Impact

If credentials are exposed in the help the help desk JavaScript file, it can lead to unauthorized access to sensitive information or systems. Attackers could potentially exploit these exposed credentials to gain unauthorized privileges, compromise data, or perform malicious activities within the ServiceNow environment. It is crucial to address this vulnerability promptly to prevent any potential security breaches.

How the module works?

The module works by analyzing the help the help desk JavaScript file in ServiceNow and applying specific matching conditions to identify exposed credentials. It sends an HTTP GET request to the "{%RootURL%}/HelpTheHelpDesk.jsdbx" path and checks for two matching conditions:

- Matching Condition 1: It searches for the presence of the string "var httpPassword = "encrypt:" in the response body. This indicates the potential presence of an encrypted password in the JavaScript file. - Matching Condition 2: It verifies that the HTTP response status code is 200, indicating a successful request.

If both matching conditions are met, the module reports a vulnerability related to credential exposure in the ServiceNow help the help desk JavaScript file.

Example HTTP Request:

GET {%RootURL%}/HelpTheHelpDesk.jsdbx

Matching Conditions:

- Condition 1: The response body contains the string "var httpPassword = "encrypt:" - Condition 2: The HTTP response status code is 200

It is important to address any identified vulnerabilities and ensure that credentials are properly protected to maintain the security of the ServiceNow helpdesk environment.
