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.
A vulnerability was found in D-Link DIR-815 1.01. It has been declared as critical. This vulnerability affects the function sub_403794 of the file hedwig.cgi. The manipulation leads to stack-based buffer overflow. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used.
A vulnerability classified as critical was found in D-Link DAP-1360, DIR-300, DIR-615, DIR-615GF, DIR-615S, DIR-615T, DIR-620, DIR-620S, DIR-806A, DIR-815, DIR-815AC, DIR-815S, DIR-816, DIR-820, DIR-822, DIR-825, DIR-825AC, DIR-825ACF, DIR-825ACG1, DIR-841, DIR-842, DIR-842S, DIR-843, DIR-853, DIR-878, DIR-882, DIR-1210, DIR-1260, DIR-2150, DIR-X1530, DIR-X1860, DSL-224, DSL-245GR, DSL-2640U, DSL-2750U, DSL-G2452GR, DVG-5402G, DVG-5402G, DVG-5402GFRU, DVG-N5402G, DVG-N5402G-IL, DWM-312W, DWM-321, DWR-921, DWR-953 and Good Line Router v2 up to 20240112. This vulnerability affects unknown code of the file /devinfo of the component HTTP GET Request Handler. The manipulation of the argument area with the input notice|net|version leads to information disclosure. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. VDB-251542 is the identifier assigned to this vulnerability.
An issue discovered in D-Link dir815 v.1.01SSb08.bin allows a remote attacker to execute arbitrary code via a crafted POST request to the service parameter in the soapcgi_main function of the cgibin binary component.
webinc/js/info.php on D-Link DIR-816L 2.06.B09_BETA and DIR-803 1.04.B02 devices allows XSS via the HTTP Referer header. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. NOTE: this is typically not exploitable because of URL encoding (except in Internet Explorer) and because a web page cannot specify that a client should make an additional HTTP request with an arbitrary Referer header
D-Link DIR-815 REV. B (with firmware through DIR-815_REVB_FIRMWARE_PATCH_2.07.B01) devices have permission bypass and information disclosure in /htdocs/web/getcfg.php, as demonstrated by a /getcfg.php?a=%0a_POST_SERVICES%3DDEVICE.ACCOUNT%0aAUTHORIZED_GROUP%3D1 request.
D-Link DIR-815 REV. B (with firmware through DIR-815_REVB_FIRMWARE_PATCH_2.07.B01) devices have XSS in the RESULT parameter to /htdocs/webinc/js/info.php.
