A vulnerability in the Quality of Voice Reporting (QOVR) service of Cisco Prime Collaboration Assurance (PCA) Software could allow an unauthenticated, remote attacker to access the system as a valid user. The vulnerability is due to insufficient authentication controls. An attacker could exploit this vulnerability by connecting to the QOVR service with a valid username. A successful exploit could allow the attacker to perform actions with the privileges of the user that is used for access. This vulnerability affects Cisco PCA Software Releases prior to 12.1 SP2.

Demo Examples

Improper Authentication

CWE-287

The following code intends to ensure that the user is already logged in. If not, the code performs authentication with the user-provided username and password. If successful, it sets the loggedin and user cookies to "remember" that the user has already logged in. Finally, the code performs administrator tasks if the logged-in user has the "Administrator" username, as recorded in the user cookie.


               
}
}
ExitError("Error: you need to log in first");
);
);
DoAdministratorTasks();

Unfortunately, this code can be bypassed. The attacker can set the cookies independently so that the code does not check the username and password. The attacker could do this with an HTTP request containing headers such as:


               
[body of request]

By setting the loggedin cookie to "true", the attacker bypasses the entire authentication check. By using the "Administrator" value in the user cookie, the attacker also gains privileges to administer the software.
