: Critical, as it allows unauthenticated attackers to achieve Remote Code Execution (RCE) via the WAN. Affected Versions : Confirmed on RouterOS versions Technical Details & Threat Actor Activity Attack Mechanism
Several well-documented security flaws intersect with MikroTik RouterOS 6.47.10 Long-Term and neighboring software releases: 1. CVE-2021-41987: SCEP Server Heap Buffer Overflow : Remote Code Execution (RCE) mikrotik 64710 exploit
The attacker scans for vulnerable MikroTik routers, particularly targeting the 6.46.8, 6.47.9, or 6.47.10 versions. : Critical, as it allows unauthenticated attackers to
: Versions prior to 6.49.10 (or specific stable releases depending on the patch timeline). : Versions prior to 6
The exploit, often referred to as being used by advanced persistent threats (APTs) such as (also known as Huapi), works by targeting the SCEP service (often on port 80/443, though SCEP can be configured otherwise).
The user.dat file does not store passwords in plaintext but uses a form of obfuscation. The passwords are encrypted via an XOR operation, using a key based on the MD5 hash of the associated username combined with a hardcoded string "283i4jfkai3389" . Because the key is static and can be derived from the username, the attacker's script can automatically decrypt the obfuscated password by performing the reverse XOR operation, presenting the plaintext credentials almost instantly .
