Attack-Flow Graph

Executive Summary

This vulnerability in IBM Langflow OSS versions 1.0.0 through 1.12.2 allows a remote authenticated attacker to execute arbitrary code. It is caused by improper control of code generation, which could let an attacker run malicious commands on the affected system.

Detection Guidance

Detection requires checking for IBM Langflow OSS versions between 1.0.0 and 1.12.2. Inspect installed versions via package managers like pip or system commands. Monitor for unusual code execution patterns or unauthorized modifications in Langflow configurations.

Impact Analysis

If exploited, this vulnerability could allow attackers to take control of the system, steal data, install malware, or disrupt operations. Since it requires authentication, attackers would need valid credentials to exploit it.

Compliance Impact

This vulnerability allows remote authenticated attackers to execute arbitrary code, which could lead to unauthorized data access, modification, or exfiltration. Such risks may violate GDPR's data protection requirements or HIPAA's safeguards for protected health information if exploited.

Mitigation Strategies

Update IBM Langflow OSS to a version beyond 1.12.2 to address the arbitrary code execution flaw. Ensure only authenticated users have access to the system and restrict unnecessary permissions.
