| Title | Open Web Analytics master Authentication Bypass |
|---|
| Description | Open Web Analytics (OWA) contains an authentication bypass vulnerability in the core controller layer. The checkCapabilityAndAuthenticateUser() method in Core/Controller.php has a logic flaw: when a controller does not explicitly set a required capability via setRequiredCapability() and no authentication cookies are present, the entire authentication check is skipped. This allows unauthenticated remote attackers to execute controller actions that should require authentication, including ProcessEvent and other controllers that do not declare required capabilities.
