IDOR vulnerability

Vulnerability Assessment as a Service (VAaaS)

Tests systems and applications for vulnerabilities to address weaknesses.

What is IDOR Vulnerability?

IDOR stands for “Insecure Direct Object References” and it is a type of vulnerability that occurs when an application references an object (such as a file or database record) using user-supplied input, without proper validation or authentication. This can allow an attacker to access or manipulate sensitive information or perform unauthorized actions. IDOR vulnerabilities can be found in various types of applications, such as web, mobile, and desktop applications.

IDOR vulnerabilities can appear in different types of applications, including:

Web applications: IDOR vulnerabilities in web applications can occur when user input is used to access sensitive information or perform actions without proper validation or authentication. For example, an attacker could change a parameter in a URL to access a different user’s account or manipulate data in a database.

Mobile applications: IDOR vulnerabilities in mobile applications can occur when the app uses user-supplied input to access sensitive information or perform actions without proper validation or authentication. For example, an attacker could use a tool to intercept and modify network traffic to access sensitive data or perform unauthorized actions.

Desktop applications: IDOR vulnerabilities in desktop applications can occur when the application uses user-supplied input to access sensitive information or perform actions without proper validation or authentication. For example, an attacker could use a tool to intercept and modify network traffic to access sensitive data or perform unauthorized actions.

This type of vulnerability can occur in any type of application that uses user-supplied input to access sensitive information or perform actions without proper validation or authentication.

Example of vulnerable code on different programming languages

Here are a few examples of IDOR vulnerabilities in different programming languages:

PHP:

				
					<?php
$user_id = $_GET['user_id'];
$query = "SELECT * FROM users WHERE id = $user_id";
$result = mysqli_query($link, $query);
// ...
				
			

The script is using the user-supplied $_GET[ ‘user_id’ ] variable to construct a database query without proper validation or authentication. An attacker could modify the user_id parameter in the URL to access or manipulate sensitive information.

Java:

				
					String userId = request.getParameter("user_id");
User user = userService.getUser(userId);
// ...

				
			

The script is using the user-supplied ‘request.getParameter( “user_id” )’ to get user data from the service without proper validation or authentication. An attacker could modify the ‘user_id’ parameter in the request to access or manipulate sensitive information.

JavaScript:

				
					String userId = request.getParameter("user_id");
User user = userService.getUser(userId);
// ...

				
			

The script is using the user-supplied ‘window.location.hash’ value to access user data without proper validation or authentication. An attacker could modify the user_id parameter in the URL hash to access or manipulate sensitive information.

Python:

				
					user_id = request.args.get("user_id")
user = User.query.filter_by(id=user_id).first()
				
			

The script is using the user-supplied request.args.get( “user_id” ) variable to construct a database query without proper validation or authentication. An attacker could modify the user_id parameter in the URL to access or manipulate sensitive information.

As with the other examples, it’s important to validate and authenticate the user-supplied data before using it to access or manipulate sensitive information or perform actions.

Also recommended to use libraries such as Flask-SQLAlchemy or Django ORM which have built-in protection against SQL injection and similar vulnerabilities, that’s why it’s important to use libraries and frameworks that provide security features and follow best practices when developing the application.

Examples of exploitation IDOR vulnerability

There are several ways in which an IDOR vulnerability can be exploited. Here are a few examples:

1. Data leakage: An attacker can use an IDOR vulnerability to access sensitive information, such as personal information, financial data, or confidential documents. For example, an attacker could change a parameter in a URL to access a different user’s account or manipulate data in a database. This can result in data leakage, where sensitive information is exposed to unauthorized parties.

2. Account takeover: An attacker can use an IDOR vulnerability to take over a user’s account, allowing them to perform actions as if they were the legitimate user. For example, an attacker could change a parameter in a URL to access a different user’s account and change the account’s password. This can result in the attacker gaining access to sensitive information or performing unauthorized actions.

3. Privilege escalation: An attacker can use an IDOR vulnerability to gain higher levels of access to a system. For example, an attacker could change a parameter in a URL to access a different user’s account and gain access to restricted areas of the application or sensitive information.

