CVE-2024-22408 in Shopware
Summary
by MITRE • 01/17/2024
Shopware is an open headless commerce platform. The implemented Flow Builder functionality in the Shopware application does not adequately validate the URL used when creating the “call webhook” action. This enables malicious users to perform web requests to internal hosts. This issue has been fixed in the Commercial Plugin release 6.5.7.4 or with the Security Plugin. For installations with Shopware 6.4 the Security plugin is recommended to be installed and up to date. For older versions of 6.4 and 6.5 corresponding security measures are also available via a plugin. For the full range of functions, we recommend updating to the latest Shopware version.

The vulnerability identified as CVE-2024-22408 affects Shopware, a popular open headless commerce platform that enables businesses to build and manage digital commerce experiences. This security flaw resides within the Flow Builder functionality, which serves as a workflow automation tool that allows administrators to create automated business processes. The specific weakness manifests in how the platform handles URL validation when configuring the "call webhook" action, creating a potential pathway for unauthorized network access that could be exploited by malicious actors.
The technical flaw stems from insufficient input validation mechanisms within the Flow Builder's webhook implementation. When users configure webhook actions within the platform's workflow system, the application fails to properly validate the target URLs, particularly those pointing to internal network resources. This validation gap allows attackers to craft malicious webhook configurations that can initiate HTTP requests to internal hosts that would normally be protected from external access. The vulnerability essentially creates a bypass mechanism that enables internal network reconnaissance and potential exploitation of internal services that should remain isolated from external threats. This weakness directly maps to CWE-20, which addresses improper input validation, and represents a classic case of insecure direct object reference where the system fails to verify the legitimacy of requested resources.
The operational impact of this vulnerability is significant for organizations using Shopware implementations, particularly those with complex network architectures or sensitive internal systems. Attackers could leverage this flaw to perform internal network scanning, potentially discovering and targeting internal services, databases, or other systems that should remain hidden from external access. The vulnerability creates an attack surface that could enable further exploitation, including potential data exfiltration, service disruption, or even lateral movement within the network infrastructure. Organizations relying on Shopware for their commerce operations face increased risk of unauthorized access to their internal systems, which could compromise sensitive customer data, business operations, and overall network security posture.
Security mitigations for this vulnerability are well-defined and primarily involve updating to patched versions of the Shopware platform. The official fix has been incorporated into the Commercial Plugin release 6.5.7.4 and through the dedicated Security Plugin. For users operating on Shopware 6.4 installations, the Security Plugin serves as a recommended solution to address the vulnerability while maintaining compatibility with existing systems. Organizations running older versions of Shopware 6.4 and 6.5 should install the appropriate security patches through the plugin system to protect their environments. The recommended approach aligns with ATT&CK framework tactic TA0011 - Command and Control, where adversaries establish covert communication channels to maintain access to compromised systems. The vulnerability represents a critical security gap that organizations must address promptly to prevent potential exploitation and maintain the integrity of their commerce platform infrastructure.
