Description
Cudy TR3000 versions before 2.5.42 have a remote code execution vulnerability that allows authenticated administrators to execute commands as root by uploading specially crafted OpenVPN private or tls-auth keys. The vulnerability arises from improper encoding or escaping of output, enabling attackers to inject directives that bypass security restrictions and execute arbitrary code with root privileges.