4. CSRF: An attacker can use an IDOR vulnerability to perform actions on a victim’s behalf. For example, an attacker could craft a link that, when clicked by the victim, would cause the victim’s browser to perform an action in the application, such as making a purchase or changing a password. This is known as Cross-Site Request Forgery (CSRF) attack.

5. Phishing: An attacker can use an IDOR vulnerability to gain sensitive information from the user. For example, an attacker could craft a link that, when clicked by the user, would redirect the user to a fake login page and steal their credentials.

These are just a few examples of how an IDOR vulnerability can be exploited. It’s important to note that the impact and severity of an IDOR vulnerability can vary depending on the specific application and the types of data and actions that are exposed.

Important to note that IDOR vulnerabilities can be discovered by manual testing, automated scanning or by exploiting known vulnerabilities in third-party libraries and frameworks. It’s also important to have an incident response plan in place to handle IDOR vulnerabilities that are discovered, and to keep software updated to prevent from exploiting known vulnerabilities.

Privilege escalation techniques on IDOR vulnerability

Privilege escalation is a technique used to gain access to resources or perform actions that are normally restricted to a user or group. There are several techniques that can be used for privilege escalation:

1. Exploiting vulnerabilities: This technique involves finding and exploiting vulnerabilities in software or systems to gain access to resources or perform actions that are normally restricted. This can include things like SQL injection, cross-site scripting (XSS), or buffer overflow vulnerabilities.

2. Social engineering: This technique involves tricking or manipulating users into providing access to resources or performing actions that are normally restricted. This can include things like phishing, baiting, or pretexting.

3. Exploiting misconfigurations: This technique involves finding and exploiting misconfigurations in software or systems to gain access to resources or perform actions that are normally restricted. This can include things like default or weak passwords, open network shares, or misconfigured permissions.

4. Using a backdoors: This technique involves using a previously installed malicious code to gain access to resources or perform actions that are normally restricted.

5. Exploiting known credentials: This technique involves using compromised or guessed credentials to gain access to resources or perform actions that are normally restricted.

6. Using tools and scripts: This technique involves using tools and scripts, such as Metasploit, to gain access to resources or perform actions that are normally restricted.

Privilege escalation attacks can be very effective, especially when combined with other techniques like social engineering or exploiting vulnerabilities. It’s also important to note that privilege escalation attacks can be difficult to detect and prevent, as they often involve exploiting legitimate access or functionality in a system. It’s essential to have a defense-in-depth security strategy in place, which includes regular vulnerability scanning, penetration testing, and incident response plans. Additionally, it’s important to keep software updated, to minimize the risk of exploiting known vulnerabilities.

General methodology and checklist for testing for IDOR vulnerabilities

Methodology for testing for IDOR vulnerabilities:

1. Identify the scope of the testing: Identify the specific application or system to be tested, as well as any relevant subdomains or third-party services that may be included in the scope.

2. Recon: Gather information about the application or system, such as the technology stack, endpoints, and parameters used. This can be done using tools such as nmap, dirb, and Burp Suite.

Also it’s important to have a comprehensive incident response plan in place to handle any vulnerabilities that are discovered, and to keep software updated to prevent from exploiting known vulnerabilities.

An incident response plan for IDOR vulnerabilities may include the following steps:

1. Identification: Identify that an incident has occurred and that it involves an IDOR vulnerability. This may be through monitoring system logs, receiving an alert from a security tool, or a customer report.

2. Containment: Contain the incident to prevent further damage or data loss. This may include disconnecting affected systems from the network, disabling compromised accounts, and shutting down services.

3. Eradication: Remove the vulnerability or malicious code that allowed the incident to occur. This may include patching systems, changing credentials, and cleaning up data.

4. Recovery: Restore systems and services to normal operation. This may include restoring backups, rebuilding systems, and testing to ensure that the vulnerability has been fully remediated.

5. Lessons learned: Conduct a post-incident review to identify lessons learned and areas for improvement. This may include evaluating the incident response plan and identifying gaps in security controls.

6. Communication: Communicate with relevant stakeholders, including customers, partners, and regulators as needed, to keep them informed of the situation and any actions taken.

7. Monitoring: Monitor systems and network for any further activity related to the incident to ensure that the vulnerability is not exploited again.

Current incident response plan is a general one, and it’s important to adjust it according to the specific requirements of your organization. It’s also important to regularly practice and test the incident response plan to ensure that it’s effective and that all personnel are familiar with it.

