Attack-Flow Graph

Executive Summary

This vulnerability involves improper neutralization of argument delimiters in the install_packages() method of the AWS Bedrock AgentCore Python SDK before version 1.18.1. A remote authenticated user could exploit this to execute arbitrary commands within the Code Interpreter sandbox by providing specially crafted package name arguments.

Detection Guidance

Detecting this vulnerability requires checking the version of the AWS Bedrock AgentCore Python SDK installed on your system. Run the command 'pip show amazon-bedrock-agentcore-python-sdk' to check the installed version. If the version is below 1.18.1, the system is vulnerable.

Impact Analysis

If exploited, this vulnerability could allow an attacker to run unauthorized commands on the affected system, potentially leading to data breaches, system compromise, or unauthorized access to sensitive information within the sandbox environment.

Compliance Impact

This vulnerability could potentially allow unauthorized command execution within a sandboxed environment, which may lead to data exfiltration or manipulation. For GDPR, this could result in unauthorized access to personal data, violating principles of data protection and user rights. For HIPAA, it might enable unauthorized access to protected health information, compromising confidentiality and integrity requirements.

Mitigation Strategies

Upgrade the AWS Bedrock AgentCore Python SDK to version 1.18.1 or later to address the vulnerability.
