Does the OWASP Top 10 Still Matter?

Unsafe deserialization flaws can be introduced when languages and frameworks allow untrusted serialized data to be expanded into an object, often when web applications are communicating user or saving application state. Examples are often found when developers place no restrictions on methods that can self-execute during the deserialization process.

Application security testing can reveal injection flaws and suggest remediation techniques such as stripping special characters from user input or writing parameterized SQL queries. The Top 10 is a great foundational resource when you’re developing secure code. In our State of Software Security Volume 11, a scan of 130,000 applications found that nearly 68% of apps had a security flaw that fell into the OWASP Top 10. Vulnerable and Outdated Components, previously known as “Using Components with Known Vulnerabilities,” includes vulnerabilities resulting from unsupported or outdated software. Anyone who builds or uses an application without knowing its internal components, their versions, and whether they are updated, is exposed to this category of vulnerabilities. An injection vulnerability in a web application allows attackers to send hostile data to an interpreter, causing that data to be compiled and executed on the server.

Insecure Design

It’s a security flaw in an application that can be abused to redirect users to a malicious site. Although the OWASP Top 10 vulnerabilities are the ones that do the most harm and are most widespread, there are other vulnerabilities that hackers can exploit when attacking a website. Two other common security issues that should not be neglected are open redirects and excessive data exposure.

A multi-factor authentication scheme can be a password, pin or fingerprint. The number of cyber security cases reported in the country has increased OWASP Lessons three times in the last year. Overall, there were 1.16 million cases reported in 2020, compared to the reported 55,000 cases in 2017.

A01:2021—Broken Access Control

Most breach studies show time to detect a breach is over 200 days, typically detected by external parties rather than internal processes or monitoring. Components, such as libraries, frameworks, and other software modules, run with the same privileges as the application. If a vulnerable component is exploited, such an attack can facilitate serious data loss or server takeover. Applications and APIs using components with known vulnerabilities may undermine application defenses and enable various attacks and impacts.

When there are failures in these capabilities, your company’s ability to detect and respond to application breaches becomes severely compromised. To mitigate, use open source or proprietary tools to correlate logs, implement monitoring and alerting, and create an incident recovery and response strategy using established guidelines, such as NIST r2. To trace out the threats, try to answer the question, “what can go wrong here? ” The STRIDE model is a good place to brainstorm because it focuses on important types of application security threats and controls for preventing them.

Components with Known Vulnerabilities

Access controls are critical for securing applications against unauthorized access to data and resources. Broken access controls can lead to data compromise, obtaining permissions beyond what’s intended for standard users, or account takeover attacks where outsiders hijack user accounts and initiate fraudulent transactions. The Open Web Application Security Project is a nonprofit foundation that aims to improve software security by publishing industry standards, articles, tools, and documents. An example of the kind of tools it provides is the OWASP Risk Assessment Framework, which combines static application security testing and risk assessment tools. Insufficient logging and monitoring flaws can be introduced when attack vectors or application misbehavior is not well understood or best practices of monitoring for indicators of compromise are not followed.

While the OWASP Top Ten is a useful document for improving web application security, it is not the be-all and end-all. There is a strong focus on securing the server-side, but many of today’s attacks focus on the client-side. At a high level, one of the most important mitigation tips is to mandate the use of threat modeling for software development teams. Threat modeling should use the structure and data flow inherent to a specific web app to trace out the key technical threats that could exploit the system.
