CVE-2017-6018 in SpaceStation
Summary
by MITRE
An open redirect issue was discovered in B. Braun Medical SpaceCom module, which is integrated into the SpaceStation docking station: SpaceStation with SpaceCom module (integrated as part number 8713142U), software versions prior to Version 012U000040, and SpaceStation (part number 8713140U) with installed SpaceCom module (part number 8713160U), software versions prior to Version 012U000040. The web server of the affected product accepts untrusted input which could allow attackers to redirect the request to an unintended URL contained within untrusted input.

The CVE-2017-6018 vulnerability represents a critical open redirect flaw in B. Braun Medical's SpaceCom module, a component integrated into medical docking stations used in healthcare environments. This vulnerability specifically affects SpaceStation docking stations with integrated SpaceCom modules, where the affected hardware includes part numbers 8713142U and 8713140U with installed SpaceCom modules part number 8713160U. The issue manifests in software versions prior to 012U000040, creating a significant security risk within medical device ecosystems where patient data and critical medical operations are at stake. The vulnerability falls under CWE-601 which specifically addresses open redirect vulnerabilities, making it a well-documented weakness in web application security that has been consistently identified across various platforms and industries.
The technical flaw resides in the web server implementation of the affected SpaceCom module, which fails to properly validate and sanitize user input before processing redirect requests. This allows attackers to inject malicious URLs into redirect parameters, potentially leading to unauthorized redirection of users to phishing sites or malicious domains. The vulnerability exploits the fundamental principle that web applications should never trust user-provided input and should always validate all external inputs before using them in redirect operations. The flaw essentially permits attackers to manipulate the web server's redirect functionality by providing untrusted input that contains malicious URLs, bypassing normal security controls that would typically prevent such unauthorized redirects.
The operational impact of this vulnerability extends beyond typical web application security concerns due to the medical environment in which these devices operate. Healthcare systems are particularly vulnerable to such attacks as they often contain sensitive patient data and critical operational systems that could be compromised through successful redirection attacks. Attackers could potentially redirect users to malicious sites that appear legitimate, attempting to harvest credentials or deploy malware within the medical network. This vulnerability directly impacts the integrity of the device's web interface and could compromise the overall security posture of medical facilities that rely on these docking stations for device management and communication. The attack surface is particularly concerning in healthcare environments where network segmentation and security controls may be less robust compared to other enterprise sectors.
Mitigation strategies for this vulnerability should include immediate software updates to versions 012U000040 or later, which would contain the necessary patches to address the open redirect flaw. Organizations should also implement network-level controls to monitor and restrict outbound traffic from medical devices, particularly to prevent unauthorized redirects to external domains. Security teams should conduct thorough network assessments to identify any instances of the vulnerable software and ensure proper patch management procedures are in place. The remediation process should follow standard security protocols including vulnerability scanning, risk assessment, and coordinated patch deployment. Additionally, organizations should consider implementing web application firewalls and input validation controls to prevent similar issues in other applications and systems within their medical device ecosystem. This vulnerability demonstrates the critical importance of maintaining up-to-date medical device software and the necessity of robust security controls in healthcare environments where device integrity directly impacts patient safety and data protection.
