Dlink: >> Dir-600 Security Vulnerabilities
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.

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.

CVE-2014-100005
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.
