Everything You Need to Know About OWASP Top 10 2021 Astra Security Blog

User sessions or authentication tokens (particularly single sign-on tokens) aren’t properly invalidated during logout or a period of inactivity. Preventing injection requires keeping data separate from commands and queries. Hostile data is used within object-relational mapping search parameters to extract additional, sensitive records. User-supplied data is not validated, filtered, or sanitized by the application. JavaScript is now the primary language of the web with node.js running server side and modern web frameworks such as Bootstrap, Electron, Angular, and React running on the client.

What is OWASP Top 10?

The Open Web Application Security Project (OWASP) is an open source application security community with the goal to improve the security of software. The OWASP Top 10 is an industry standard guideline that lists the most critical application security risks to help developers better secure the applications they design and deploy.

Since security risks are constantly evolving, the OWASP Top 10 list is revised periodically to reflect these changes. In the latest version of OWASP Top 10 released in 2017, some types of vulnerabilities which no longer represent a serious threat were replaced with ones most likely to pose a significant risk. An updated Top 10 is expected in 2021.

While the OWASP Top 10 is a great place to start securing applications, it certainly should not be considered as an end goal since some of the most-cited vulnerabilities didn’t make it into the OWASP Top 10 2017. To guard against software weakness, defenders need to look more broadly across their information-technolog…  Ещё

With so much sensitive and valuable data now accessible through web applications and services, security controls for resource access must be an integral part of application design, development, and testing. For example, if an API is intended to provide read-only data access, but no access controls are in place to limit HTTP commands only to GET, attackers may be able to modify data using POST or other request types. You could also have a flawed implementation of access control using JSON Web Tokens , where the tokens are used but don’t actually enforce access control. The prevalence of broken authentication is widespread due to the design and implementation of most identity and access controls. Session management is the bedrock of authentication and access controls, and is present in all stateful applications.

When crypto is employed, weak key generation and management, and weak algorithm, protocol and cipher usage is common, particularly for weak password hashing storage techniques. For data in transit, server side weaknesses are mainly easy to detect, but hard for data at rest. Attackers have access to hundreds of millions of valid username and password combinations for credential stuffing, default administrative account lists, automated brute force, and dictionary attack tools.

● Do not ship or deploy with any default credentials, particularly for admin users. ● Uses weak or ineffective credential recovery and forgot-password processes, such as “knowledge-based answers,” which cannot be made safe. ● OWASP Top 10 2017 Update Lessons Webmasters/developers cannot keep up with the pace of the updates; after all, updating properly takes time. This means that a large number of attacks can be mitigated by changing the default settings when installing a CMS.

What’s new in the 2021 list?

One strategy for determining if you have sufficient monitoring is to examine the logs following penetration testing. Applications and APIs will be vulnerable if they deserialize hostile or tampered objects supplied by an attacker. Using frameworks that automatically escape XSS by design, such as the latest Ruby on Rails, React JS. Learn the limitations of each framework’s XSS protection and appropriately handle the use cases which are not covered. Automated tools can detect and exploit all three forms of XSS, and there are freely available exploitation frameworks. A repeatable hardening process that makes it fast and easy to deploy another environment that is properly locked down. Development, QA, and production environments should all be configured identically, with different credentials used in each environment.
