How the OWASP Top 10 Works
The OWASP Top 10 is based on extensive research and data collected from various security professionals, vulnerability databases, and community surveys. Each risk in the list is described in detail, including its potential impact, examples of how it can be exploited, and recommendations for mitigation.
This is not just a list; it’s an awareness document designed to educate developers and organizations about the most pressing security risks. Incorporating the Open Web Application Security Project Top 10 into development processes helps minimize vulnerabilities and enhance the overall security posture of web applications.
The Latest OWASP Top 10 Risks
The most recent OWASP Top 10, updated in 2021, includes the following risks:
1. Broken Access Control:
This risk occurs when applications fail to enforce proper restrictions on what authenticated users are allowed to do. This can result in unauthorized actions, such as viewing sensitive files, modifying data, or accessing administrative functions. Examples include bypassing access control checks by manipulating URLs, using custom HTTP headers, or modifying HTML content.
2. Cryptographic Failures:
Previously known as “Sensitive Data Exposure,” this category highlights issues related to cryptography, including weak encryption algorithms, poor key management practices, and improper handling of cryptographic keys. Inadequate cryptographic protections can lead to the exposure of sensitive data, such as passwords, credit card numbers, and personal information.
3. Injection:
Untrusted data is supplied to an interpreter as part of a command or query, which can lead to injection vulnerabilities such as OS, SQL, NoSQL, and LDAP injection. This allows attackers to execute unintended commands or access data without proper authorization. Common injection vulnerabilities are caused by improper input validation and escaping.
4. Insecure Design:
This category emphasizes the importance of incorporating secure design principles from the early stages of development. Insecure design flaws arise when security is not considered during the architecture and design phase, leading to vulnerabilities that are difficult to mitigate later. Examples include a lack of threat modelling, insufficient security controls, and inadequate design reviews.
5. Security Misconfiguration:
Security misconfiguration involves incorrect configuration of security settings, leaving applications vulnerable to attacks. This can include default settings, incomplete or ad-hoc configurations, open cloud storage, misconfigured HTTP headers, and verbose error messages that reveal too much information.
6. Vulnerable and Outdated Components:
Using outdated or vulnerable components, such as libraries, frameworks, and other software modules, can expose applications to known security issues. This risk highlights the importance of keeping components up-to-date and removing unnecessary dependencies. Common issues include using components with known vulnerabilities or failing to update components when security patches are released.
7. Identification and Authentication Failures:
Unauthorized access may result from vulnerabilities in authentication systems. This includes weaknesses in session management, improper implementation of authentication controls, and the use of weak or default passwords. Strong authentication mechanisms, such as multi-factor authentication and secure session management practices, are essential to mitigate these risks.
8. Software and Data Integrity Failures:
This category focuses on ensuring the integrity of software and data. Issues can arise from unauthorized code changes, insecure CI/CD pipelines, and lack of code signing. Ensuring software and data integrity involves protecting against unauthorized alterations and ensuring that code and data are not tampered with during development, deployment, and execution.
9. Security Logging and Monitoring Failures:
The identification and handling of security issues may be delayed by inadequate recording and observation. Proper logging mechanisms should be in place to capture critical security events, and monitoring systems should be configured to alert administrators to potential security breaches. Without adequate logging and monitoring, attacks can go undetected for long periods, increasing the damage caused.
10. Server-Side Request Forgery (SSRF):
When a hacker can manipulate the server to send malicious requests on their behalf, this is known as SSRF. This can lead to the exposure of internal systems and services, data exfiltration, and further compromise. SSRF vulnerabilities typically arise from insufficient validation and sanitization of user-supplied URLs, allowing attackers to manipulate server-side requests.
