The vulnerabilities detailed here are not merely theoretical—they have been actively exploited in real-world campaigns. The FOISted vulnerability (CVE-2023-30799) was initially identified in June 2022 and was used to target over 500,000 RouterOS systems in a large-scale attack. Attackers leveraged the privilege escalation flaw to gain super-admin access and deploy backdoors, turning compromised routers into bots for DDoS attacks or proxies for other malicious activities. The APT group behind the attack specifically targeted the SCEP RCE (CVE-2021-41987) on its command-and-control servers, demonstrating how these vulnerabilities fit into sophisticated attacker toolkits.
but was released in March 2022 — any device still running 6.47.10 today is intentionally remaining vulnerable.
An attacker can bypass the restricted RouterOS CLI shell to drop into a standard Linux BusyBox shell, allowing them to install persistent backdoors, network sniffers, or malware. Automated Botnet Exploitation (e.g., Meris, Glupteba)
