SEQUEL INJECTION

How to prevent sequel injection attacks.

Sequel injection, also known as SQL injection, is a type of weakness in an application that may allow a malicious individual to access and control an application’s database. By tricking an application into sending unexpected SQL commands, a sequel injection attack may allow attackers to steal or delete data or to cause an application to behave in unintended ways.

For a sequel injection attack to be successful, an application must use untrusted data as part of a database query. Typically, this data comes from data entered into web form fields and which has not been adequately sanitized before it gets added to an SQL query. In this scenario, attackers can enter SQL commands that the database will execute, providing unauthorized access or performing unintended actions.

Preventing sequel injection is relatively easy, yet this vulnerability is still one of the most prevalent and potentially damaging flaws in enterprise applications. Eradicating sequel injection vulnerabilities requires robust application security testing solutions that combine static and dynamic analysis. That’s where Veracode can help.

Stopping sequel injection with Veracode

Veracode’s on-demand application security testing services allow organizations and development teams to deliver secure software more quickly, easily and cost-efficiently. With Veracode, developers can use desktop, web and mobile app security testing technology to find and fix flaws in software that is built, bought and assembled, enabling organizations to address security issues at any point in the SDLC. Veracode services can integrate seamlessly in to agile or waterfall software development processes as well as many other development methodologies.

Identifying sequel injection vulnerabilities is the first step in preventing an attack. Our cloud-based testing services provide both static and dynamic testing to quickly identify flaws and provide step-by-step guidance on how to remediate them. Developers can also:

  • Repair sequel injection vulnerabilities by using parameterized queries that treat parameters as data rather than as part of an SQL command.
  • Remediate sequel injection flaws in legacy systems by escaping inputs before adding them to the query.
  • Mitigate the impact of sequel injection attacks by enforcing least privilege on the database.

Veracode testing solutions for sequel injection.

Our SaaS-based application security testing services for preventing sequel injection and other vulnerabilities includes:

  • Veracode Static Analysis, a service that identifies flaws by scanning binaries and providing results prioritized by severity of the flaw. This testing service is a critical part of demonstrating SarbOx compliance and compliance with other regulatory frameworks.
  • Veracode Web Application Scanning, a service that combines static and dynamic analysis to scan all public-facing web applications for flaws.
  • Veracode Greenlight, a solution that runs in the background of a developer’s integrated development environment and provides immediate alerts when flaws are found as code is being written.
