CVE-2024-0403 in Recipes
Summary
by MITRE • 03/01/2024
Recipes version 1.5.10 allows arbitrary HTTP requests to be made
through the server. This is possible because the application is
vulnerable to SSRF.

The vulnerability identified as CVE-2024-0403 affects Recipes version 1.5.10 and represents a critical server-side request forgery flaw that enables attackers to execute arbitrary HTTP requests through the affected server. This vulnerability stems from insufficient input validation and improper handling of external resource requests within the application's architecture, creating a pathway for malicious actors to bypass normal access controls and potentially access internal systems or sensitive data. The SSRF vulnerability specifically allows an attacker to manipulate the application's request handling mechanism to target internal network resources that would otherwise be protected by firewalls or network segmentation.
The technical implementation of this vulnerability occurs when the application processes user-supplied input that is used to construct HTTP requests without adequate sanitization or validation. This flaw typically manifests when the application accepts parameters that define target URLs or endpoints and directly uses these inputs to establish connections to external services. Attackers can exploit this by crafting malicious requests that include internal IP addresses, localhost references, or other network targets that should not be accessible through the public interface. The vulnerability is particularly dangerous because it can be leveraged to enumerate internal services, access administrative interfaces, or even exfiltrate data from behind network firewalls. According to CWE classification, this represents a variant of CWE-918 Server-Side Request Forgery, which specifically addresses the issue of unvalidated requests being sent from a server to other internal or external systems. The ATT&CK framework categorizes this under T1071.004 Application Layer Protocol: DNS, where attackers can use SSRF to bypass network restrictions and gain access to internal resources that are not directly exposed to the internet.
The operational impact of CVE-2024-0403 extends beyond simple data theft, as it can enable attackers to perform reconnaissance activities, escalate privileges, and potentially compromise entire internal network infrastructures. An attacker could use this vulnerability to scan internal networks for additional vulnerable systems, access databases or administrative interfaces that are normally protected, or even establish persistent access through the compromised server. The vulnerability affects the application's trust model, as it allows external entities to make requests that the application would normally only make for legitimate purposes. Organizations running affected versions of Recipes software face significant risk of unauthorized access to internal systems, potential data breaches, and the possibility of using the compromised server as a pivot point for further attacks. The impact is particularly severe in environments where the application server has access to sensitive internal resources or where network segmentation is not properly enforced, as the vulnerability can be exploited to bypass traditional security controls and gain access to systems that should remain isolated from external networks.
Mitigation strategies for CVE-2024-0403 should focus on implementing robust input validation and request filtering mechanisms within the application. Organizations should immediately upgrade to the latest version of Recipes software where this vulnerability has been patched and properly addressed. Network-level protections such as firewall rules and proxy configurations should be implemented to restrict outbound connections from the affected server and prevent it from accessing internal resources without proper authorization. The application should be configured to use allowlists of approved domains or IP addresses for outbound requests, and all user-supplied inputs that could influence HTTP requests should be strictly validated and sanitized. Additionally, implementing proper logging and monitoring of HTTP requests can help detect and respond to exploitation attempts. Security teams should also consider implementing network segmentation and access controls to limit the potential impact of successful exploitation, ensuring that even if an attacker gains access through this vulnerability, they cannot easily move laterally within the network infrastructure. Regular security assessments and penetration testing should be conducted to identify and remediate similar vulnerabilities in other applications within the organization's attack surface.
