A Remote Code Execution(RCE) vulnerability exists in some designated applications in ServiSign security plugin, as long as the interface is captured, attackers are able to launch RCE and executes arbitrary command on target system via malicious crafted scripts.

An arbitrary-file-access vulnerability exists in ServiSign security plugin, as long as the attackers learn the specific API function, they may access arbitrary files on target system via crafted API parameter.

An arbitrary-file-access vulnerability exists in ServiSign security plugin, as long as the attackers learn the specific API function, they may access arbitrary files on target system via crafted API parameter.

Changing MOTP (Mobile One Time Password) system’s specific function parameter has insufficient validation for user input. A attacker in local area network can perform SQL injection attack to read, modify or delete backend database without authentication.

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.

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.

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.

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.

ChangingTech MegaServiSignAdapter component has a path traversal vulnerability within its file reading function. An unauthenticated remote attacker can exploit this vulnerability to access arbitrary system files.

ChangingTech MegaServiSignAdapter component has a vulnerability of improper input validation. An unauthenticated remote attacker can exploit this vulnerability to access and modify HKEY_CURRENT_USER subkey (ex: AutoRUN) in Registry where malicious scripts can be executed to take control of the system or to terminate the service.

ChangingTech MegaServiSignAdapter component has a vulnerability of Out-of-bounds Read due to insufficient validation for parameter length. An unauthenticated remote attacker can exploit this vulnerability to access partial sensitive content in memory and disrupts partial services.

ChangingTec ServiSign component has insufficient filtering for special characters in the connection response parameter. An unauthenticated remote attacker can host a malicious website for the component user to access, which triggers command injection and allows the attacker to execute arbitrary system command to perform arbitrary system operation or disrupt service.

ChangingTec ServiSign component has a path traversal vulnerability. An unauthenticated LAN attacker can exploit this vulnerability to bypass authentication and access arbitrary system files.

ChangingTec ServiSign component has a path traversal vulnerability due to insufficient filtering for special characters in the DLL file path. An unauthenticated remote attacker can host a malicious website for the component user to access, which triggers the component to load malicious DLL files under arbitrary file path and allows the attacker to perform arbitrary system operation and disrupt of service.

ChangingTec MOTP system has a path traversal vulnerability. A remote attacker with administrator’s privilege can exploit this vulnerability to access arbitrary system files.
