CVE-2016-10524 in i18n-node-angular
Summary
by MITRE
i18n-node-angular is a module used to interact between i18n and angular without using additional resources. A REST API endpoint that is used for development in i18n-node-angular before 1.4.0 was not disabled in production environments a malicious user could fill up the server causing a Denial of Service or content injection.

The vulnerability identified as CVE-2016-10524 affects the i18n-node-angular module, a popular JavaScript library designed to facilitate internationalization between node.js backend applications and angular frontend frameworks. This module provides a seamless integration layer for managing translations and localization within web applications. The flaw stems from improper configuration of development-only REST API endpoints that were intended solely for testing and debugging purposes during the development phase. These endpoints, which should have been disabled or secured in production environments, remained accessible to unauthorized users, creating a significant security risk that could be exploited by malicious actors.
The technical implementation of this vulnerability involves the exposure of internal development APIs that handle translation data and configuration management. When these endpoints remain active in production, they create multiple attack vectors for potential exploitation. The primary risk manifests through two distinct attack patterns: denial of service through resource exhaustion and content injection attacks. Attackers can exploit the exposed endpoints to flood the server with requests, consuming available resources such as memory and processing power, ultimately leading to service unavailability for legitimate users. Additionally, the endpoints may allow for content injection attacks where malicious data can be inserted into the translation system, potentially compromising the integrity of the application's internationalization features.
The operational impact of this vulnerability extends beyond simple service disruption to encompass broader security implications within the application ecosystem. Organizations using affected versions of i18n-node-angular face risks of data corruption, unauthorized modification of translation files, and potential escalation to more serious attacks depending on the application architecture. The vulnerability directly maps to CWE-94, which describes "Improper Control of Generation of Code" and CWE-400, which addresses "Uncontrolled Resource Consumption." From an attack perspective, this vulnerability aligns with ATT&CK techniques including T1499.004 for "Network Denial of Service" and potentially T1566.001 for "Phishing" if the content injection leads to malicious payload delivery through compromised translation files.
Mitigation strategies for this vulnerability require immediate action to disable or secure the exposed development endpoints in production environments. Organizations should implement proper environment-specific configuration management to ensure that development-only features are completely disabled in production deployments. The recommended approach includes updating to version 1.4.0 or later where the vulnerability has been addressed through proper endpoint disabling mechanisms. Additional protective measures involve implementing network-level access controls, firewall rules to restrict access to development endpoints, and regular security audits to ensure no unintended endpoints remain exposed. Organizations should also establish robust configuration management practices that automatically validate endpoint accessibility based on environment settings and implement continuous monitoring to detect unauthorized access attempts to sensitive internal APIs.
