An access control issue in the component formDMZ.cgi of D-Link 816A2FWv1.10CNB05R1B011D88210 allows unauthenticated attackers to set the DMZ service of the device via a crafted POST request.

Command Injection vulnerability in D-Link Dir 816 with firmware version DIR-816A2v1.10CNB04 allows attackers to run arbitrary commands via the urlAdd parameter.

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 dirlogin.asp and use an API URL /goform/setSysAdm to edit the web or system account without authentication.

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 dirlogin.asp and use an API URL /goform/form2userconfig.cgi to edit the system account without authentication.

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 dirlogin.asp and use a hidden API URL /goform/SystemCommand to execute a system command without authentication.

D-Link DIR-816 A2 1.10 B05 allows unauthenticated attackers to arbitrarily reset the device via a crafted tokenid parameter to /goform/form2Reboot.cgi.

An issue was discovered in D-Link DIR-816 A2 1.10 B05 devices. An HTTP request parameter is used in command string construction within the handler function of the /goform/addRouting route. This could lead to Command Injection via Shell Metacharacters.

An issue was discovered in D-Link DIR-816 A2 1.10 B05 devices. Within the handler function of the /goform/addassignment route, a very long text entry for the"'sip" and "smac" fields could lead to a Stack-Based Buffer Overflow and overwrite the return address.

D-link DIR-816 A2 v1.10 is affected by a remote code injection vulnerability. An HTTP request parameter can be used in command string construction in the handler function of the /goform/dirsetWanWifi, which can lead to command injection via shell metacharacters in the statuscheckpppoeuser parameter.

In D-Link DIR-816 A2v1.10CNB04.img the network can be initialized without authentication via /goform/wizardend.

In D-Link DIR-816 A2v1.10CNB04, DIR-878 DIR878FW1.30B08.img a command injection vulnerability occurs in /goform/Diagnosis, after the condition is met, setnum will be spliced into v10 by snprintf, and the system will be executed, resulting in a command injection vulnerability

D-link DIR-816 A2v1.10CNB04.img is vulnerable to Command injection via /goform/NTPSyncWithHost.

D-link DIR-816 A2v1.10CNB04.img is vulnerable to Buffer Overflow via /goform/form2Wan.cgi. When wantype is 3, l2tpusrname will be decrypted by base64, and the result will be stored in v94, which does not check the size of l2tpusrname, resulting in stack overflow.

D-Link DIR-816 A2v1.10CNB04 was discovered to contain a stack overflow via the urladd parameter in /goform/websURLFilterAddDel.

D-Link DIR-816 A2v1.10CNB04 was discovered to contain a stack overflow via the MAC parameter in /goform/editassignment.

D-Link DIR-816 A2v1.10CNB04 was discovered to contain a stack overflow via the proto parameter in /goform/form2IPQoSTcAdd.

D-Link DIR-816 A2v1.10CNB04 was discovered to contain a stack overflow via the addhostfilter parameter in /goform/websHostFilter.

D-Link DIR-816 A2v1.10CNB04 was discovered to contain a stack overflow via the addurlfilter parameter in /goform/websURLFilter.

D-Link DIR-816 A2v1.10CNB04 was discovered to contain a stack overflow via the IPADDR and nvmacaddr parameters in /goform/form2Dhcpip.

D-Link DIR-816 A2v1.10CNB04 was discovered to contain a stack overflow via the lanip parameter in /goform/setNetworkLan.

D-Link DIR-816 A2v1.10CNB04 was discovered to contain a command injection vulnerability via the admuser and admpass parameters in /goform/setSysAdm.
