CVE-2024-31621 is a remote code execution (RCE) vulnerability identified in FlowiseAI Inc's Flowise software, specifically versions 1.6.2 and earlier. The vulnerability resides in the api/v1 component, where insufficient validation or sanitization of input scripts allows an attacker to inject and execute arbitrary code remotely. This is categorized under CWE-94, which involves improper control of code injection, a common vector for RCE attacks. The attacker needs network access and low-level privileges but does not require user interaction, making exploitation feasible in many scenarios where the API is exposed. The CVSS 3.1 base score of 7.6 reflects a high severity due to the ease of exploitation (low attack complexity), no user interaction, and the potential for significant integrity impact by executing arbitrary code. Confidentiality impact is limited, and availability impact is low but present. No patches or exploit code are currently publicly available, but the vulnerability poses a serious risk to environments running vulnerable Flowise versions, especially those exposing the API endpoint to untrusted networks. The lack of patch links suggests that a fix may be forthcoming or that users must apply mitigations manually. This vulnerability can lead to full system compromise if exploited, as arbitrary code execution often allows attackers to escalate privileges or move laterally within a network.

The impact of CVE-2024-31621 on organizations worldwide can be severe. Successful exploitation allows remote attackers to execute arbitrary code on systems running vulnerable versions of Flowise, potentially leading to unauthorized control over affected systems. This can compromise the integrity of AI workflows, data processed by Flowise, and the underlying infrastructure. Attackers could manipulate AI models, inject malicious payloads, or disrupt AI services, impacting business operations and trust in AI outputs. Although confidentiality impact is limited, the integrity and availability of AI services can be significantly affected, leading to operational downtime or corrupted AI outputs. Organizations relying on Flowise for AI development or deployment may face increased risk of targeted attacks, especially if the API is exposed to external networks without proper access controls. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, as attackers may develop exploits rapidly once details are public. Industries with high AI adoption, including technology, finance, healthcare, and government sectors, could face heightened risk due to the critical nature of AI services.

To mitigate CVE-2024-31621, organizations should implement the following specific measures: 1) Immediately restrict access to the api/v1 endpoint of Flowise to trusted internal networks only, using network segmentation and firewall rules to prevent exposure to untrusted sources. 2) Implement strict input validation and sanitization on all scripts or commands sent to the API to prevent injection of malicious code. 3) Monitor API logs for unusual or suspicious script submissions that could indicate exploitation attempts. 4) Apply the latest patches or updates from FlowiseAI as soon as they become available; if no official patch exists, consider temporarily disabling or isolating the vulnerable API component. 5) Employ runtime application self-protection (RASP) or web application firewalls (WAF) with custom rules to detect and block malicious payloads targeting the API. 6) Conduct regular security assessments and penetration testing focused on API security to identify and remediate weaknesses. 7) Educate developers and administrators about secure coding practices related to script execution and API security to prevent similar vulnerabilities in future releases.
