What is Cross-site Scripting?
According to OWASP Top 10, XSS is the second-most prevalent issue found in the majority of web applications. By using XSS, attackers can bypass the Same Origin Policy (SOP) in a vulnerable application by entering malicious code which is mistakenly interpreted as user input. This can be done with technologies like VBScript, ActiveX, Flash and even CSS, but JavaScript attacks are the most common.
XSS differs from SQLi because it does not target the database of web applications; it mostly limits itself to their front end.
These kinds of attack can be non-persistent, persistent and DOM-based. The consequences of XSS attacks can be very damaging, especially when combined with social engineering.
Websites or web interfaces can become corrupted and unsafe. Cookies and authentication information can be stolen, leading to identity theft. By hacking a vulnerable company website, attackers can gain control of the company’s computer clients.

How can cross-site scripting vulnerabilities be prevented?
Sanitize HTML inputs
… specify which tags are designed as “safe” in the HTML documents created by user inputs, by blacklisting and whitelisting. Useful for websites that rely on user inputs, like forums, but it should not be used alone to combat XSS.
Escape user input
Use Content Security Policy (CSP)
Use a SAST solution
Make XSS Prevention Part of your DevOps Process
Kiuwan Code Security integrates with leading CI/CD tools so that you can take a DevOps approach to XSS prevention. Scan your code securely on your own local server, and then share scan results in the cloud to collaborate with the team. Generate an automatic action plan and calculate the effort required to remediate vulnerabilities. Apply what-if analysis and customize the plan to fit your needs, then track the team’s progress toward your goals.
