MikroTik RouterOS stable before 6.49.7 and long-term through 6.48.6 are vulnerable to a privilege escalation issue. A remote and authenticated attacker can escalate privileges from admin to super-admin on the Winbox or HTTP interface. The attacker can abuse this vulnerability to execute arbitrary code on the system.

Mikrotik RouterOs before stable v7.6 was discovered to contain an out-of-bounds read in the snmp process. This vulnerability allows attackers to execute arbitrary code via a crafted packet.

Mikrotik RouterOs before stable v7.5 was discovered to contain an out-of-bounds read in the hotspot process. This vulnerability allows attackers to execute arbitrary code via a crafted nova message.

Mikrotik RouterOs through stable v6.48.3 was discovered to contain an assertion failure in the component /advanced-tools/nova/bin/netwatch. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted packet.

Mikrotik RouterOs before stable 6.48.2 suffers from a memory corruption vulnerability in the tr069-client process. An authenticated remote attacker can cause a Denial of Service (NULL pointer dereference).

Mikrotik RouterOs before stable 6.48.2 suffers from a memory corruption vulnerability in the ptp process. An authenticated remote attacker can cause a Denial of Service (NULL pointer dereference).

A buffer overflow in Mikrotik RouterOS 6.47 allows unauthenticated attackers to cause a denial of service (DOS) via crafted FTP requests.

A buffer overflow in Mikrotik RouterOS 6.47 allows unauthenticated attackers to cause a denial of service (DOS) via crafted SMB requests.

Mikrotik RouterOs before stable 6.47 suffers from an uncontrolled resource consumption in the memtest process. An authenticated remote attacker can cause a Denial of Service due to overloading the systems CPU.

Mikrotik RouterOs through stable version 6.48.3 suffers from a memory corruption vulnerability in the /nova/bin/detnet process. An authenticated remote attacker can cause a Denial of Service (NULL pointer dereference).

In MikroTik RouterOS through 2021-01-04, the hotspot login page is vulnerable to reflected XSS via the target parameter.

An issue was discovered in Mikrotik RouterOS. Crafting a packet that has a size of 1 byte and sending it to an IPv6 address of a RouterOS box with IP Protocol 97 will cause RouterOS to reboot imminently. All versions of RouterOS that supports EoIPv6 are vulnerable to this attack.
