UltraVNC w/ DSM Plugin Detection (2)

UltraVNC seems to be running on the remote port. Upon connection, the remote service on this port sends pseudo-random bytes. It is probably UltraVNC with the new DSM encryption plugin. This plugin tunnels the RFB protocol into a RC4 or AES encrypted stream. %NASLMINLEVEL 70300 C Tenable Network...

RealVNC远程终端控制软件存在远程认证绕过的漏洞

RealVNC VNC Server是一款远程终端控制软件。 RealVNC VNC Server采用的RFB（远程帧缓冲区）协议允许客户端与服务端协商合适的认证方法，协议的实现上存在设计错误，远程攻击者可以绕过认证无需口令实现对服务器的访问。 具体操作细节如下： 1 服务端发送其版本“RFB 003.008\n” 2 客户端回复其版本“RFB 003.008\n” 3 服务端发送1个字节，等于所提供安全类型的编号 3a 服务端发送字节数组说明所提供的安全类型 4 客户端回复1个字节，从3a的数组中选择安全类型 5 如果需要的话执行握手，然后是服务端的“0000” RealVNC...
