: The internal SCEP server feature must be explicitly enabled and exposed to network traffic.
Despite MikroTik releasing patches in April 2018 (the company fixed the zero-day within a day of being notified), a staggering number of devices remain exposed. There are several reasons for this:
Version 6.47.10 is explicitly tracked as one of the final builds containing this code footprint prior to the release of definitive mitigations. The attack vector is technically limited because an administrator must have explicitly enabled the SCEP server and exposed it to the public WAN.
Some older, misconfigured RouterOS versions exposed a management service on TCP port 64710. This was often a side effect of the MikroTik Bandwidth Test Server or misrouted API services. Scanning tools like Shodan occasionally show port 64710 open, leading some to call it "the 64710 exploit." However, that is a configuration issue, not an exploit. mikrotik 64710 exploit

Allows an unauthenticated remote attacker to achieve Remote Code Execution (RCE) via the WAN interface. Vulnerability Type: Heap-based buffer overflow.
The web-based administration interface. API Services (Ports 8728/8729): Automated management ports. 2. The Flaw
. Tracked globally under the identifier CVE-2021-41987 , this specific vulnerability allows a remote, unauthenticated attacker to execute arbitrary code with elevated privileges, potentially resulting in a complete takeover of the underlying network infrastructure. Because MikroTik hardware is widely deployed across enterprise networks, internet service providers (ISPs), and remote office environments, unpatched devices face severe exposure to targeted network penetration and botnet recruitment. Anatomy of the CVE-2021-41987 Vulnerability The attack vector is technically limited because an
The primary target of the initial exploit is the user.dat file. This file stores the usernames and passwords for all user accounts on the RouterOS device .
Beyond credential theft, researchers discovered that attackers could use "command 1" within the protocol to write files, allowing for the creation of a root busybox shell for persistent access.

MikroTik released version 6.47.10 as part of its stable "long-term" lifecycle to patch serious vulnerabilities discovered during the 2021-2022 threat landscape. However, because many organizations neglect timely firmware management, devices running 6.47.10 occasionally remain exposed to older unpatched vectors or configuration errors. 1.
