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.

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 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 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.

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.

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.
