Attack-Flow Graph

Executive Summary

This vulnerability in IBM Langflow OSS versions 1.0.0 through 1.12.2 allows a remote attacker to execute arbitrary code. It is caused by improper control of code generation, meaning the system does not properly restrict or validate code that is generated or executed.

Detection Guidance

To detect this vulnerability, check the installed version of IBM Langflow OSS. If it is between 1.0.0 and 1.12.2, the system is potentially vulnerable. Use commands like 'pip show langflow' or 'langflow --version' to verify the version.

Impact Analysis

An attacker could exploit this to run malicious code on your system, potentially leading to unauthorized access, data theft, or system compromise. Since the vulnerability has a CVSS score of 9.8, it is highly severe and could allow full control over affected systems.

Compliance Impact

This vulnerability could lead to unauthorized access or data breaches, which may violate compliance requirements under GDPR, HIPAA, or other regulations. Organizations using affected versions of IBM Langflow OSS may face legal and regulatory penalties due to insufficient security controls.

Mitigation Strategies

Upgrade IBM Langflow OSS to a version beyond 1.12.2 to address the arbitrary code execution flaw. If immediate upgrade is not possible, restrict network access to Langflow instances and monitor for suspicious activity.
