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 •

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 •

A vulnerability in the network stack of MikroTik Version 6.38.5 released 2017-03-09 could allow an unauthenticated remote attacker to exhaust all available CPU via a flood of TCP RST packets, preventing the affected router from accepting new TCP connections. Vulnerabilidad en la pila de la red de MikroTik Version 6.38.5 liberada 09-03-2017 podría permitir a un atacante remoto no autenticado agotar toda la CPU disponible a través de una inundación de paquetes TCP RST, evitando que el enrutador afectado acepte nuevas conexiones TCP.

https://notcve.org/view.php?id=CVE-2017-6444
The MikroTik Router hAP Lite 6.25 has no protection mechanism for unsolicited TCP ACK packets in the case of a fast network connection, which allows remote attackers to cause a denial of service (CPU consumption) by sending many ACK packets. After the attacker stops the exploit, the CPU usage is 100% and the router requires a reboot for normal operation. El router MikroTik hAP Lite 6.25 no tiene mecanismo de protección para paquetes TCP ACK no solicitados en el caso de una conexión de red rápida. lo que permite a atacantes remotos provocar una denegación de servicio (consumo de CPU) enviando muchos paquetes ACK. Después de que el atacante detenga el exploit, el uso de CPU es 100% y el router requiere un reinicio para un funcionamiento normal • https://www.exploit-db.com/exploits/41601 http://www.exploitalert.com/view-details.html?id=26137 https://cxsecurity.com/issue/WLB-2017030029 https://packetstormsecurity.com/files/141449/Mikrotik-Hap-Lite-6.25-Denial-Of-Service.html • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2017-6297
The L2TP Client in MikroTik RouterOS versions 6.83.3 and 6.37.4 does not enable IPsec encryption after a reboot, which allows man-in-the-middle attackers to view transmitted data unencrypted and gain access to networks on the L2TP server by monitoring the packets for the transmitted data and obtaining the L2TP secret. El Cliente L2TP en MikroTik RouterOS versiones 6.83.3 y 6.37.4 no habilita el cifrado IPsec después de un reinicio, lo que permite a atacantes man-in-the-middle ver los datos transmitidos sin cifrar y obtener acceso a las redes en el servidor L2TP monitorizando los paquetes para los datos transmitidos y obtener el secreto L2TP. • http://www.securityfocus.com/bid/96447 https://blog.milne.it/2017/02/24/mikrotik-routeros-security-vulnerability-l2tp-tunnel-unencrypted-cve-2017-6297 • CWE-311: Missing Encryption of Sensitive Data •
