Impact

If misconfigurations are detected in the Alibaba Canal configuration, it could lead to unauthorized access or exposure of sensitive data. Attackers may exploit these vulnerabilities to gain unauthorized access to the system or manipulate the data being synchronized.

How does the module work?

The "Alibaba Canal Config - Detect" module works by sending an HTTP GET request to the "/api/v1/canal/config/1/1" endpoint. It then applies a series of matching conditions to determine if misconfigurations are present.

The matching conditions include:

- Status: The response status code must be 200. - Content-Type: The response header must include the "application/json" value. - Body: The response body must contain the words "ncanal.aliyun.accessKey" and "ncanal.aliyun.secretKey".

If all the matching conditions are met, the module will report the detection of Alibaba Canal configuration information.

Example HTTP request:

GET /api/v1/canal/config/1/1
Content-Type: application/json
