An issue discovered in MikroTik Router v6.46.3 and earlier allows attacker to cause denial of service via misconfiguration in the SSH daemon.

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).

Mikrotik RouterOs before 6.47 (stable tree) suffers from an assertion failure vulnerability in the /ram/pckg/security/nova/bin/ipsec process. An authenticated remote attacker can cause a Denial of Service due to an assertion failure via a crafted packet.

Mikrotik RouterOs before stable 6.47 suffers from a memory corruption vulnerability in the resolver process. By sending a crafted packet, an authenticated remote attacker can cause a Denial of Service.

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

Mikrotik RouterOs before stable version 6.47 suffers from a memory corruption vulnerability in the /nova/bin/lcdstat process. An authenticated remote attacker can cause a Denial of Service (NULL pointer dereference).

Mikrotik RouterOs before stable version 6.47 suffers from a memory corruption vulnerability in the /nova/bin/lcdstat process. An authenticated remote attacker can cause a Denial of Service (NULL pointer dereference). NOTE: this is different from CVE-2020-20253 and CVE-2020-20254. All four vulnerabilities in the /nova/bin/lcdstat process are discussed in the CVE-2020-20250 github.com/cq674350529 reference.

Mikrotik RouterOs before 6.47 (stable tree) suffers from an uncontrolled resource consumption vulnerability in the /nova/bin/route process. An authenticated remote attacker can cause a Denial of Service due to overloading the systems CPU.

Mikrotik RouterOs before 6.47 (stable tree) in the /ram/pckg/advanced-tools/nova/bin/netwatch process. An authenticated remote attacker can cause a Denial of Service due to a divide by zero error.

Mikrotik RouterOs before 6.47 (stable tree) suffers from a memory corruption vulnerability in the /nova/bin/resolver process. An authenticated remote attacker can cause a Denial of Service due to invalid memory access.

Mikrotik RouterOs before 6.47 (stable tree) suffers from a memory corruption vulnerability in the /ram/pckg/wireless/nova/bin/wireless process. An authenticated remote attacker can cause a Denial of Service due via a crafted packet.

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

An integer underflow in the SMB server of MikroTik RouterOS before 6.45.5 allows remote unauthenticated attackers to crash the service.

The SSH daemon on MikroTik routers through v6.44.3 could allow remote attackers to generate CPU activity, trigger refusal of new authorized connections, and cause a reboot via connect and write system calls, because of uncontrolled resource management.

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.

MikroTik RouterOS through 6.44.5 and 6.45.x through 6.45.3 improperly handles the disk name, which allows authenticated users to delete arbitrary files. Attackers can exploit this vulnerability to reset credential storage, which allows them access to the management interface as an administrator without authentication.
