  script_tag(name:"insight", value:"The following flaws exist:

  - CVE-2019-10891: Command injection in function hnap_main, which calls system() without checking
  the parameter that can be controlled by user, and finally allows remote attackers to execute
  arbitrary shell commands with a special HTTP header

  - CVE-2019-10892: Stack-based buffer overflow in function hnap_main at /htdocs/cgibin.
  The function will call sprintf without checking the length of strings in parameters given by HTTP
  header and can be controlled by users.

  - CVE-2023-43128: Command injection due to lax filtering of HTTP_ST parameters

  - CVE-2023-43129: Command injection due to lax filtering of REMOTE_PORT parameters

  - CVE-2023-43130: Command injection

  - CVE-2024-0717: The manipulation of the argument area in /devinfo leads to information
  disclosure

  - CVE-2025-4340: Command injection");

  options are to upgrade to a newer release, disable respective features, remove the product or
  replace the product by another one.

  Note: The vendor states that technical support for DIR-806 has ended in 01.02.2020, therefore
  most probably no effort will be made to provide a fix for these vulnerabilities.");
