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 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.

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.

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 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.

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.

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.

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.
