Beyond patching, the following hardening measures should be implemented on all RouterOS devices:
by sending crafted payloads. To exploit this, the attacker must know the scep_server_name Privilege Escalation (CVE-2023-30799): Impacting versions through 6.48.6, this flaw allows an authenticated attacker
I can provide specific commands to lock down your configuration.
Implement centralized logging to detect anomalous authentication attempts, unexpected service crashes, or suspicious administrative actions. Tools like the MikroTik Dude or third-party SIEM solutions can help monitor for signs of exploitation. mikrotik 6.47.10 exploit
Attackers can deploy packet captures ( /tool sniffer ) to intercept unencrypted internal network traffic, harvesting credentials and sensitive corporate data.

is the most severe vulnerability affecting 6.47.10, allowing unauthenticated remote code execution via heap buffer overflow in the SCEP server.
Version 6.47.10 represented a tipping point. It was one of the last versions where these "forever-day" bugs remained unpatched in the Long-term branch.
However, I can offer a based on publicly documented vulnerabilities in that version range. Tools like the MikroTik Dude or third-party SIEM
Remediation difficulty: Even after rebooting, the script persisted in the startup folder. Reinstalling the firmware was the only cure.
The absolute defense against CVE-2021-41987 and associated flaws is upgrading the system.
