"The version of DLink installed on the remote host is prior to 1.07b03. It is, therefore, affected by

  - The UPnP endpoint URL /gena.cgi in the D-Link DIR-859 Wi-Fi router 1.05 and 1.06B01 Beta01 
    allows an Unauthenticated remote attacker to execute system commands as root, by sending a 
    specially crafted HTTP SUBSCRIBE request to the UPnP service when connecting to the local 
    network. (CVE-2019-17621)
  
  - D-Link DIR-859 1.05 and 1.06B01 Beta01 devices allow remote attackers to execute arbitrary OS 
    commands via a urn: to the M-SEARCH method in ssdpcgi() in /htdocs/cgibin, because HTTP_ST is 
    mishandled. The value of the urn: service/device is checked with the strstr function, which 
    allows an attacker to concatenate arbitrary commands separated by shell metacharacters. 
    (CVE-2019-20215)
