Multiple cross-site request forgery (CSRF) vulnerabilities in D-Link DIR-600 router (rev. Bx) with firmware before 2.17b02 allow remote attackers to hijack the authentication of administrators for requests that (1) create an administrator account or (2) enable remote management via a crafted configuration module to hedwig.cgi, (3) activate new configuration settings via a SETCFG,SAVE,ACTIVATE action to pigwidgeon.cgi, or (4) send a ping via a ping action to diagnostic.php.

D-Link DIR-600 ssdp.cgi command injection

A vulnerability was identified in D-Link DIR-600 up to 2.15WWb02. This vulnerability affects unknown code of the file ssdp.cgi. Such manipulation of the argument HTTP_ST/REMOTE_ADDR/REMOTE_PORT/SERVER_ID leads to command injection. The attack may be launched remotely. The exploit is publicly available and might be used. This vulnerability only affects products that are no longer supported by the maintainer.

D-Link DIR-110/412/600/615/645/815 RCE via service.cgi

Multiple D-Link DIR-series routers, including DIR-110, DIR-412, DIR-600, DIR-610, DIR-615, DIR-645, and DIR-815 firmware version 1.03, contain a vulnerability in the service.cgi endpoint that allows remote attackers to execute arbitrary system commands without authentication. The flaw stems from improper input handling in the EVENT=CHECKFW parameter, which is passed directly to the system shell without sanitization. A crafted HTTP POST request can inject commands that are executed with root privileges, resulting in full device compromise. These router models are no longer supported at the time of assignment and affected version ranges may vary. Exploitation evidence was first observed by the Shadowserver Foundation on 2025-08-21 UTC.

D-Link Devices Unauthenticated RCE

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.

D-Link Devices command.php Unauthenticated RCE

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 DIR-600 HTTP Header hedwig.cgi stack-based overflow

A vulnerability was found in D-Link DIR-600 up to 2.15WWb02. Affected by this vulnerability is an unknown functionality of the file hedwig.cgi of the component HTTP Header Handler. The manipulation of the argument Cookie results in stack-based buffer overflow. It is possible to launch the attack remotely. The exploit has been made public and could be used. This vulnerability only affects products that are no longer supported by the maintainer.

D-Link DIR-600 soap.cgi soapcgi_main os command injection

** UNSUPPORTED WHEN ASSIGNED ** A vulnerability was found in D-Link DIR-600 up to 2.18. It has been rated as critical. This issue affects the function soapcgi_main of the file /soap.cgi. The manipulation of the argument service leads to os command injection. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The identifier VDB-273329 was assigned to this vulnerability. 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.

D-Link DIR-600 Hardware Version B5, Firmware Version 2.18 was discovered to contain a command injection vulnerability via the ST parameter in the lxmldbc_system() function.

D-Link DIR-600 Hardware Version B5, Firmware Version 2.18 was discovered to contain a stack overflow via the gena.cgi binary.

An issue was discovered in soap.cgi?service=WANIPConn1 on D-Link DIR-845 before v1.02b03, DIR-600 before v2.17b01, DIR-645 before v1.04b11, DIR-300 rev. B, and DIR-865 devices. There is Command Injection via shell metacharacters in the NewInternalClient, NewExternalPort, or NewInternalPort element of a SOAP POST request.
