically rely on these vulnerabilities to deploy malicious payloads Using the latest patched versions of development environments and frameworks will meet compliance standards and keep the web application safe from exploits as most software organizations try to stay ahead of hackers REGULAR SCANNINGAttackers inject malicious input through vulnerabilities they discover in the system code Therefore security teams should undertake a SQL vulnerability assessment using the right tools to find any possible vulnerabilities before attackers can take advantage of them SQL INJECTION PRACTICAL PREVENTION TIPSTo prevent SQL injection attacks treat all user input as potentially malicious and follow some programming guidelines FILTER USER INPUTFor an attacker to successfully execute an SQL injection he needs to plant some code run by the web application s database Therefore all user input should be validated first and limited to the needed characters E g you may ask a user to input a username password and e mail address in a registration form You can limit the allowed characters of these input fields to characters that do not interfere with the database The following example filters out user input for the three values in PHP if preg match A Za z username preg match A Za z password preg match A Za z email echo Invalid Characters else Run Database Command DATABASE MAPPERSMost modern web frameworks provide some abstraction of database handling E g Laravel provides Eloquent queries Created objects are automatically converted and stored or retrieved from the database In the example of the user registration form one could create the user object in the following way user new User user gt username request gt username user gt password request gt password user gt email request gt email user gt save The resulting SQL statement is automatically sanitized and will prevent SQL injections SANITIZE USER INPUT PREPARED STATEMENTSIt may not always be possible to use a database mapper In these cases use prepared statements to create your SQL queries These forms of statements validate and sanitize the user provided values and therefore prevent SQL injections E g in PHP you can create a prepared statement the following way stmt mysqli gt prepare INSERT INTO users username password email VALUES stmt gt bind param sss username password email sss here states that three strings are expected username request gt username password request gt password email request gt email stmt gt execute TOOLS TO PREVENT DETECT AND REMEDIATE SQLI VULNERABILITIESRegular SQL vulnerability assessment scan is the first actionable remediation to keeping web applications safe from SQLi
