The login mechanism via device authentication of CGFIDO from Changing Information Technology has an Authentication Bypass vulnerability. If a user visits a forged website, the agent program deployed on their device will send an authentication signature to the website. An unauthenticated remote attacker who obtains…

The passwordless login mechanism in CGFIDO from Changing Information Technology has an Authentication Bypass vulnerability, allowing remote attackers with regular privileges to send a crafted request to switch to the identity of any user, including administrators.

IDExpert from CHANGING Information Technology does not properly validate a specific parameter in the administrator interface, allowing remote attackers with administrative privileges to inject and execute OS commands on the server.

IDExpert from CHANGING Information Technology does not properly validate a parameter for a specific functionality, allowing unauthenticated remote attackers to inject JavsScript code and perform Reflected Cross-site scripting attacks.

The specific API in HWATAIServiSign Windows Version from CHANGING Information Technology does not properly validate the length of server-side inputs. When a user visits a spoofed website, unauthenticated remote attackers can cause a stack-based buffer overflow in the HWATAIServiSign, temporarily disrupting its service.

The specific API in TCBServiSign Windows Version from CHANGING Information Technology does does not properly validate the length of server-side input. When a user visits a spoofed website, unauthenticated remote attackers can cause a stack-based buffer overflow in the TCBServiSign, temporarily disrupting its service.

The specific API in TCBServiSign Windows Version from CHANGING Information Technology does not properly validate server-side input. When a user visits a spoofed website, unauthenticated remote attackers can cause the TCBServiSign to load a DLL from an arbitrary path.

The specific API in TCBServiSign Windows Version from CHANGING Information Technology does not properly validate server-side input. When a user visits a spoofed website, unauthenticated remote attackers can modify the `HKEY_CURRENT_USER` registry to execute arbitrary commands.

The encryption strength of the authorization keys in CHANGING Information Technology TCBServiSign Windows Version is insufficient. When a remote attacker tricks a victim into visiting a malicious website, TCBServiSign will treat that website as a legitimate server and interact with it.

CHANGING Mobile One Time Password's uploading function in a hidden page does not filter file type properly. Remote attackers with administrator privilege can exploit this vulnerability to upload and run malicious file to execute system commands.
