Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.3, Flowise record manager and agent memory nodes allowed users to set arbitrary TypeORM DataSource options through the additionalConfig input in packages/components/nodes/recordmanager/MySQLRecordManager/MySQLrecordManager.ts, packages/components/nodes/recordmanager/PostgresRecordManager/PostgresRecordManager.ts, packages/components/nodes/recordmanager/SQLiteRecordManager/SQLiteRecordManager.ts, packages/components/nodes/memory/AgentMemory/MySQLAgentMemory/MySQLAgentMemory.ts, and packages/components/nodes/memory/AgentMemory/AgentMemory.ts. TypeORM DataSource options such as entities, subscribers, and migrations can load local JavaScript files, allowing an authenticated user to execute arbitrary code on the server by uploading a JavaScript payload and referencing it from additionalConfig.entities. This issue is fixed in version 3.1.3.

Detail

Flowise is a powerful application used by developers to manage workflows and data flows efficiently. It is often employed in enterprise environments where handling large datasets and automating processes are critical. The software allows authenticated users to interact with various data storage and processing modules through a web interface. Designed with flexibility in mind, Flowise enables users to set different configurations across data handling components. The application aims to streamline operations and increase productivity by automating repetitive tasks. As a widely used tool, maintaining its security is vital to prevent unauthorized access and misuse.

The detected vulnerability is a Remote Code Execution (RCE) flaw in Flowise, allowing attackers to execute arbitrary code on the server. This vulnerability is particularly severe because it requires user authentication, potentially providing the attacker with elevated access once exploited. Due to its nature, this can lead to complete system compromise if not addressed. Such vulnerabilities are often exploited by injecting malicious code through vulnerable endpoints. The impact can be detrimental, often resulting in unauthorized access to sensitive data. Understanding and addressing this vulnerability is crucial for maintaining the application's security integrity.

Technically, the vulnerability stems from the ability of authenticated users to set arbitrary TypeORM DataSource options in Flowise, including entities that load local JavaScript files. These settings allow the execution of arbitrary code, which attackers can exploit to manipulate server behavior. Specifically, affected endpoints allow the upload and execution of JavaScript files due to improper validation and sanitization of input. Parameters like 'loaderConfig' and 'storeId' are critical in this context, where injected configurations lead to unauthorized code execution. The vulnerability's exploit involves sending crafted requests to the application's API. Such technical flaws highlight the importance of thorough input validation and strict security controls.

When exploited, this vulnerability can have severe consequences, potentially leading to full system compromise. Attackers may gain unauthorized access to sensitive data, alter configurations, or disrupt normal operations by executing malicious software. This could also facilitate further attacks, such as spreading malware or launching denial-of-service attacks against the affected system. The organization's reputation may be harmed, and significant financial costs might be incurred due to data breaches or system downtime. Therefore, understanding and mitigating this vulnerability is crucial to safeguard the application's integrity and protect sensitive information.

Solution Advice
  • Update Flowise to version 3.1.3 or later to patch this vulnerability.
  • Implement strict access controls to ensure only authorized users can access sensitive configurations.
  • Regularly review and audit code and application configurations for potential security loopholes.
  • Deploy additional monitoring tools to detect unusual activities that might indicate an exploit attempt.
  • Educate users and administrators about secure practices, such as proper credential management and vigilance for suspicious activities.
