Publicly exposed Kafdrop Interface

What is the "Publicly exposed Kafdrop Interface?"

The "Publicly exposed Kafdrop Interface" module is designed to detect misconfigurations in the Kafdrop interface, a web-based tool for monitoring Apache Kafka clusters. This module has a low severity level and was authored by dhiyaneshDk.

Impact

If the Kafdrop interface is publicly exposed, it can potentially lead to unauthorized access and information leakage. Attackers may be able to gain insights into the Kafka cluster and its configuration, which could be used to exploit vulnerabilities or launch further attacks.

How the module works?

The module works by sending HTTP requests to the target and matching the responses against specific conditions. It looks for the presence of certain keywords, such as "<title>Kafdrop: Broker List</title>" and "Kafka Cluster Overview", to identify if the Kafdrop interface is exposed.

By detecting these keywords, the module can determine if the Kafdrop interface is accessible to the public. If a match is found, the module will report a misconfiguration vulnerability.

Here is an example of an HTTP request that the module may send:

GET /kafdrop HTTP/1.1
Host: example.com

The module also includes additional metadata, such as the maximum number of requests allowed (max-request: 1), which provides further context for the scan.
