So if a user in MySQL 5. But if this were a code via a malicious hacker, then they could easily conduct this attack via a 3rd party site. The effect of this attack on a system that has several databases and users and whose buffer pool cache is large is very detrimental! There can be three folds of risks here:. But, this has also been resolved in MySQL 5. This escapes special characters in a string for use in an SQL statement. One example of a weak, database design would be one that is missing constraints — foreign key or check constraints.
Another design flaw can be when database records on a numeric primary key value start off with a 1. Such a number can easily be guessed or used for exploitation in SQL Injections.
The DBMS thrown error or warning must ideally never be shared with the end user of an application or a website. The true MySQL error code from the DBMS may give up a lot of information about the database design table or column structures , application or website design.
A cryptic or hidden MySQL error message that is translated from its original form should be displayed to the end user. The most common way to handle SQL failures is as this article mentions on page 8 see footnote for reference:. The Least Privilege for Database Accounts specially come into play on Cloud Computing or hosting provider sites where the same server hosts multiple sites or databases or both.
If someone compromises one account or finds an SQL injection hole on one site, the attacker may then be able to access all of the data against other databases as well. Defense in Depth would then be violated. Creating separate, and limited accounts for each database is important in both shared and unshared hosting environments but it specially begs for attention owing to the exploits that SQL Injection can yield.
Prepared queries, also called prepared statements, solve a great many of the aforementioned risks. The placeholders are typically type-specific—for example, int for integer data and text for strings—which allows the database to interpret the data strictly.
When you pass the SQL Statement to prepare it is then parsed and compiled by the database server. With execute, the prepared statement is added with the parameter values you specify.
Note here that the parameter values are added with the compiled statement, not with a SQL string. We know that SQL injection conducts itself by fooling the script into including malicious text when it creates SQL to push to the database. By separately sending the SQL statement from the parameters, we limit or eliminate the vulnerability of that unknown factor.
Prepared Statements have the added benefit of having higher performance as it is only compiled and parsed once per session. It is a more infrastructure level documentation although a fair bit of coding and SQL is also shown in this. Using codes and techniques in this documentation, many applications can easily be proven to be exploitable via SQL Injection attacks. It also discusses some best practices and gives suggestions on how to prevent SQL Injection as best as possible.
