A vulnerability was found in Ariadne Component Library up to 2.x. It has been classified as critical. Affected is an unknown function of the file src/url/Url.php. The manipulation leads to server-side request forgery. Upgrading to version 3.0 is able to address this issue. It is recommended to upgrade the affected component. The identifier of this vulnerability is VDB-217140.
Ariadne Component Library versions up to 2.x are vulnerable to a critical server-side request forgery (SSRF). This allows attackers to make unauthorized requests from the vulnerable server, potentially leading to data exfiltration, internal network reconnaissance, and remote code execution. Immediate patching to version 3.0 is crucial to mitigate this risk.
Step 1: Payload Delivery: The attacker identifies a web application using Ariadne Component Library version 2.x or below.
Step 2: Crafting the Malicious URL: The attacker crafts a malicious URL, designed to exploit the SSRF vulnerability. This URL could point to an internal resource (e.g., http://localhost:8080/sensitive_data) or an external server controlled by the attacker.
Step 3: Triggering the Request: The attacker provides the malicious URL as input to a function within the vulnerable application that uses the Url.php file to make requests. This input might be through a form field, API parameter, or other user-controllable input.
Step 4: Server-Side Request: The vulnerable application, using the Ariadne library, processes the attacker-provided URL and makes a request to the specified target. Because of the vulnerability, the application does not properly validate or sanitize the URL.
Step 5: Data Exfiltration/Exploitation: Depending on the target of the request, the attacker can achieve various objectives. If the target is an internal resource, the attacker might be able to access sensitive data, bypass authentication, or gain unauthorized access. If the target is an external server, the attacker can use the vulnerable server as a proxy to perform other malicious activities.
The vulnerability lies within the src/url/Url.php file of the Ariadne Component Library. The root cause is likely improper input validation or sanitization of user-supplied data used to construct URLs. Specifically, the library likely accepts a user-controlled URL, which is then used in a server-side request without adequate checks. This allows an attacker to craft a malicious URL, potentially pointing to internal resources (e.g., http://localhost:8080/admin) or external malicious servers. The lack of proper validation allows the attacker to bypass security controls and make requests on behalf of the vulnerable server. This could lead to information disclosure, unauthorized access to internal services, or even remote code execution if the SSRF is combined with other vulnerabilities.
