This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of D-Link DIR-842 3.13B05 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the processing of HNAP GetCAPTCHAsetting requests. The issue results from the lack of proper handling of sessions. An attacker can leverage this vulnerability to execute arbitrary code in the context of the device. Was ZDI-CAN-10083.

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DAP-1860 1.04B03_HOTFIX WiFi extenders. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the HNAP service, which listens on TCP port 80 by default. When parsing the SOAPAction header, the process does not properly validate a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-10084.

D-Link DSL 2730-U IN_1.10 and IN_1.11 and DIR-600M 3.04 devices have the domain.name string in the DNS resolver search path by default, which allows remote attackers to provide valid DNS responses (and also offer Internet services such as HTTP) for names that otherwise would have had an NXDOMAIN error, by registering a subdomain of the domain.name domain name.

D-Link DIR-865L Ax 1.20B01 Beta devices have Cleartext Transmission of Sensitive Information.

D-Link DIR-865L Ax 1.20B01 Beta devices allow CSRF.

D-Link DIR-865L Ax 1.20B01 Beta devices have Inadequate Encryption Strength.

D-Link DIR-865L Ax 1.20B01 Beta devices have a predictable seed in a Pseudo-Random Number Generator.

D-Link DIR-865L Ax 1.20B01 Beta devices have Cleartext Storage of Sensitive Information.

D-Link DIR-865L Ax 1.20B01 Beta devices allow Command Injection.

D-link DSL-2750U ISL2750UEME3.V1E devices allow approximately 90 seconds of access to the control panel, after a restart, before MAC address filtering rules become active.

D-Link DSP-W215 1.26b03 devices send an obfuscated hash that can be retrieved and understood by a network sniffer.

D-Link DSP-W215 1.26b03 devices allow information disclosure by intercepting messages on the local network, as demonstrated by a Squid Proxy.

D-Link DSL-7740C - Command Injection

D-Link DSL-7740C does not properly validate user input, which allows an authenticated LAN user to inject arbitrary command.

hostapd: UPnP SUBSCRIBE misbehavior in WPS AP

The Open Connectivity Foundation UPnP specification before 2020-04-17 does not forbid the acceptance of a subscription request with a delivery URL on a different network segment than the fully qualified event-subscription URL, aka the CallStranger issue.

An issue was discovered on D-Link DIR-825 Rev.B 2.10 devices. They allow remote attackers to execute arbitrary commands via the date parameter in a system_time.cgi POST request. TRENDnet TEW-632BRP 1.010B32 is also affected.

An issue was discovered on D-Link DIR-825 Rev.B 2.10 devices. They allow remote attackers to execute arbitrary commands via the dns_query_name parameter in a dns_query.cgi POST request. TRENDnet TEW-632BRP 1.010B32 is also affected.

An issue was discovered on D-Link DIR-825 Rev.B 2.10 devices. There is a stack-based buffer overflow in the httpd binary. It allows an authenticated user to execute arbitrary code via a POST to ntp_sync.cgi with a sufficiently long parameter ntp_server.

An issue was discovered on D-Link DIR-825 Rev.B 2.10 devices. They allow remote attackers to execute arbitrary commands via the wps_sta_enrollee_pin parameter in a set_sta_enrollee_pin.cgi POST request. TRENDnet TEW-632BRP 1.010B32 is also affected.

An issue was discovered on D-Link DIR-825 Rev.B 2.10 devices. There is an information disclosure vulnerability via requests for the router_info.xml document. This will reveal the PIN code, MAC address, routing table, firmware version, update time, QOS information, LAN information, and WLAN information of the device.

An issue was discovered on D-Link DIR-878 1.12B01 devices. Because strncpy is misused, there is a stack-based buffer overflow vulnerability that does not require authentication via the HNAP_AUTH HTTP header.
