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. |
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. |
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. |
The miniigd SOAP service in Realtek SDK allows remote attackers to execute arbitrary code via a crafted NewInternalClient request, as exploited in the wild through 2023. |
Unauthenticated remote code execution occurs in D-Link products such as DIR-655C, DIR-866L, DIR-652, and DHP-1565. The issue occurs when the attacker sends an arbitrary input to a "PingTest" device common gateway interface that could lead to common injection. An attacker who successfully triggers the command injection could achieve full system compromise. Later, it was independently found that these are also affected: DIR-855L, DAP-1533, DIR-862L, DIR-615, DIR-835, and DIR-825. |
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. |
The D-Link DIR-615 device before v20.12PTb04 doesn't use SSL for any of the authenticated pages. Also, it doesn't allow the user to generate his own SSL Certificate. An attacker can simply monitor network traffic to steal a user's credentials and/or credentials of users being added while sniffing the traffic. |
D-Link DIR-615 Wireless N 300 Router allows authentication bypass via a modified POST request to login.cgi. This issue occurs because it fails to validate the password field. Successful exploitation of this issue allows an attacker to take control of the affected device. |
On the D-Link DIR-615 before v20.12PTb04, once authenticated, this device identifies the user based on the IP address of his machine. By spoofing the IP address belonging to the victim's host, an attacker might be able to take over the administrative session without being prompted for authentication credentials. An attacker can get the victim's and router's IP addresses by simply sniffing the network traffic. Moreover, if the victim has web access enabled on his router and is accessing the web interface from a different network that is behind the NAT/Proxy, an attacker can sniff the network traffic to know the public IP address of the victim's router and take over his session as he won't be prompted for credentials. |
On the D-Link DIR-615 before v20.12PTb04, if a victim logged in to the Router's Web Interface visits a malicious site from another Browser tab, the malicious site then can send requests to the victim's Router without knowing the credentials (CSRF). An attacker can host a page that sends a POST request to Form2File.htm that tries to upload Firmware to victim's Router. This causes the router to reboot/crash resulting in Denial of Service. An attacker may succeed in uploading malicious Firmware. |
D-Link DIR-615 HW: T1 FW:20.09 is vulnerable to Cross-Site Request Forgery (CSRF) vulnerability. This enables an attacker to perform an unwanted action on a wireless router for which the user/admin is currently authenticated, as demonstrated by changing the Security option from WPA2 to None, or changing the hiddenSSID parameter, SSID parameter, or a security-option password. |
D-Link DIR-615 before v20.12PTb04 has a second admin account with a 0x1 BACKDOOR value, which might allow remote attackers to obtain access via a TELNET connection. |
The D-Link DIR-615 with firmware 3.10NA does not require administrative authentication for apply.cgi, which allows remote attackers to (1) change the admin password via the admin_password parameter, (2) disable the security requirement for the Wi-Fi network via unspecified vectors, or (3) modify DNS settings via unspecified vectors. |
The WAN configuration page "wan.htm" on D-Link DIR-615 devices with firmware 20.06 can be accessed directly without authentication which can lead to disclose the information about WAN settings and also leverage attacker to modify the data fields of page. |
An information disclosure issue exist in D-LINK-DIR-615 B2 2.01mt. An attacker can obtain a user name and password by forging a post request to the / getcfg.php page |
A buffer overflow in D-Link DIR-615 C2 3.03WW. The ping_ipaddr parameter in ping_response.cgi POST request allows an attacker to crash the webserver and might even gain remote code execution. |
fmwlan.c on D-Link DIR-615Jx10 devices has a stack-based buffer overflow via the formWlanSetup_Wizard webpage parameter when f_radius_ip1 is malformed. |
fmwlan.c on D-Link DIR-615Jx10 devices has a stack-based buffer overflow via the formWlanSetup webpage parameter when f_radius_ip1 is malformed. |
On D-Link DIR-615 devices, a normal user is able to create a root(admin) user from the D-Link portal. |
On D-Link DIR-615 devices, the User Account Configuration page is vulnerable to blind XSS via the name field. |
