CVE-2016-10580 in nodewebkit
Summary
by MITRE
nodewebkit is an installer for node-webkit. nodewebkit downloads zipped resources over HTTP, which leaves it vulnerable to MITM attacks. It may be possible to cause remote code execution (RCE) by swapping out the requested zip file with an attacker controlled zip file if the attacker is on the network or positioned in between the user and the remote server.

The vulnerability identified as CVE-2016-10580 affects nodewebkit, a tool designed to facilitate the installation of node-webkit applications. This installer operates by downloading compressed resources through unencrypted HTTP connections rather than secure HTTPS protocols. The fundamental flaw lies in the absence of cryptographic protection during the download process, creating a significant security gap that adversaries can exploit. The vulnerability is categorized under CWE-319, which specifically addresses the exposure of sensitive information through improper use of network protocols. When nodewebkit retrieves zipped resources over HTTP, it fails to implement proper certificate validation or data integrity checks, making the installation process susceptible to man-in-the-middle attacks.
The operational impact of this vulnerability extends beyond simple data interception, as it potentially enables remote code execution through a sophisticated attack vector. An attacker positioned within the network traffic path or capable of performing network-level interference can substitute the legitimate zip file with a maliciously crafted alternative. This substitution attack, known as a man-in-the-middle attack, exploits the lack of secure transport mechanisms in the installation process. The attacker's malicious zip file could contain compromised binaries or scripts that execute during the installation phase, potentially leading to full system compromise. This scenario represents a critical security weakness that aligns with ATT&CK technique T1195.001, which describes the use of unencrypted network protocols for command and control communications.
The risk assessment for CVE-2016-10580 is particularly concerning given that nodewebkit operates in environments where network security controls may be insufficient or bypassed. The vulnerability affects the integrity of the software installation process, potentially compromising the entire system security posture. Attackers could leverage this weakness to deploy malware, establish persistent backdoors, or gain unauthorized access to sensitive systems. The attack surface is broadened because HTTP connections do not provide authentication or encryption, allowing attackers to manipulate the installation flow without detection. This vulnerability demonstrates the critical importance of implementing secure communication protocols in software distribution systems, as outlined in security best practices for software supply chain integrity. Organizations using nodewebkit or similar tools should immediately implement mitigations including network segmentation, traffic monitoring, and protocol upgrades to HTTPS to prevent exploitation of this vulnerability. The potential for remote code execution through this attack vector makes it a high-priority remediation item that requires immediate attention from security teams responsible for maintaining software installation processes.
