Securing against SQL injection removes this avenue of attack and protects an organization from within. A login that has limited server access may be able to exploit SQL injection to gain additional access that normally would not be allowed.

While we never want to consider internal employees as potential bad actors, we need to accept that in an organization large enough, someone may eventually resort to bad behavior, given a good enough opportunity. By greatly restricting what characters are allowed, we can head off SQL injection before it has a chance to rear its ugly head. In this scenario, there are enough protections in place to ensure that my attempts at triggering errors or breaking TSQL strings would fail. Are they treated like a string (as they should be) or do they interfere with TSQL or app code, causing unexpected behavior?

I’m curious about what happens when special characters are entered into these text fields. Hackers play the role of quality assurance and will enter every odd combination of characters, symbols, or data length in an attempt to trigger an error or unexpected behavior. This is the source of most SQL injection attacks. Alerting on these logs can give us advance notice of potential attacks and the details of how they are being performed, as well as their origin.Īny place where users can enter freeform data should be given careful attention. Maintaining and monitoring weblogs can be an arduous task, but can provide valuable insight into areas in which hackers are trying to maliciously access a given site. In addition, the application should obscure any URL contents that might be used to gain undesired app information, such as primary key IDs or entity names. If a URL contains search strings, security descriptors, or other sensitive components, then an application needs to validate URL contents prior to processing them. This method is hard to detect, requires little skill, and determining success or failure is relatively quick. While most modern web sites protect against this, URL hacking is still one of the most common ways in which someone attempts to gain access to data. Information about schema can be used to determine other ways to attack a server and ultimately steal data. User names can be used to intentionally fail logins and lockout users. The intention is a query that returns data for a given user ID and password, but since there are no protections on either input, the TSQL can easily be hacked into returning additional data from the table.īeing able to get a list of usernames, tables, passwords, or any related data can be quite dangerous, even if that data is incomplete. This makes it a valuable tool, but one where its users need to ensure that each of those variables is cleansed appropriately prior to use. Dynamic SQL provides the ability to splice variables into TSQL at runtime, allowing us to accomplish tasks that otherwise could be time-consuming or inefficient. This is often mistaken as the only source of SQL injection, which can be detrimental to security efforts. SQL injection requires some entry point to execute. Despite years of research, identification, and attention, SQL injection persists and continues to plague organizations via unprotected endpoints.įor our work, we will consider a SQL injection attempt successful if a user can access any data or SQL Server components that they are not normally authorized to access. This threat is the most frequent and consistently rated top security exploit in the history of database software. SQL injection is a subset of an even larger exploit known as an injection, which also includes application code, web components, networking hardware, and the other various components that make up the framework of an application.

The authorized path allows us to exclude traditional hacking, as well as social engineering and other exploits that clearly are not relevant here.

Unauthorized code includes absolutely anything from security commands to string searches to schema changes. We’ll also discuss misconceptions and myths that often hinder our security efforts along the way.ĭefinitions vary amongst professionals, but I prefer the broadest one possible: SQL Injection is any attempt to run unauthorized code on a SQL Server via an authorized path.

This article takes a modern look at SQL Injection and the many ways in which it persists, despite our knowledge into what it is, what causes it, and how to eliminate it. Setting aside social engineering and non-technical attacks, SQL injection remains one of the top security threats to our data, as well as one of the most misunderstood.

Some linger and continue to plague software development and will continue to do so for years to come. Many security vulnerabilities are discovered, patched, and go away forever.
