Apache IoTDB | 2.0.1-beta before 2.0.2
How the Exploit Works
The vulnerability stems from the OpenIdAuthorizer component of Apache IoTDB, which incorrectly handles sensitive information. This flaw allows an attacker to exploit the system remotely, gaining unauthorized access to sensitive information. The malicious actor can then insert this sensitive information into the log file, potentially leading to system compromise or unauthorized data leakage.
Conceptual Example Code
The following is a conceptual example of how the vulnerability might be exploited:
GET /IoTDB/OpenIdAuthorizer?info=Sensitive HTTP/1.1
Host: vulnerable_host.com
In this example, an attacker sends a GET request to the OpenIdAuthorizer component of a vulnerable Apache IoTDB instance, attempting to retrieve sensitive information.
