Vulnerability details
The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The vulnerability exists due to insufficient validation of user-supplied input. A remote unauthenticated attacker can execute arbitrary OS commands via shell metacharacters in a crafted /HNAP1 request when the GetNetworkTomographyResult function calls the system function with an untrusted input parameter named Address.
