CVE-2008-7139 in Eye-Fi Manager
Summary
by MITRE
Multiple cross-site request forgery (CSRF) vulnerabilities in WS-Proxy in Eye-Fi 1.1.2 allow remote attackers to hijack the authentication of users for requests that modify configuration via a SOAPAction parameter of (1) urn:SetOptions for autostart, (2) urn:SetDesktopSync for file upload, or (3) urn:SetFolderConfig for file download location or modification of authentication credentials; and (4) urn:AddNetwork for adding an arbitrary Service Set Identifier (SSID) to hijack the image upload.

The CVE-2008-7139 vulnerability represents a critical cross-site request forgery flaw in Eye-Fi's WS-Proxy component version 1.1.2, which operates as a web service proxy for wireless file transfer capabilities. This vulnerability exists within the authentication and authorization mechanisms of the Eye-Fi device's web interface, creating a significant security risk for users who rely on the device for automated file uploads and configuration management. The flaw allows remote attackers to exploit the SOAP-based web service interface without proper authentication, potentially compromising the entire file transfer ecosystem that Eye-Fi devices provide to consumers and enterprise users.
The technical exploitation of this vulnerability occurs through manipulation of the SOAPAction parameter within HTTP requests sent to the WS-Proxy service. Attackers can craft malicious requests that target four specific SOAP actions, each corresponding to different configuration modification capabilities. The first action urn:SetOptions enables attackers to modify the device's autostart behavior, potentially causing unauthorized automatic file uploads. The second action urn:SetDesktopSync allows manipulation of file upload configurations, while urn:SetFolderConfig provides access to modify file download locations or authentication credentials. The fourth action urn:AddNetwork enables attackers to add arbitrary SSIDs, which can be used to hijack image upload processes by redirecting the device to malicious access points. This multi-vector attack surface demonstrates the comprehensive nature of the CSRF vulnerability in the device's web service implementation.
The operational impact of this vulnerability extends beyond simple unauthorized configuration changes, as it enables complete hijacking of the Eye-Fi device's functionality and potentially compromises user data security. When an attacker successfully exploits these CSRF vulnerabilities, they can gain unauthorized access to the device's file transfer capabilities and modify critical configuration parameters without user knowledge or consent. The authentication bypass allows attackers to manipulate the device's behavior to automatically upload files to attacker-controlled servers, potentially exposing sensitive information stored on the device. The ability to modify authentication credentials through these vulnerabilities creates a persistent threat where attackers can maintain long-term access to the device and its file transfer capabilities, making this vulnerability particularly dangerous for enterprise deployments where Eye-Fi devices might be used for sensitive data transfer.
The vulnerability aligns with CWE-352, which specifically addresses Cross-Site Request Forgery weaknesses in web applications, and maps to several ATT&CK techniques including T1566 for credential access through social engineering and T1071 for application layer protocol usage. The attack surface is particularly concerning because it leverages the device's legitimate web service interfaces to perform unauthorized operations, making detection difficult for network monitoring systems. The implementation flaw exists in the WS-Proxy component's failure to properly validate request sources and implement proper anti-CSRF mechanisms such as token-based validation or referer header checks. Security professionals should note that this vulnerability demonstrates the importance of implementing robust authentication verification mechanisms in web services, particularly those that control device configuration and file transfer operations. The lack of proper CSRF protection in the SOAP-based web service interface creates a persistent security risk that can be exploited by attackers with minimal technical expertise, highlighting the need for comprehensive security testing of web service implementations in IoT devices.
Organizations and users should immediately disable or upgrade affected Eye-Fi devices and implement network monitoring to detect unauthorized access attempts. The vulnerability requires patching of the WS-Proxy component and implementation of proper CSRF protection measures including anti-CSRF tokens and request origin validation. Security controls should include network segmentation to limit access to the device's web service interface and regular security audits of IoT device configurations. The vulnerability serves as a reminder of the critical importance of proper authentication verification in web services and the potential consequences of inadequate CSRF protection in enterprise and consumer IoT deployments.
