RAVA certificate validation system has insufficient validation for user input. An unauthenticated remote attacker can inject arbitrary SQL command to access, modify and delete database.

WriteRegistry function in TSSServiSign component does not filter and verify users’ input, remote attackers can rewrite to the registry without permissions thus perform hijack attacks to execute arbitrary code.

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…

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.

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 digest generation function of NHIServiSignAdapter has not been verified for parameter’s length, which leads to a stack overflow loophole. Remote attackers can use the leak to execute code without privilege.

NHIServiSignAdapter fails to verify the length of digital credential files’ path which leads to a heap overflow loophole. Remote attackers can use the leak to execute code without privilege.

RAVA certification validation system has a path traversal vulnerability. An unauthenticated remote attacker can exploit this vulnerability to bypass authentication and access arbitrary system files.

The digest generation function of NHIServiSignAdapter has not been verified for source file path, which leads to the SMB request being redirected to a malicious host, resulting in the leakage of user's credential.

Multiple functions of NHIServiSignAdapter failed to verify the users’ file path, which leads to the SMB request being redirected to a malicious host, resulting in the leakage of user's credential.

The encryption function of NHIServiSignAdapter fail to verify the file path input by users. Remote attacker can access arbitrary files through the flaw without privilege.

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.

RAVA certificate validation system has insufficient filtering for special parameter of the web page input field. A remote attacker with administrator privilege can exploit this vulnerability to perform arbitrary system command and disrupt service.

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…

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.

RAVA certificate validation system has inadequate filtering for URL parameter. An unauthenticated remote attacker can perform SSRF attack to discover internal network topology base on query response.

IDExpert from CHANGING Information Technology does not properly validate a specific parameter in the administrator interface, allowing remote attackers with administrator privileges to exploit this vulnerability to read arbitrary system files.

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…
