The OWASP Top 10 in 2024

The OWASP Top 10 is a list of the ten most critical security risks for web applications. It is updated periodically to reflect the evolving threat landscape. In 2024, the OWASP Top 10 includes the following:

1. Injection: Injection attacks occur when untrusted data is sent to an interpreter as part of a command or query. This can lead to attackers executing malicious code or gaining unauthorized access to data. In recent years, injection attacks have become more sophisticated and prevalent, targeting not only traditional SQL databases but also NoSQL databases, XML parsers, and other types of interpreters. Organizations must implement robust input validation and parameterized queries to mitigate the risk of injection attacks.

2. Broken Authentication: Weak authentication and session management can allow attackers to compromise user accounts, impersonate users, or gain unauthorized access to sensitive data. In 2024, with the increasing adoption of multi-factor authentication and biometric authentication methods, attackers have shifted their focus towards bypassing these mechanisms. Organizations need to ensure that their authentication mechanisms are resilient against advanced attacks, such as credential stuffing, password spraying, and session hijacking.

3. Sensitive Data Exposure: Inadequate protection of sensitive data, such as credit card numbers or passwords, can lead to their unauthorized disclosure, resulting in identity theft or financial loss. With the rise of data breaches and privacy regulations, organizations are under increased scrutiny to protect sensitive data. Encryption, strong access controls, and data classification are essential measures to prevent sensitive data exposure.

4. XML External Entities (XXE): XXE attacks exploit the processing of XML input that contains external entity references, which can disclose internal files, perform remote code execution, or cause denial of service. In 2024, XXE attacks have become more sophisticated, leveraging new techniques to bypass security controls. Organizations should implement strict input validation, disable external entity processing, and use secure XML parsers to mitigate the risk of XXE attacks.

5. Broken Access Control: Improperly enforced access controls can allow attackers to view, modify, or delete sensitive data or perform unauthorized actions. In 2024, the complexity of access control systems has increased due to the widespread adoption of microservices and cloud environments. Organizations must carefully design and implement access control mechanisms, ensuring that they are robust, granular, and resistant to bypass techniques.

6. Security Misconfiguration: Insecure default configurations, incomplete or outdated patches, and misconfigured security settings can expose vulnerabilities that attackers can exploit. In 2024, the complexity of modern web applications and infrastructure has made security misconfigurations more common. Organizations should establish secure configuration baselines, automate configuration management, and regularly conduct security assessments to identify and remediate misconfigurations.

7. Cross-Site Scripting (XSS): XSS vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users, potentially leading to session hijacking, defacement of websites, or theft of sensitive information. In 2024, the impact of XSS attacks has increased with the growing complexity of web applications and the widespread use of client-side frameworks. Organizations should implement output encoding, strict content security policies, and vulnerability scanning tools to detect and mitigate XSS vulnerabilities.

8. Insecure Deserialization: Insecure deserialization can result in remote code execution, replay attacks, or privilege escalation. In 2024, the prevalence of insecure deserialization vulnerabilities has increased due to the popularity of deserialization frameworks and libraries. Organizations should validate and sanitize serialized data, implement secure deserialization practices, and monitor for any suspicious deserialization activities.