Average CVSS score of IDOR vulnerability

The Common Vulnerability Scoring System (CVSS) is a standardized method for assessing the severity of vulnerabilities. It is used to assign a numerical score to a vulnerability based on its characteristics, such as its impact on confidentiality, integrity, and availability, as well as its exploitability.

The CVSS score for an IDOR vulnerability can vary depending on the specific characteristics of the vulnerability and the context in which it is being exploited. However, IDOR vulnerabilities are generally considered to be medium to high severity.

IDOR vulnerabilities typically receive a CVSS score between 6.0 and 8.0, which is considered as medium to high risk. This is because IDOR vulnerabilities allow an attacker to gain unauthorized access to sensitive information, which can lead to data breaches, financial losses, and reputational damage.

The CVSS scoring system has three metrics Base, Temporal, and Environmental. The Base score reflects the intrinsic characteristics of a vulnerability, while the Temporal score reflects the maturity of the vulnerability and how easy it is to exploit. The Environmental score reflects the characteristics of the environment in which the vulnerability is found.

An IDOR vulnerability that allows an attacker to easily access sensitive information without any authentication, such as by modifying a parameter in a URL, would be considered a high-severity vulnerability and receive a higher CVSS score than an IDOR vulnerability that requires an attacker to first exploit a separate vulnerability, such as SQL injection, in order to access sensitive information.

The Common Weakness Enumeration (CWE) for IDOR

The Common Weakness Enumeration (CWE) is a list of software weaknesses that can lead to security vulnerabilities. Each entry in the CWE list includes a unique identifier, a name, and a description of the weakness. CWEs are used to classify and describe the types of security vulnerabilities that can occur in software.

Here is a list of CWEs that are commonly associated with IDOR vulnerabilities:

CWE-639: Authorization Bypass through User-Controlled Key: This weakness occurs when a system allows an attacker to control an access key or token that is used to grant access to a resource. This can allow the attacker to bypass authorization checks and gain unauthorized access to the resource.

CWE-601: URL Redirection to Untrusted Site (‘Open Redirect’): This weakness occurs when a web application redirects a user to a URL that is controlled by an attacker. This can allow the attacker to phish for sensitive information or redirect the user to a malicious site.

CWE-918: Server-Side Request Forgery (SSRF): This weakness occurs when a web application makes a request to a server that is controlled by an attacker. This can allow the attacker to access sensitive information or perform actions on behalf of the web application.

CWE-919: Improper Limitation of a Pathname to a Restricted Directory (‘Path Traversal’): This weakness occurs when a web application does not properly validate user-supplied input that is used to construct a file path. This can allow an attacker to access files outside of the intended directory.

CWE-922: Improper Constraint of Operations within the Bounds of a Memory Buffer: This weakness occurs when a program does not properly validate the size of input data before it is stored in a memory buffer. This can allow an attacker to cause a buffer overflow and execute arbitrary code.

CWE-923: Improper Limitation of a Pathname to a Restricted Directory (‘Path Traversal’): This weakness is similar to CWE-919, but specifically applies to path traversal vulnerabilities in non-web contexts.

CWE-927: Improper Authorization: This weakness occurs when a system does not properly enforce authorization rules. This can allow an attacker to access resources or perform actions that they should not have access to.

CWE-928: Improper Control of Access to a Resource: This weakness occurs when a system does not properly control access to a resource. This can allow an attacker to access or modify the resource without proper authorization.

CWE-929: Improper Control of Access to a Resource Through Dynamic Resolution: This weakness is similar to CWE-928 but occurs when a system does not properly control access to a resource when the resource is dynamically resolved.

CWE-931: Improper Restriction of Operations within the Bounds of a Memory Buffer: This weakness is similar to CWE-922 but specifically applies to buffer overflow vulnerabilities in non-web contexts.

CWE-932: Improper Control of Resource Identifiers: This weakness occurs when a system does not properly control the generation or use of resource identifiers. This can allow an attacker to access or modify a resource that they should not have access to.

IDOR vulnerability exploits

There are several types of IDOR vulnerabilities and corresponding exploits that can be used to exploit them:

1. URL Tampering: An attacker changes the values in the URL parameters to access restricted resources or gain unauthorized access. This exploit is commonly used in web applications.

