D-LINK DIR-806 1200M11AC wireless router DIR806A1_FW100CNb11 is vulnerable to command injection due to lax filtering of HTTP_ST parameters.

An issue was discovered in D-Link DIR-806 devices. There is a 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.

A Command Injection vulnerability exists in the /var/www/cgi-bin/rtpd.cgi script in D-Link IP Cameras DCS-3411/3430 firmware 1.02, DCS-5605/5635 1.01, DCS-1100L/1130L 1.04, DCS-1100/1130 1.03, DCS-1100/1130 1.04_US, DCS-2102/2121 1.05_RU, DCS-3410 1.02, DCS-5230 1.02, DCS-5230L 1.02, DCS-6410 1.00, DCS-7410 1.00, DCS-7510 1.00, and WCS-1100 1.02, which could let a remote malicious user execute arbitrary commands through the camera’s web interface.

An authenticated OS command injection vulnerability exists in various D-Link routers (tested on DIR-615H1 running firmware version 8.04) via the tools_vct.htm endpoint. The web interface fails to sanitize input passed from the ping_ipaddr parameter to the tools_vct.htm diagnostic interface, allowing attackers to inject arbitrary shell commands using backtick encapsulation. With default credentials, an attacker can exploit this blind injection vector to execute arbitrary commands.

D-LINK DWL-6610 FW_v_4.3.0.8B003C was discovered to contain a command injection vulnerability in the function config_upload_handler. This vulnerability allows attackers to execute arbitrary commands via the configRestore parameter.

A vulnerability was found in D-Link DIR‑818L up to 1.05B01. This issue affects the function getenv of the file /htdocs/cgibin of the component ssdpcgi. The manipulation leads to command injection. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used.

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DIR-1935 1.03 routers. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the handling of SetStaticRouteIPv4Settings requests to the web management portal. When parsing subelements within the StaticRouteIPv4Data element, 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 root. Was ZDI-CAN-16147.

The web interface of multiple D-Link routers, including DIR-600 rev B (≤2.14b01) and DIR-300 rev B (≤2.13), contains an unauthenticated OS command injection vulnerability in command.php, which improperly handles the cmd POST parameter. A remote attacker can exploit this flaw without authentication to spawn a Telnet service on a specified port, enabling persistent interactive shell access as root.

An OS command injection vulnerability exists in various legacy D-Link routers—including DIR-300 rev B and DIR-600 (firmware ≤ 2.13 and ≤ 2.14b01, respectively)—due to improper input handling in the unauthenticated command.php endpoint. By sending specially crafted POST requests, a remote attacker can execute arbitrary shell commands with root privileges, allowing full takeover of the device. This includes launching services such as Telnet, exfiltrating credentials, modifying system configuration, and disrupting availability. The flaw stems from the lack of authentication and inadequate sanitation of the cmd parameter.

D-LINK DWL-6610 FW_v_4.3.0.8B003C was discovered to contain a command injection vulnerability in the function sub_2EF50. This vulnerability allows attackers to execute arbitrary commands via the manual-time-string parameter.

An OS command injection vulnerability exists in multiple D-Link routers—confirmed on DIR-300 rev A (v1.05) and DIR-615 rev D (v4.13)—via the authenticated tools_vct.xgi CGI endpoint. The web interface fails to properly sanitize user-supplied input in the pingIp parameter, allowing attackers with valid credentials to inject arbitrary shell commands. Exploitation enables full device compromise, including spawning a telnet daemon and establishing a root shell. The vulnerability is present in firmware versions that expose tools_vct.xgi and use the Mathopd/1.5p6 web server. No vendor patch is available, and affected models are end-of-life.

D-LINK DIR-806 1200M11AC wireless router DIR806A1_FW100CNb11 is vulnerable to command injection.

An issue was discovered on D-Link DIR-816 A2 1.10 B05 devices. An HTTP request parameter is used in command string construction in the handler function of the /goform/form2systime.cgi route. This could lead to command injection via shell metacharacters in the datetime parameter.

D-Link DCH-M225 1.05b01 and earlier devices allow remote attackers to execute arbitrary OS commands via shell metacharacters in the spotifyConnect.php userName parameter.
