api-gateway-deploy OS Command Injection and Container Escape Vulnerability Analysis

Critical Vulnerability Information Vulnerability Summary Vulnerability Description: contains a severe attack chain involving OS command injection and privilege escalation. This allows attackers to execute arbitrary commands with root privileges inside the container, potentially leading to container escape and unauthorized infrastructure modifications. Affected and Fixed Versions Affected Versions: - Dockerfile: v1.0.0 - entrypoint.sh: v1.0.0 Fixed Versions: - Dockerfile: v1.0.1 - entrypoint.sh: v1.0.1 Vulnerability Details 1. OS Command Injection & Parameter Injection (CWE-78, CWE-88): - The vulnerability lies in the script, which uses the command to perform string replacement in a temporary Swagger file. The variable is used directly without proper sanitization or delimiter handling. - Vulnerable code snippet: - Attackers can craft malicious strings (e.g., ) to break the context of the command, resulting in OS command injection and parameter injection. 2. Execution with Unnecessary Privileges & Flawed Permission Management (CWE-250, CWE-269): - The Dockerfile lacks a directive, causing processes to run as root by default. - The environment fails to restrict the scope of the injected script, providing full administrative access to the container and pre-configured AWS CLI credentials. Vulnerability Dependency and Chain Explanation Attack Chain: RCE (CWE-78/88) acts as the "key," while Root Execution (CWE-250/269) acts as the "door," enabling complete system control. Unified Impact: Fixing only permission management without addressing injection, or addressing injection without hardening the container, can still lead to unauthorized code execution and other logical vulnerabilities. Remediation: All four CWEs were addressed synchronously in version 1.0.1; splitting these fixes would misrepresent the technical reality. Remediation Measures Fixed in version 1.0.1 with the following measures: Implemented strict input sanitization and safe delimiters in . Enforced non-root user execution ( ) in the Dockerfile. Established mandatory security quality gates (Semgrep, Checkov, Trivy, Gitleaks).
