Technical ContextAI · show details
This vulnerability is classified as OS Command Injection (CWE-78), which allows attackers to execute arbitrary operating system commands on the host. 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. Affected products include: Dlink Dir-110 Firmware, Dlink Dir-412 Firmware, Dlink Dir-600 Firmware, Dlink Dir-610 Firmware, Dlink Dir-615 Firmware. Version information: version 1.03.

Executive ViewAI
CVE-2018-25115 presents critical security risk, a OS command injection vulnerability rated CVSS 10.0. Successful exploitation could allow attackers to execute arbitrary code or commands on affected systems, potentially leading to full system compromise. Proof-of-concept code is publicly available, increasing the risk of exploitation. Organizations should apply vendor updates immediately when available and implement compensating controls in the interim.
Apply vendor patch. If immediate patching is not feasible: (1) Deploy WAF rules to block injection patterns; (2) Restrict network access to affected components; (3) Enable enhanced logging for suspicious activity.
