CVE-2024-0404

Comprehensive Technical Analysis of CVE-2024-0404

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2024-0404

Description: The vulnerability in question is a mass assignment flaw in the /api/invite/:code endpoint of the mintplex-labs/anything-llm repository. This vulnerability allows an attacker to create high-privileged accounts by intercepting and modifying the HTTP request during the account creation process via an invitation link. Specifically, the attacker can add a role property with an admin value, thereby gaining administrative access.

CVSS Score: 9.1

Severity Evaluation: The CVSS score of 9.1 indicates a critical vulnerability. This high score is due to the potential for unauthorized administrative access, which can lead to significant security breaches and data compromise.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

1. Interception of HTTP Requests: An attacker can intercept the HTTP request sent during the account creation process.
2. Modification of Request Parameters: The attacker can modify the request to include a role property with an admin value.
3. Exploitation of Mass Assignment: The lack of property allowlisting and blocklisting allows the attacker to assign administrative privileges to the newly created account.

Exploitation Methods:

1. Man-in-the-Middle (MitM) Attack: An attacker can perform a MitM attack to intercept and modify the HTTP request.
2. Direct Request Manipulation: If the attacker has access to the invitation link, they can directly manipulate the request parameters using tools like Burp Suite or OWASP ZAP.

3. Affected Systems and Software Versions

Affected Systems:

• Any system running the mintplex-labs/anything-llm repository with the vulnerable /api/invite/:code endpoint.

Software Versions:

• The specific versions affected are not mentioned, but it is implied that any version prior to the patch commit 8cd3a92c660b202655d99bee90b2864694c99946 is vulnerable.

4. Recommended Mitigation Strategies

Immediate Mitigation:

1. Apply the Patch: Ensure that the system is updated to include the patch commit 8cd3a92c660b202655d99bee90b2864694c99946.
2. Input Validation: Implement strict input validation and sanitization for all request parameters.
3. Property Allowlisting: Use property allowlisting to restrict the properties that can be set during account creation.
4. Role-Based Access Control (RBAC): Enforce RBAC to ensure that only authorized users can perform administrative actions.

Long-Term Mitigation:

1. Regular Security Audits: Conduct regular security audits and code reviews to identify and mitigate similar vulnerabilities.
2. Security Training: Provide security training for developers to understand and avoid common vulnerabilities like mass assignment.
3. Monitoring and Logging: Implement robust monitoring and logging to detect and respond to suspicious activities.

5. Impact on Cybersecurity Landscape

Immediate Impact:
