eSMTP - Config Discovery

What is "eSMTP - Config Discovery"?

The "eSMTP - Config Discovery" module is designed to detect misconfigurations in the eSMTP configuration. eSMTP is a software that allows for the sending and receiving of email messages. This module focuses on identifying potential vulnerabilities in the eSMTP configuration.

This module has a severity level of high, indicating that the detected misconfigurations can have a significant impact on the security of the eSMTP setup.

Impact

If misconfigurations are found, attackers may be able to exploit them to gain unauthorized access to the eSMTP server or intercept sensitive email communications. This can lead to unauthorized access to sensitive information, email account compromise, and potential data breaches.

How the module works?

The "eSMTP - Config Discovery" module works by sending HTTP requests to the target server and analyzing the responses. It specifically looks for the presence of the .esmtprc file, which contains the eSMTP configuration.

The module uses the following matching conditions to identify potential misconfigurations:

- Header: The response header must contain the word "text/plain". - Body: The response body must contain the words "hostname", "username", and "password". - Status: The response status code must be 200.

If all the matching conditions are met, the module reports a potential vulnerability, indicating that the eSMTP configuration may be exposed and accessible to unauthorized individuals.
