Although discovered earlier, the weaponization of CVE-2018-14847 reached maturity in the 6.47.x branch. This vulnerability allowed an unauthenticated attacker to read arbitrary files from the router’s filesystem via the WinBox management port (TCP 8291).
Impact on 6.47.10: By sending a specially crafted packet, an attacker could download the /flash/rw/store/user.dat file, which contained the administrator's password hash (or, in older configurations, the plaintext password).
Why it worked in 6.47.10: MikroTik patched the most egregious file read in 6.45, but researchers discovered bypasses. Version 6.47.10 was vulnerable to a variant that read the nova/etc/snmpd.conf or rw/store/user.dat without authentication.
If the version is so vulnerable, why is it still alive? Three reasons:

The disclosures from 2023-2024 (CVE-2023-32154, CVE-2023-39226) primarily affected RouterOS v7. However, threat actors have not forgotten v6.47.10. It has become a "low-hanging fruit" script-kiddie target.
Botnets like Mēris (which used stolen MikroTik devices for record-breaking DDoS attacks) specifically sought out unpatched v6 devices. 6.47.10 remains a prime candidate because:
