There are some web interfaces without authentication requirements on D-Link DIR-412 A1-1.14WW routers. An attacker can clear the router’s log file via act=clear&logtype=sysact to log_clear.php, which could be used to erase attack traces.

CVE-2019-17353
An issue discovered on D-Link DIR-615 devices with firmware version 20.05 and 20.07. wan.htm can be accessed directly without authentication, which can lead to disclosure of information about the WAN, and can also be leveraged by an attacker to modify the data fields of the page.
CVE-2019-17146
This vulnerability allows remote attackers to execute arbitrary code on affected installations of D-Link DCS-960L v1.07.102. Authentication is not required to exploit this vulnerability. The specific flaw exists within the HNAP service, which listens on TCP port 80 by default. When parsing the SOAPAction request header, the process does not properly validate the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the admin user. Was ZDI-CAN-8458.
CVE-2019-16920
Unauthenticated remote code execution occurs in D-Link products such as DIR-655C, DIR-866L, DIR-652, and DHP-1565. The issue occurs when the attacker sends an arbitrary input to a “PingTest” device common gateway interface that could lead to common injection. An attacker who successfully triggers the command injection could achieve full system compromise. Later, it was independently found that these are also affected: DIR-855L, DAP-1533, DIR-862L, DIR-615, DIR-835, and DIR-825.
CVE-2019-16326
D-Link DIR-601 B1 2.00NA devices have CSRF because no anti-CSRF token is implemented. A remote attacker could exploit this in conjunction with CVE-2019-16327 to enable remote router management and device compromise. NOTE: this is an end-of-life product.
CVE-2019-16327
D-Link DIR-601 B1 2.00NA devices are vulnerable to authentication bypass. They do not check for authentication at the server side and rely on client-side validation, which is bypassable. NOTE: this is an end-of-life product.
