Magento Information Disclosure Scanner

The Magento software is utilized by online retailers and e-commerce businesses to create, manage, and enhance their digital storefronts. It offers extensive customizability and third-party integrations, which makes it a popular choice for enterprises looking to provide a scalable online shopping experience. The software plays a crucial role in managing product catalogs, processing payments, and maintaining customer databases. With its comprehensive features, Magento is widely used across various industries, from small businesses to large multinational organizations, to enhance their digital commerce capabilities. Its flexible architecture supports various extensions and plugins, allowing companies to personalize their customers' experiences. Overall, Magento provides a robust platform to facilitate online sales and customer engagement.

Information disclosure vulnerabilities occur when an application unintentionally exposes sensitive information to unauthorized parties. This vulnerability allows attackers to gain insights into the underlying software implementation by accessing verbose error messages or internal paths. In the context of the Magento Downloader component, it can lead to exposing parts of the internal file system. This vulnerability does not change the execution flow of the program but may disclose valuable information that can assist in further attacks. Such vulnerabilities are often ranked low in severity individually but can contribute to more severe exploitation when combined with other vulnerabilities.

The Magento Downloader's exposure to full path disclosure happens through specific files in the downloader/lib/Mage/ directory. The vulnerable endpoints may include direct access to files like Nomedia.php, Tar.php, Gz.php, and Bz.php. The access to these files results in the displaying of internal file paths within error messages, revealing critical directory information. The vulnerability is triggered when an unauthenticated request is made directly to these endpoints and the server responds with a status code of 200 along with certain error strings visible in the body, confirming the presence of this issue. Ensuring these endpoints are not exposed can help mitigate such risks.

When exploited, information disclosure vulnerabilities like the one found in Magento can be leveraged by attackers to map out the directory structure of the server and gain insights into its configuration. This could facilitate further exploitation, such as identifying additional vulnerabilities or preparing for more sophisticated attacks. It can aid in planning subsequent steps in an attack chain, making the overall system more susceptible to breaches. While the direct impact may seem nominal, the indirect implications on security can be significant.
