CVE-2019-8151 in Magento
Summary
by MITRE
A remote code execution vulnerability exists in Magento 2.2 prior to 2.2.10, Magento 2.3 prior to 2.3.3 or 2.3.2-p1. An authenticated user with admin privileges to manipulate shippment settings can execute arbitrary code through server-side request forgery due to unsafe handling of a carrier gateway.

This vulnerability represents a critical remote code execution flaw in Magento e-commerce platforms that affects versions prior to specific patch releases. The vulnerability stems from insecure handling of carrier gateway configurations within the shipment management system, creating a server-side request forgery vector that allows authenticated administrators to execute arbitrary code on the affected system. The flaw specifically impacts Magento 2.2 versions before 2.2.10, Magento 2.3 versions before 2.3.3, and 2.3.2-p1 releases, making it a widespread issue across multiple platform versions.
The technical exploitation occurs through an authenticated admin user who can manipulate shipment settings to inject malicious payloads into carrier gateway configurations. This unsafe handling of external inputs allows attackers to bypass normal security controls and execute commands on the server hosting the Magento application. The vulnerability leverages the legitimate functionality of shipment carrier integrations to deliver malicious payloads, making it particularly dangerous as it operates within normal administrative workflows. This type of vulnerability aligns with CWE-918 Server-Side Request Forgery, which specifically addresses insecure interactions with external systems where user-controllable inputs are processed without proper validation.
The operational impact of this vulnerability is severe as it provides attackers with complete administrative control over the affected Magento system. Once exploited, adversaries can access sensitive customer data, modify product catalogs, manipulate orders, and potentially use the compromised system as a pivot point for further attacks within the network. The vulnerability's authentication requirement means that attackers must first obtain administrative credentials, but this does not significantly mitigate the risk given that many organizations store administrative credentials in less secure configurations or may have compromised accounts through other attack vectors. This vulnerability maps to several ATT&CK techniques including privilege escalation through valid accounts and execution through legitimate system processes.
Organizations should immediately implement patch management procedures to upgrade to the affected versions mentioned in the advisory, specifically Magento 2.2.10, 2.3.3, or 2.3.2-p1 releases. Additional mitigations include implementing network segmentation to isolate administrative functions, monitoring for unusual shipment configuration changes, and enforcing strict access controls for administrative accounts. Security teams should also consider implementing web application firewalls to detect and block suspicious requests related to carrier gateway configurations. The vulnerability highlights the importance of validating external inputs and implementing proper access controls for administrative functions within e-commerce platforms, as the flaw demonstrates how legitimate system features can be abused when proper security controls are not in place.
