CVE-2026-42281 Scanner

The MagicMirror software is a widely used platform for displaying customizable data and information on mirrors, often utilized in smart homes and retail environments. Primarily designed for developers and tech enthusiasts, it allows for the integration of various modules and extensions to display customized information such as weather updates, news, and calendars. Developers leverage MagicMirror for its ease of use and flexibility in configuring display modules. It offers an open-source platform, supported by a community that contributes to its feature set and performance enhancements. Being a node-based application, it serves both hobbyists and commercial users seeking to create interactive digital displays. Organizations use MagicMirror to engage customers and visitors by providing real-time information in an aesthetic way.

The server-side request forgery (SSRF) vulnerability in MagicMirror <= 2.35.0 allows attackers to induce the server to initiate requests to certain endpoints, bypassing standard authentication and control measures. SSRF enables attackers to manipulate URLs and exploit server misconfigurations to access privileged information or functionalities. This vulnerability can be exploited without user interaction, as the attacker can directly manipulate input parameters used in server-side network requests. It poses significant risks due to potential exposure of internal services or sensitive resources. The issue arises in the '/cors' endpoint, which lacks sufficient validation for incoming URLs. Attackers exploit this issue to retrieve or manipulate backend data and configurations improperly.

Technical details of this SSRF vulnerability involve the unauthorized access to the '/cors' endpoint, facilitating server requests to unintended URLs. The SSRF attack uses specific parameters within HTTP requests to target the MagicMirror application, allowing the exploitation of the internal request logic. This includes targeting localhost or internal network interfaces, often via manipulated URL query strings. Such actions can lead to requests to unauthorized locations, potentially exposing sensitive server-side configurations. Attackers often employ interactsh services to simulate these attacks and validate successful exploitation. Effective exploitation necessitates an understanding of the '/cors' logic for initiating server requests, requiring careful crafting of malicious URL parameters.

When exploited, this vulnerability may allow attackers to access sensitive information or services hosted on the internal network by leveraging the server's access capabilities. It could lead to data leaks from internal databases or expose internal network architecture by circumventing traditional network security barriers. Moreover, the possibility exists to manipulate or access cloud services through misconfigured network paths. The effects are further compounded if attackers gain the ability to alter configurations or access sensitive environments via exposed endpoints or metadata services. The exploitation's potential impact includes broader network compromise due to unauthorized data exposure and manipulation abilities.
