Executive Summary

This vulnerability in IBM Langflow OSS versions 1.0.0 through 1.10.3 allows a remote authenticated attacker to execute arbitrary commands. The issue stems from improper validation of the command field in MCP server configurations, which could be exploited to run unauthorized commands on the affected system.

Detection Guidance

Detecting this vulnerability requires checking Langflow OSS versions between 1.0.0 and 1.10.3. Verify installed versions with commands like 'pip show langflow' or 'docker inspect langflow'. Inspect MCP server configurations for improper command field validation in Docker setups.

Impact Analysis

If exploited, this vulnerability could allow attackers to take control of the affected system, steal data, install malware, or disrupt operations. Since it requires authentication, attackers would need valid credentials but could escalate privileges or move laterally within a network.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR and HIPAA requirements for data protection and confidentiality. Organizations may face fines, legal penalties, and reputational damage if exploited due to non-compliance with these regulations.

Mitigation Strategies

Update IBM Langflow OSS to the latest version beyond 1.10.3 to address the improper command validation. Review MCP server configurations to ensure the command field is properly validated and restricted.
