This is when there is a failure to properly invalidate session IDs, allowing attackers to exploit an authenticated session of a legitimate user. Make sure you apply protection horizontally (across all data) and vertically (across all levels of access privileges). External security audits can also help ensure that you apply the best practices of website security. While you may conduct automated scans and regularly test for any web application vulnerabilities, those efforts will be in vain unless you know what to look for. In a clickjacking attack, the user is usually already on the attacker's site and tempted to click a button promising great discounts or the secret to eternal youth. How to Prevent It Just one such vulnerability can cause serious consequences, as confirmed by headline-grabbing data breaches. The encryption key should always be separated from the application server. The benefit of effective web application vulnerabilities prioritization Effective prioritization will help you stay focused on the vulnerabilities that pose the greatest risk to your organization and maximizes the value of the time and effort you spend, ultimately strengthening your overall security posture. XML external entity attacks can also result in remote code execution, Server Side Request Forgery (SSRF), and more.

They can use this information to access and modify or even destroy the information, and to attack the underlying system. Attacks with JavaScript sniffers were the most dangerous attacks on individuals in 2018– 2019. What approach should you take? OWASP (Open web application security project) community helps organizations develop secure applications. Attackers typically use these attacks to collect vital customer information such as their contact information, passwords, or even credit card info. In addition to that, the session timeout should also be handled properly.

While the best solution is to use manual code review for critical functionality in large and complex applications, you should also use SAST tools to detect XXE in source code. Use strong encryption methods.

Patch or upgrade all the XML processors and libraries that the application or its underlying OS is using.

The attack was fairly grand scale and merited responses from Akamai, Microsoft and Amazon Web Services, to name a few.
