Adobe Commerce, also known as Magento, is widely used for building and managing e-commerce websites. It is a popular choice among businesses of all sizes for its flexibility and robust feature set. Merchants and developers use it to create customized online stores. The platform offers a wide range of plugins and integrations, making it a versatile solution for online retail. However, like any software, it is susceptible to vulnerabilities.
The vulnerability in Adobe Commerce & Magento involves an XML External Entity (XXE) flaw. This vulnerability occurs due to improper restriction of XML entities, which can allow an attacker to execute arbitrary code. The flaw could lead to severe consequences, including data theft and server compromise. This is particularly critical as it can be exploited remotely without requiring authentication.
The XXE vulnerability in Adobe Commerce & Magento is triggered when an XML file is processed with external entity references. Specifically, the vulnerable endpoint is the /rest/V1/guest-carts/1/estimate-shipping-methods API, where the sourceData parameter in the request body can be manipulated to include a malicious URL. This URL can point to an external XML file, which when processed, allows the attacker to execute arbitrary commands on the server. The vulnerability is present due to improper validation and handling of XML input.
Exploitation of this XXE vulnerability could lead to severe consequences such as remote code execution on the server, unauthorized access to sensitive data, and potential control of the affected system. Attackers could leverage this to steal customer data, modify transactions, or disrupt the e-commerce platform, leading to financial loss and reputational damage for the affected business.
