Protection of sensitive business information from unauthorized access or leakage
import play.api.mvc._
import scala.concurrent.ExecutionContext.Implicits.global
class UserController @Inject()(cc: ControllerComponents) extends AbstractController(cc) {
def getUsernames = Action.async { implicit request: Request[AnyContent] =>
val usernames = UserDAO.getAllUsernames // Assume this method returns all usernames from the database
Future.successful(Ok(Json.toJson(usernames)))
}
def getStrategicInformation = Action.async { implicit request: Request[AnyContent] =>
val strategicInfo = BusinessDAO.getStrategicInformation // Assume this method returns all strategic information from the database
Future.successful(Ok(Json.toJson(strategicInfo)))
}
def getEmployeeInformation = Action.async { implicit request: Request[AnyContent] =>
val employeeInfo = EmployeeDAO.getAllEmployees // Assume this method returns all employee information from the database
Future.successful(Ok(Json.toJson(employeeInfo)))
}
def getClientInformation = Action.async { implicit request: Request[AnyContent] =>
val clientInfo = ClientDAO.getAllClients // Assume this method returns all client information from the database
Future.successful(Ok(Json.toJson(clientInfo)))
}
def getProviderInformation = Action.async { implicit request: Request[AnyContent] =>
val providerInfo = ProviderDAO.getAllProviders // Assume this method returns all provider information from the database
Future.successful(Ok(Json.toJson(providerInfo)))
}
}
The above code is vulnerable to business information leak. It exposes several endpoints that provide sensitive business information such as usernames, strategic information, employee information, client information, and provider information.
The
getUsernames,
getStrategicInformation,
getEmployeeInformation,
getClientInformation,
getProviderInformation methods are all asynchronous actions that retrieve their respective information from the database and return it as a JSON response.
These methods do not implement any form of access control. This means that any user, authenticated or not, can access these endpoints and retrieve the information. This is a serious security vulnerability as it can lead to unauthorized access to sensitive business information.

class UserController @Inject()(cc: ControllerComponents, authAction: AuthAction) extends AbstractController(cc) {
def getUsernames = authAction.async { implicit request: Request[AnyContent] =>
if(request.user.role == "Admin") {
val usernames = UserDAO.getAllUsernames // Assume this method returns all usernames from the database
Future.successful(Ok(Json.toJson(usernames)))
} else {
Future.successful(Forbidden("You do not have access to this resource."))
}
}
def getStrategicInformation = authAction.async { implicit request: Request[AnyContent] =>
if(request.user.role == "Admin") {
val strategicInfo = BusinessDAO.getStrategicInformation // Assume this method returns all strategic information from the database
Future.successful(Ok(Json.toJson(strategicInfo)))
} else {
Future.successful(Forbidden("You do not have access to this resource."))
}
}
def getEmployeeInformation = authAction.async { implicit request: Request[AnyContent] =>
if(request.user.role == "Admin" || request.user.role == "HR") {
val employeeInfo = EmployeeDAO.getAllEmployees // Assume this method returns all employee information from the database
Future.successful(Ok(Json.toJson(employeeInfo)))
} else {
Future.successful(Forbidden("You do not have access to this resource."))
}
}
def getClientInformation = authAction.async { implicit request: Request[AnyContent] =>
if(request.user.role == "Admin" || request.user.role == "Sales") {
val clientInfo = ClientDAO.getAllClients // Assume this method returns all client information from the database
Future.successful(Ok(Json.toJson(clientInfo)))
} else {
Future.successful(Forbidden("You do not have access to this resource."))
}
}
def getProviderInformation = authAction.async { implicit request: Request[AnyContent] =>
if(request.user.role == "Admin" || request.user.role == "Procurement") {
val providerInfo = ProviderDAO.getAllProviders // Assume this method returns all provider information from the database
Future.successful(Ok(Json.toJson(providerInfo)))
} else {
Future.successful(Forbidden("You do not have access to this resource."))
}
}
}
The updated code now includes an
AuthAction which is a custom action builder that checks if a user is authenticated before allowing them to access the endpoint. This is done by injecting
AuthAction into the
UserController and using it to wrap the action bodies.
Inside each action, we now check the role of the authenticated user. If the user has the appropriate role (e.g., "Admin" for getting usernames or strategic information, "HR" for employee information, "Sales" for client information, and "Procurement" for provider information), the request is processed and the information is returned. If the user does not have the appropriate role, a
Forbidden response is returned, indicating that the user does not have access to the requested resource.
This approach implements role-based access control (RBAC), which is a method of regulating access to computer or network resources based on the roles of individual users within your organization. RBAC lets employees have access rights only to the information they need to do their jobs and prevents them from accessing information that doesn't pertain to them.
Please note that the
AuthAction and the user role checking are just placeholders. You would need to implement the actual authentication and authorization mechanisms according to your specific requirements and the capabilities of your chosen authentication and authorization libraries or frameworks.
