This rule detects HTTP responses (status code 200) that contain the string 'schtasks' followed by '/run' and '/tn' (case-insensitive) in the response body. This pattern indicates the potential for a client system to receive instructions to execute a scheduled task, which could be used for persistence, lateral movement, or other malicious activities.

This rule detects attempts to exploit a command injection vulnerability (CVE-2025-57105) in D-Link devices. Specifically, it looks for HTTP GET requests to '/mng_platform.asp' where the 'addr' parameter contains characters commonly used for command injection, such as semicolons, newlines, backticks, pipes, or dollar signs, which could lead to arbitrary command execution on the device.
