Cisco WAG120N is a wireless router.The DDNS settings page in the WEB management interface of Cisco WAG120N has multiple Command Injection Vulnerabilities. By inserting shell commands in submitted parameters (such as Hostname, remote attackers can execute arbitrary commands and obtain root access permissions. To exploit these vulnerabilities, attackers must first pass WEB identity authentication. Test method:1. Access http://www.2cto.com/setup. cgi?
