The Latest OWASP Top 10 (2021)
The most recent iteration of the OWASP Top 10 was released in 2021, reflecting the evolving landscape of web application security. Let's dive deep into each of these vulnerabilities, understanding what they are, why they're dangerous, and how to mitigate them. The OWASP Top 10 is typically updated every few years, with the next update expected in early 2025.
1. Broken Access Control
Climbing from the fifth position in 2017 to the top spot in 2021, Broken Access Control has become the most critical web application security risk. This vulnerability occurs when users can act beyond their intended permissions, potentially leading to unauthorized information disclosure, modification, or destruction of data.
Examples of broken access control include:
- Modifying a URL parameter to access another user's account
- Bypassing access checks by modifying the web browser's state
- Elevating privileges to those of an administrator
To mitigate this risk, developers should implement robust access control mechanisms, including:
- Enforcing principle of least privilege
- Implementing proper session management
- Conducting thorough testing of access control mechanisms
2. Cryptographic Failures
Previously known as "Sensitive Data Exposure," this category emphasizes failures related to cryptography that often lead to sensitive data exposure. This risk underscores the importance of properly implementing encryption and other cryptographic practices to protect sensitive information.
Common cryptographic failures include:
- Using weak cryptographic algorithms
- Improper implementation of strong algorithms
- Inadequate key management
To address this risk:
- Use strong, up-to-date cryptographic algorithms
- Implement proper key management practices
- Encrypt all sensitive data in transit and at rest
3. Injection
Injection flaws, such as SQL, NoSQL, OS, and LDAP injection, occur when untrusted data is sent to an interpreter as part of a command or query. The attacker's hostile data can trick the interpreter into executing unintended commands or accessing data without proper authorization.
Injection attacks can lead to:
- Data theft, modification, or destruction
- Loss of data integrity
- Denial of service
- Complete system takeover
Prevention measures include:
- Using parameterized queries
- Input validation and sanitization
- Adopting Object Relational Mapping (ORM) tools
4. Insecure Design
A new addition to the OWASP Top 10, Insecure Design focuses on risks related to design and architectural flaws. This category emphasizes the need to shift left in the software development lifecycle, incorporating security by design principles from the outset.
Insecure design can manifest as:
- Missing or ineffective control design
- Business logic flaws
- Inadequate threat modeling
To improve design security:
- Implement secure development lifecycle practices
- Use threat modeling in the design phase
- Conduct regular security architecture reviews
5. Security Misconfiguration
Security misconfiguration remains a prevalent issue, often resulting from insecure default configurations, incomplete or ad hoc configurations, open cloud storage, misconfigured HTTP headers, and verbose error messages containing sensitive information.
Common misconfigurations include:
- Unnecessary features enabled or installed
- Default accounts with unchanged passwords
- Overly informative error messages
Mitigation strategies:
- Implement a repeatable hardening process
- Review and update configurations regularly
- Maintain a minimal platform without unnecessary features
6. Vulnerable and Outdated Components
Components such as libraries, frameworks, and other software modules often run with full privileges. If a vulnerable component is exploited, it can facilitate serious data loss or server takeover.
Risks associated with vulnerable components:
- Known vulnerabilities in widely used components
- Lack of support for older versions
- Difficulty in tracking component versions
To address this risk:
- Maintain an inventory of all components
- Monitor sources like CVE and NVD for vulnerabilities
- Implement a patch management process
7. Identification and Authentication Failures
Previously known as "Broken Authentication," this category includes weaknesses in session management, credential management, and other aspects of establishing and maintaining user identity.
Common failures include:
- Permitting weak passwords
- Poorly implemented multi-factor authentication
- Session fixation attacks
Best practices for robust authentication:
- Implement multi-factor authentication
- Limit or delay failed login attempts
- Use secure session management techniques
8. Software and Data Integrity Failures
This new category focuses on making assumptions related to software updates, critical data, and CI/CD pipelines without verifying integrity. It includes insecure deserialization, which can lead to remote code execution attacks.
Integrity failures can result in:
- Unauthorized code execution
- Data tampering
- Supply chain attacks
Mitigation strategies:
- Use digital signatures to verify software integrity
- Ensure libraries and dependencies are from trusted sources
- Implement integrity checks for critical data
9. Security Logging and Monitoring Failures
Insufficient logging and ineffective integration with incident response can allow attackers to further attack systems, maintain persistence, pivot to more systems, and tamper, extract, or destroy data.
Consequences of inadequate logging and monitoring:
- Delayed breach detection
- Inability to conduct proper forensic analysis
- Increased impact of successful attacks
To improve logging and monitoring:
- Implement centralized log management
- Ensure logs capture sufficient detail without including sensitive data
- Regularly review and analyze logs for suspicious activity
10. Server-Side Request Forgery (SSRF)
SSRF flaws occur when a web application is fetching a remote resource without validating the user-supplied URL. This can allow attackers to coerce the application to send a crafted request to an unexpected destination, even when protected by a firewall, VPN, or another type of network access control list (ACL).
SSRF can lead to:
- Data exfiltration
- Internal system compromise
- Lateral movement within internal networks
To prevent SSRF:
- Sanitize and validate all client-supplied input data
- Enforce the URL schema, port, and destination with a positive allow list
- Disable HTTP redirections
