A denial-of-service attack in WPA2, and WPA3-SAE authentication methods in D-Link DIR-X1560, v1.04B04, and DIR-X6060, v1.11B04 allows a remote unauthenticated attacker to disconnect a wireless client via sending specific spoofed SAE authentication frames.

An issue was discovered on D-Link DIR-605L Model B before FW2.11betaB06_hbrf devices, related to the code that handles the authentication values for HNAP. An attacker can cause a denial of service (device crash) or possibly have unspecified other impact by sending a sufficiently long string in the password field of the HTTP Basic Authentication section of the HTTP request.

Buffer overflow in ACME micro_httpd, as used in D-Link DSL2750U and DSL2740U and NetGear WGR614 and MR-ADSL-DG834 routers allows remote attackers to cause a denial of service (crash) via a long string in the URI in a GET request.

** UNSUPPORTED WHEN ASSIGNED ** A vulnerability, which was classified as critical, has been found in D-Link DIR-600M C1 3.08. Affected by this issue is some unknown functionality of the component Telnet Service. The manipulation of the argument username leads to buffer overflow. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. The identifier of this vulnerability is VDB-254576. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. NOTE: Vendor was contacted early and confirmed immediately that the product is end-of-life. It should be retired and replaced.

A Broken Access Control vulnerability in the D-Link DSL-2680 web administration interface (Firmware EU_1.03) allows an attacker to reboot the router by submitting a reboot.html GET request without being authenticated on the admin interface.

The D-Link DIR-816 A2 1.11 router only checks the random token when authorizing a goform request. An attacker can get this token from dir_login.asp and use an API URL /goform/LoadDefaultSettings to reset the router without authentication.

D-Link DCS-825L devices with firmware 1.08 do not employ a suitable mechanism to prevent denial-of-service (DoS) attacks. An attacker can harm the device availability (i.e., live-online video/audio streaming) by using the hping3 tool to perform an IPv4 flood attack. Verified attacks includes SYN flooding, UDP flooding, ICMP flooding, and SYN-ACK flooding.

A vulnerability classified as critical was found in D-Link DI-7003GV2 24.04.18D1 R(68125). This vulnerability affects the function sub_4983B0 of the file /H5/backup.asp?opt=reset of the component Factory Reset Handler. The manipulation leads to denial of service. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used.

On D-Link DIR-605L devices, firmware before 2.08UIBetaB01.bin allows an unauthenticated GET request to trigger a reboot.

D-Link DIR-619 Ax v1.00 was discovered to contain a stack overflow in the function formSetWanPPPoE. This vulnerability allows attackers to cause a Denial of Service (DoS) via the curTime parameter.

On D-Link DIR-823G 2018-09-19 devices, the GoAhead configuration allows /HNAP1 RunReboot commands without authentication to trigger a reboot.

D-Link DIR-619 Ax v1.00 was discovered to contain a stack overflow in the function formSetWanNonLogin. This vulnerability allows attackers to cause a Denial of Service (DoS) via the curTime parameter.

Multiple buffer overflows in the web interface on the D-Link DI-524 router allow remote attackers to cause a denial of service (device crash) or possibly have unspecified other impact via (1) a long username or (2) an HTTP header with a large name and an empty value.

An issue was discovered in /bin/goahead on D-Link DIR-823G devices with the firmware 1.02B03. There is incorrect access control allowing remote attackers to reset the router without authentication via the SetFactoryDefault HNAP API. Consequently, an attacker can achieve a denial-of-service attack without authentication.
