CVSS: 7.8EPSS: 1%CPEs: 2EXPL: 2CVE-2018-10070 – MikroTik 6.41.4 - FTP daemon Denial of Service (PoC)
https://notcve.org/view.php?id=CVE-2018-10070
A vulnerability in MikroTik Version 6.41.4 could allow an unauthenticated remote attacker to exhaust all available CPU and all available RAM by sending a crafted FTP request on port 21 that begins with many '\0' characters, preventing the affected router from accepting new FTP connections. The router will reboot after 10 minutes, logging a "router was rebooted without proper shutdown" message. Una vulnerabilidad en MikroTik, versión 6.41.4, podría permitir que un atacante remoto no autenticado agote la CPU y toda la RAM disponible mediante el envío de una petición FTP en el puerto 21 que comienza por muchos caracteres "\0", lo que evita que el router afectado acepte nuevas conexiones FTP. El router se reiniciará tras 10 minutos, mostrando un mensaje de "router was rebooted without proper shutdown". • https://www.exploit-db.com/exploits/44450 http://packetstormsecurity.com/files/147183/MikroTik-6.41.4-Denial-Of-Service.html • CWE-400: Uncontrolled Resource Consumption •
CVSS: 10.0EPSS: 82%CPEs: 14EXPL: 3CVE-2018-7445 – MikroTik RouterOS Stack-Based Buffer Overflow Vulnerability
https://notcve.org/view.php?id=CVE-2018-7445
A buffer overflow was found in the MikroTik RouterOS SMB service when processing NetBIOS session request messages. Remote attackers with access to the service can exploit this vulnerability and gain code execution on the system. The overflow occurs before authentication takes place, so it is possible for an unauthenticated remote attacker to exploit it. All architectures and all devices running RouterOS before versions 6.41.3/6.42rc27 are vulnerable. Se ha encontrado un desbordamiento de búfer en el servicio MikroTik RouterOS SMB al procesar mensajes de petición de sesión NetBIOS. • https://www.exploit-db.com/exploits/44290 http://seclists.org/fulldisclosure/2018/Mar/38 http://www.securityfocus.com/bid/103427 https://www.coresecurity.com/advisories/mikrotik-routeros-smb-buffer-overflow • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

https://notcve.org/view.php?id=CVE-2017-17537
MikroTik RouterBOARD v6.39.2 and v6.40.5 allows an unauthenticated remote attacker to cause a denial of service by connecting to TCP port 53 and sending data that begins with many '\0' characters, possibly related to DNS. MikroTik RouterBOARD v6.39.2 y v6.40.5 permite que un atacante remoto no autenticado provoque una denegación de servicio conectándose al puerto TCP 53 y enviando datos que comiencen por muchos caracteres "\0".

https://notcve.org/view.php?id=CVE-2017-8338
A vulnerability in MikroTik Version 6.38.5 could allow an unauthenticated remote attacker to exhaust all available CPU via a flood of UDP packets on port 500 (used for L2TP over IPsec), preventing the affected router from accepting new connections; all devices will be disconnected from the router and all logs removed automatically. Una vulnerabilidad en MikroTik versión 6.38.5 podría permitir a un atacante remoto no autenticado agotar toda la CPU disponible mediante una inundación de paquetes UDP en el puerto 500 (utilizado para L2TP a través de IPsec), evitando que el enrutador afectado acepte nuevas conexiones; Todos los dispositivos se desconectarán del enrutador y todos los registros se eliminarán automáticamente. • http://seclists.org/fulldisclosure/2017/May/59 https://cxsecurity.com/issue/WLB-2017050062 https://packetstormsecurity.com/files/142538/MikroTik-RouterBoard-6.38.5-Denial-Of-Service.html https://www.vulnerability-lab.com/get_content.php?id=2064 • CWE-400: Uncontrolled Resource Consumption •
