CVE-2016-10582 in closurecompiler
Summary
by MITRE
closurecompiler is a Closure Compiler for node.js. closurecompiler downloads binary 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 binary with an attacker controlled binary if the attacker is on the network or positioned in between the user and the remote server.

The vulnerability identified as CVE-2016-10582 affects the closurecompiler package for node.js, which serves as a JavaScript compiler tool that downloads binary resources during its operation. This particular flaw stems from the package's reliance on HTTP protocols for fetching binary components rather than employing secure communication channels. The technical implementation of this vulnerability creates a significant security risk within the software supply chain, as it exposes users to man-in-the-middle attack vectors that can compromise the integrity of downloaded binaries. The root cause of this vulnerability aligns with CWE-319, which specifically addresses the exposure of sensitive information through improper use of network protocols, and represents a classic example of insecure communication practices in software distribution mechanisms.
The operational impact of this vulnerability extends beyond simple data interception, as it creates a pathway for remote code execution attacks when an attacker successfully substitutes legitimate binaries with malicious alternatives. When the closurecompiler package downloads its required binary resources over unencrypted HTTP connections, any network traffic between the user and the remote server becomes susceptible to manipulation by adversaries who occupy the network path. This scenario particularly threatens environments where attackers can position themselves between the client and server, such as public Wi-Fi networks, compromised routers, or network infrastructure that lacks proper security controls. The vulnerability's potential for remote code execution places it within the ATT&CK framework under the T1190 technique for Exploit Public-Facing Application, where attackers leverage insecure network communications to inject malicious code into legitimate software packages.
Mitigation strategies for this vulnerability require immediate implementation of secure communication protocols throughout the software distribution pipeline. The most effective approach involves upgrading the closurecompiler package to utilize HTTPS connections for all binary downloads, thereby implementing cryptographic protection that prevents man-in-the-middle attacks. Organizations should also consider implementing certificate pinning mechanisms to further strengthen the integrity verification process and prevent attackers from substituting certificates during the download process. Additionally, security teams should establish monitoring procedures to detect unusual network traffic patterns that might indicate binary substitution attempts. The remediation process should include updating all affected systems and verifying that the updated packages properly implement secure communication channels, as outlined in industry best practices for secure software development and distribution. Organizations must also consider implementing network segmentation and traffic inspection tools to detect and prevent unauthorized modifications to software packages during transit, particularly in environments where network security controls are insufficient to prevent such attacks.
