What is CVE-2018-25115?

Certain D-Link DIR-series routers are vulnerable due to improper input handling at the service.cgi endpoint, allowing remote attackers to execute arbitrary system commands without authentication. This vulnerability arises when attacker-supplied input via the EVENT=CHECKFW parameter is processed unsafely, enabling the execution of commands with root privileges. Given that the mentioned router models are no longer supported, it is critical for users to implement necessary security precautions to safeguard their networks against potential exploitation.
