Exploit ~upd~ - Mikrotik 6.47.10

The most significant vulnerabilities associated with this era of MikroTik firmware include:

If successfully executed, the flaw allows an attacker to achieve full Remote Code Execution (RCE) via the Wide Area Network (WAN) interface without prior authentication.

Beyond unauthenticated RCE, keeping routers on version 6.47.10 exposes networks to broader infrastructure exploitation chains. If an attacker gains low-level access via brute force or credential leaks, they can leverage underlying architecture flaws to compromise the device completely:

| CVE | Component | Impact | Fixed in version | |-----|-----------|--------|------------------| | CVE-2020-20217 | WinBox | Arbitrary file read (PoC public) | 6.47.8 | | CVE-2020-20214 | HTTP proxy | Memory corruption (DoS) | 6.47.4 | | CVE-2019-3977 | SMB service | Unauthenticated RCE | 6.44.4 | | CVE-2018-1157 | WinBox | Directory traversal (file read) | 6.43 |

The absolute defense against CVE-2021-41987 and associated flaws is upgrading the system.

If you are not explicitly deploying certificates using MikroTik’s built-in SCEP infrastructure, remove the configuration entirely to stop CVE-2021-41987 . /certificate scep server remove [find] Use code with caution.

While often associated with newer 6.x releases (up to 6.49.8), this vulnerability highlights the persistent risk in older versions. It allows an attacker who already has user-level access to escalate their privileges to root (super user).

State-sponsored threat actors and advanced persistent threat (APT) groups have actively scanned for and exploited unpatched RouterOS long-term installations. Security research indicates that groups like BlackTech (also known as HUAPI or Palmerworm) targeted these exact versions to build command-and-control (C2) infrastructure and pivot into internal local area networks (LANs).

While RCE and privilege escalation typically dominate security discussions, denial of service (DoS) vulnerabilities in network infrastructure can be equally devastating, causing network outages that affect entire organizations. /certificate scep server remove [find] Use code with caution

An attacker sends a specially crafted payload to the SCEP server. If they know the scep_server_name value, they can trigger a buffer overflow to achieve RCE via the WAN interface.