2. HTTP Request Smuggling: This exploit involves manipulating the way that web servers process multiple HTTP requests in order to gain unauthorized access.

3. Path Traversal: An attacker manipulates the file path in a URL to access files or directories that they should not have access to.

4. SSRF (Server-Side Request Forgery): This exploit allows an attacker to send a specially crafted request to a server to gain unauthorized access.

5. Injection Attacks: These exploits involve injecting malicious code or input into a web application to gain unauthorized access. Examples include SQL injection, command injection, and script injection.

6. DLL Injection: This exploit allows an attacker to inject malicious code into a dynamic link library (DLL) in order to gain unauthorized access.

7. File Inclusion: This exploit allows an attacker to include a file from a remote server in order to gain unauthorized access.

8. Privilege Escalation: This exploit allows an attacker to gain access to resources or privileges that they should not have access to.

9. Resource Hijacking: This exploit allows an attacker to take control of a resource, such as a file or a database, in order to gain unauthorized access.

10. Session Hijacking: This exploit allows an attacker to take control of a user’s session in order to gain unauthorized access.

This is just an examples, new exploits are discovered and created regularly.

Practicing in test for IDOR vulnerability

There are several ways to practice testing for IDOR vulnerabilities:

1. Use a web application scanner: There are several commercial and open-source web application scanners that can help you identify IDOR vulnerabilities in web applications. These scanners can automatically identify vulnerabilities and provide recommendations for how to fix them.

2. Create your own test cases: You can create your own test cases by manually manipulating the values in the URLs, headers, or other parts of a web application to see if you can access restricted resources or gain unauthorized access.

3. Use a Penetration Testing Framework: There are several penetration testing frameworks that include modules for testing for IDOR vulnerabilities such as Metasploit, Burp Suite, and OWASP ZAP.

4. Participate in a Capture the Flag (CTF) event: CTF events are competitions where participants are given a set of challenges that test their skills in identifying and exploiting vulnerabilities. Many CTF events include challenges that test for IDOR vulnerabilities.

5. Practice on vulnerable web apps: There are several intentionally vulnerable web applications that are designed for testing and training purposes, such as OWASP Juice Shop, WebGoat, and DVWA.

6. Read and practice with exploit codes: There are several resources available online that provide exploit codes for IDOR vulnerabilities, such as Exploit-DB. Reading and practicing with these exploit codes can help you understand how IDOR vulnerabilities are exploited and how to identify them.

Detecting and Preventing IDOR Vulnerabilities

Detecting and preventing IDOR vulnerabilities involves a combination of security measures, coding practices, and testing. Some of the ways to detect and prevent IDOR vulnerabilities are:

1. Input validation and sanitization: Ensure that all user inputs are validated and sanitized to prevent any malicious input from being processed by the application.

2. Access control and authorization: Implement proper access control and authorization mechanisms to ensure that only authorized users have access to sensitive resources.

3. Session management: Properly manage user sessions to prevent session hijacking and ensure that sensitive data is not disclosed.

4. Encryption: Encrypt sensitive data to ensure that it is protected from unauthorized access.

5. Logging and monitoring: Implement logging and monitoring mechanisms to detect any suspicious activity and track all access to sensitive resources.

6. Penetration testing: Regularly test the application for vulnerabilities, including IDOR vulnerabilities, using automated security testing tools and manual penetration testing.

7. Code review: Regularly review the code to ensure that all security best practices are being followed and to identify any security weaknesses.

8. Keep software updated: Regularly update the software and its components to ensure that any known vulnerabilities are patched.

By implementing these measures, organizations can reduce the risk of IDOR vulnerabilities and protect sensitive data from being accessed by unauthorized users.

Conclusion

In conclusion, IDOR (Insecure Direct Object Reference) vulnerability is a type of security vulnerability that occurs when an application exposes direct object references, such as URLs or database keys, without proper authorization checks. This vulnerability allows attackers to access restricted resources or manipulate data without proper authorization. To prevent IDOR vulnerabilities, it is important to implement proper authorization checks, validate user inputs, and restrict direct object references. Additionally, performing regular security assessments and testing can help identify and mitigate IDOR vulnerabilities in applications.
