The following is an overview of the issue and how to resolve it. As of the date of publication of this notice, we have not confirmed any attacks that take advantage of this vulnerability. 

【Vulnerability description】

1. Path Traversal 

CCRX has a Path Traversal vulnerability. Path Traversal is an attack on web applications. By manipulating the value of the file path, an attacker can gain access to the file system, including source code and critical system settings.  

Vulnerability number: CVE-2023-34259

2. Denial of Service (DoS) 

There is a vulnerability that makes CCRX unusable by a DoS attack. By manipulating the value of the file path, CCRX may become unresponsive. 

Vulnerability number: CVE-2023-34260

3. User Enumeration

By trying to login many times, an attacker can grasp if there is a login username in data base for device at CCRX login. 

Vulnerability number: CVE-2023-34261


As a countermeasure, we provide firmware that controls the paths managed by CCRX. Please contact your local distributor to apply the firmware. 

For protecting "3. User Enumeration" vulnerability, CCRX already has a feature for avoiding this attack. So, we strongly recommend enabling an account lock function in CCRX. The detailed explanation about account lock function is in User Manual. If the account lock function is configured properly username and password are not compromised, because attacker cannot keep attacking continuously.
