How to prevent soql injection?
The first and most recommended method to prevent SOQL injection is to use static queries with bind variables. Consider the following query. As you’ve learned, using user input (the var variable) directly in a SOQL query opens the application up to SOQL injection. To mitigate the risk, translate the query into a static query like this one:
What are the risks of SQL injection?
When queries are built directly with user data inlined or concatenated directly with the query text, instead of using type-safe bind parameters, malicious input may be able to change the structure of the query to bypass or change application logic. SQL injection flaws are extremely serious.
How to become more skilled at preventing injection attacks in Salesforce?
To become even more skilled at preventing injection, head over to the Develop Secure Web Apps trail, which covers all these vulnerabilities in depth, including Salesforce Object Query Language (SOQL) and Apex vulnerabilities. 1 Which of the following is a type of cross-site scripting (XSS) attack?
Is apex vulnerable to SQL injection?
SQL injection flaws are extremely serious. A single flaw anywhere in your application may allow an attacker to read, modify or delete your entire database. Apex does not use SQL, but its own database query language, SOQL (Salesforce Object Query Language).
Can SQL injection be prevented?
How to Prevent an SQL Injection. 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.
What is the best defense against SQL injection?
You should always use parameterized statements where available, they are your number one protection against SQL injection. You can see more examples of parameterized statements in various languages in the code samples below.
What are the methods used to protect against SQL injection attack?
18 Steps to Prevent SQL Injection AttacksValidate User Inputs. ... Sanitize Data by Limiting Special Characters. ... Enforce Prepared Statements and Parameterization. ... Use Stored Procedures in the Database. ... Actively Manage Patches and Updates. ... Raise Virtual or Physical Firewalls. ... Harden Your OS and Applications.More items...•
What are three ways to mitigate SQL injection threats?
There are several methods to mitigate the threat of SQL injection such as the use of parameterized database queries, database firewalls, and whitelist input validation.
Does ORM prevent SQL injection?
The benefits of using an ORM tool include quick generation of an object layer to communicate to a relational database, standardize code templates for these objects, and that they usually provide a set of safe functions to protect against SQL Injection attacks.
How is SQL injection detected?
Detection methods range from checking server logs to monitoring database errors. Most network intrusion detection systems (IDS) and network perimeter firewalls are not configured to review HTTP traffic for malicious SQL fragments, making it possible for an attacker to bypass network security boundaries.
What are the two types of SQL injection attacks?
The two most common types of in-band SQL Injection are Error-based SQLi and Union-based SQLi.
Which of the following methods prevent server side injection?
The best way to prevent server-side template injection is to not allow any users to modify or submit new templates. However, this is sometimes unavoidable due to business requirements.
What is SQL injection 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.
How can we prevent SQL injection in dynamic query in SQL Server?
In general, to prevent SQL injection, we should use parameterized queries in C# code or the stored procedures. Since we focus on the stored procedures, let's look into them. An unsafe way of writing stored procedure to execute SQL dynamic queries: Create Procedure GetData(@input varchar(350))
What types of databases are more vulnerable to SQL injections?
If a web application or website uses SQL databases like Oracle, SQL Server, or MySQL, it is vulnerable to an SQL injection attack. Hackers use SQL injection attacks to access sensitive business or personally identifiable information (PII), which ultimately increases sensitive data exposure.
How to prevent SOQL injection?
Another strategy to prevent SOQL injection is to use typecasting. By casting all variables as strings, user input can drift outside of expectation. By typecasting variables as integers or Booleans, when applicable, erroneous user input is not permitted.
What does SOQL not have?
Here is a list of what SOQL does not have. INSERT, UPDATE, or DELETE statements. It only has SELECT statements. Command execution. Wild cards for fields; all fields must be explicitly typed. JOIN statement; however, you can include information from parent objects like Select Name, Phone, and Account.Name from Contact.
What is SQL injection?
An SQL injection is a technique that attackers apply to insert SQL query into input fields to then be processed by the underlying SQL database. These weaknesses are then able to be abused when entry forms allow user-generated SQL statements to query the database directly.
SQL injection prevention techniques
With user input channels being the main vector for such attacks, the best approach is controlling and vetting user input to watch for attack patterns. Developers can also avoid vulnerabilities by applying the following main prevention methods.
Input validation
The validation process is aimed at verifying whether or not the type of input submitted by a user is allowed. Input validation makes sure it is the accepted type, length, format, and so on. Only the value which passes the validation can be processed. It helps counteract any commands inserted in the input string.
Parametrized queries
Parameterized queries are a means of pre-compiling an SQL statement so that you can then supply the parameters in order for the statement to be executed. This method makes it possible for the database to recognize the code and distinguish it from input data.
Stored procedures
Stored procedures (SP) require the developer to group one or more SQL statements into a logical unit to create an execution plan. Subsequent executions allow statements to be automatically parameterized. Simply put, it is a type of code that can be stored for later and used many times.
Escaping
Always use character-escaping functions for user-supplied input provided by each database management system (DBMS). This is done to make sure the DBMS never confuses it with the SQL statement provided by the developer.
Avoiding administrative privileges
Don't connect your application to the database using an account with root access. This should be done only if absolutely needed since the attackers could gain access to the whole system. Even the non-administrative accounts server could place risk on an application, even more so if the database server is used by multiple applications and databases.
What is injection attack?
Injection is the most common type of attack on the web today. Injection attacks occur when untrusted user input is interpreted as legitimate commands to be executed instead of data to be processed. It is essential to guard against leaving your work open to injection attacks when developing code for your organization.
Why use special escape marker?
Use a special escape marker to tell the computer that it should expect an escape character. Be especially careful when escaping special characters—use the specific escape syntax for that interpreter. Developers can use escaping routines to prevent the database from mistaking user input for SQL code.

There are a number of techniques you can use to prevent SOQL injection:
shariq
In other programming languages, the previous flaw is known as SQL injection. Apex does not use SQL, but uses its own database query language, SOQL. SOQL is much simpler and more limited in functionality than SQL.

SOQL Injection Vulnerability in Apex
Below is a simple example of Apex and Visualforce code vulnerable to SOQL injection.
SOQL Injection Defenses
To prevent a SOQL injection attack, avoid using dynamic SOQL queries. Instead, use static queries and binding variables. The vulnerable example above can be re-written using static SOQL as follows:
