CGI script environment variable

CGI script environment variable

A test CGI script on the server leaks a list of server environment variables in the response page.

Security Misconfiguration (SM)

"CGI Script Environment Variable refers to a vulnerability where a test CGI script on the server unintentionally exposes a list of server environment variables in its response page. These variables may include sensitive information like database paths, SSL configuration, remote IP addresses, and server administrator details. The leakage of such information can provide attackers with valuable insights into the server's configuration, potentially aiding them in planning targeted attacks. Addressing this misconfiguration promptly is crucial to prevent unauthorized access and protect the confidentiality of sensitive information."

How this template works

APIs Selection

The template uses API selection filters to specify the criteria for selecting the API endpoint to test. In this case, it filters based on the response code, ensuring it is between 200 and 299, and also extracts the URL from the response to be used in the subsequent request.

Execute request

The template defines a single request to be executed. It modifies the URL by appending "/cgi-bin/printenv.pl" to the extracted URL variable. This request is sent to the server to test the vulnerability and check if it leaks any sensitive environment variables.

Validation

The template specifies the validation criteria for the response. It checks that the response code is equal to 200 and that the response payload contains any of the specified environment variables, such as 'MYSQL_HOME', 'OPENSSL_CONF', 'REMOTE_ADDR', 'SERVER_ADMIN', or 'Environment Variables'. If the validation criteria are met, it indicates that the vulnerability exists and the server is leaking sensitive information.
