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) attack. 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: An attacker identifies a web application using Ariadne Component Library version 2.x or earlier.
Step 2: Crafting the Malicious URL: The attacker crafts a malicious URL, potentially targeting an internal resource (e.g., http://localhost:8080/admin) or an external server controlled by the attacker.
Step 3: Injecting the URL: The attacker injects the malicious URL into a parameter that the vulnerable application uses to construct an HTTP request. This could be a URL field, a configuration setting, or a user-provided input that the library processes.
Step 4: SSRF Execution: The vulnerable application, using the Ariadne Component Library, processes the attacker-controlled URL without proper validation. It then makes an HTTP request to the attacker-specified destination.
Step 5: Impact: The server makes the request, potentially revealing internal information, accessing restricted resources, or allowing the attacker to interact with other internal services. The attacker can then use the response to gather information or trigger further attacks.
The vulnerability lies within the src/url/Url.php file of the Ariadne Component Library. The root cause is likely a lack of proper input validation and sanitization when handling URLs. Specifically, the library likely accepts user-controlled input for constructing HTTP requests without verifying the destination. This allows an attacker to craft a malicious URL, potentially pointing to internal resources or external servers, which the vulnerable server will then access. The absence of proper checks on the URL scheme (e.g., http, https) and hostname allows for exploitation. The specific function or logic flaw is unknown, but the description indicates a failure to validate user-supplied URL parameters before making an outbound request. This could be due to improper use of functions like file_get_contents or curl without sufficient input validation.
No specific APT groups or malware families are directly linked to this vulnerability based on the provided information. However, SSRF vulnerabilities are commonly exploited by various threat actors for reconnaissance, data exfiltration, and lateral movement within a network. This vulnerability is not listed on the CISA KEV (Known Exploited Vulnerabilities) catalog.
Monitor web server logs for unusual outbound HTTP requests, especially to internal IP addresses or unusual ports.
Analyze network traffic for suspicious HTTP requests originating from the server, looking for requests to internal services or external malicious domains.
Implement Web Application Firewalls (WAFs) with rules to detect and block SSRF attempts. Look for suspicious URL patterns or internal IP addresses in HTTP requests.
Review application code for instances where user-supplied URLs are used to make outbound requests. Look for missing or inadequate input validation.
Monitor for changes to internal configuration files or sensitive data that might indicate unauthorized access.
Upgrade the Ariadne Component Library to version 3.0 or later. This is the primary and most effective remediation.
Implement robust input validation and sanitization for all user-supplied URLs. Ensure that URLs are properly validated before use.
Restrict the server's ability to make outbound connections. Use a firewall to limit the destinations that the server can access.
Implement a defense-in-depth strategy, including network segmentation and least privilege access controls.
Regularly scan the application for vulnerabilities using static and dynamic analysis tools.
Review and harden the server's configuration to minimize the attack surface.
