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:
While the vulnerability was patched in 2018, it remains one of the most famous examples of a "feature" in RouterOS becoming a security flaw.
To protect yourself from the Mikrotik 64710 exploit, it's essential to take immediate action:
The MikroTik RouterOS 6.47 series contains several high-profile vulnerabilities, most notably , which affects the SCEP (Simple Certificate Enrollment Protocol) server and allows for Remote Code Execution (RCE) . Version 6.47.10 was the last stable release in the 6.47.x long-term branch before subsequent patches were moved into the 6.48.x and 7.x trees. 🛡️ Critical Exploit: CVE-2021-41987
The exploit targets nearly all MikroTik RouterOS versions released prior to the patch on April 23, 2018. CVE-2018-14847 Detail - NVD mikrotik 64710 exploit
/system package update set channel=long-term check-for-updates download Use code with caution. Step 2: Disable Unused IP Services
When examining the keyword it is important to clarify that "64710" refers specifically to MikroTik RouterOS version 6.47.10 , a long-term release channel build that was introduced to address several security issues while stabilizing network operations . Security researchers and administrators often search for this specific version alongside "exploit" to verify if historical, high-risk vulnerabilities—such as CVE-2021-41987 (a critical SCEP memory corruption flaw) or standard privilege escalation techniques—are active on it or mitigated by it.
The risks associated with the Mikrotik 64710 exploit are significant. If an attacker is able to successfully exploit this vulnerability, they could:
This backdoor allows the attacker to maintain long-term control over your router, turning it into a weapon for cryptojacking, data theft, or inclusion in a global botnet. The single most powerful defense is not complex threat hunting, but fundamental security hygiene: keep your device's firmware updated, restrict access to management interfaces, and use strong, unique credentials. By following the actionable steps outlined in this guide, you can effectively close the door on these insidious and highly persistent threats. Despite MikroTik releasing patches in April 2018 (the
The definitive resolution for CVE-2021-41987 is upgrading the firmware past the vulnerable long-term branches. Administrators should migrate systems to the latest MikroTik Stable or Long-Term Channels to ensure all memory safety overrides are active. 2. Disabling Redundant Network Services
Another critical flaw resolved in the 6.47 release branch involved the system's DNS resolution daemon. An authenticated attacker with sufficient network privileges could force invalid memory access patterns within /nova/bin/resolver . This memory corruption vulnerability allowed attackers to crash the service or potentially execute arbitrary instruction sets under the context of the underlying system user.
This article provides an in-depth technical analysis of the MikroTik exploit, its underlying mechanics, how attackers leverage it, and the concrete steps network administrators must take to secure their infrastructure. What is the MikroTik 64710 Exploit?
The web-based administration interface. API Services (Ports 8728/8729): Automated management ports. 2. The Flaw Version 6
The absolute most effective defense is upgrading to a patched version of RouterOS. MikroTik regularly patches these vulnerabilities in their "Long-term" and "Stable" channels. : Go to System -> Packages -> Check For Updates . Via CLI :
To prevent exploitation:
A: Devices running RouterOS versions 6.29 and earlier are affected by the vulnerability.
In August 2018, researchers from Trustwave’s SpiderLabs discovered that over had been compromised to mine cryptocurrency. The attack, which began in Brazil, redirected users to malicious webpages that loaded the Coinhive JavaScript miner, silently using victims' CPU cycles to mine Monero. The attackers did not install software on the routers; instead, they customized the router's error page to serve the mining script, making detection difficult. By 2021, researchers at Eclypsium estimated that at least 300,000 devices remained vulnerable, effectively acting as "ticking security time bombs".
