CROSS-SITE SCRIPTING

Stopping a cross-site scripting attack.

Addressing a cross-site scripting vulnerability is a fairly simple matter when you have the right solutions.

Cross-site scripting is a serious threat and continues to be one of the most prevalent types of attacks on enterprise security. Essentially, cross-site scripting attacks involve malicious script that is injected into trusted websites. Most attacks target scripts that are embedded in a webpage and executed in the user’s browser rather than on the server side. When an attack is successful, malicious individuals may be able to control the victim’s browser or an account on the vulnerable web application.

Remediating cross-site scripting flaws in code is straightforward when you have tools that can easily scan code and identify vulnerabilities at any point in the SDLC. That’s why so many organizations and development teams choose application security testing solutions from Veracode.

Avoiding cross-site scripting vulnerabilities with Veracode.

Veracode provides leading application security solutions that help to protect the software that is critical to business operations. Built on a cloud-based platform, Veracode’s comprehensive testing methodologies allow developers and administrators to test for vulnerabilities throughout the development process, from inception through production. From tools for the developers IDE to static analyses and web vulnerability scanners, Veracode provides on-demand, SaaS-based services that enable organizations to embed security testing into development without sacrificing agility or speed.

Fixingcross-site scripting errors in applications involves three steps:

  • Applications must validate data input to the web application from user browsers.
  • All output from the web application to user browsers must be encoded.
  • Users must have the option to disable client-site scripts.

Veracode’s testing services can quickly scan control and data flow for an application and accurately identify cross-site scripting and other flaws in code that is built in-house or acquired from third-parties. Scan results are returned quickly – usually within four hours – and include a step-by-step remediation plan that helps to accelerate fixes and prioritize efforts.

Veracode testing methodologies for cross-site scripting.

Veracode provides multiple testing and security analysis services to help mitigate cross-site scripting flaws:

  • Veracode Static Analysis scans binaries to identify errors in code that is built, bought or assembled.
  • Veracode Greenlight provides immediate feedback within an IDE, alerting developers to potential flaws as code is being written.
  • Veracode WAS is a web application scanner that discovers all public-facing web applications and performs lightweight and authenticated scans to identify cross-site scripting vulnerabilities.
  • Veracode Vendor Application Security Testing helps to identify vulnerabilities in third-party code.
  • Veracode Software Composition Analysis helps to prevent cross-site scripting errors in open source components and commercial code.
