Mikrotik Routeros 6.42.12 ~~long term~~~

An issue was discovered in the Winbox service of MikroTik RouterOS long-term release v6.43.13 through v6.49.13 and stable v6.43 through v7.17.2. A patch is available in the stable release v6.49.18. A discrepancy in response size between connection attempts made with a valid username and those with an invalid username allows attackers to enumerate for valid accounts.

Mikrotik RouterOS RADVD Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Mikrotik RouterOS. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the Router Advertisement Daemon. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of root. . Was ZDI-CAN-19797.

MikroTik RouterOS v7.1 to 7.11 was discovered to contain incorrect access control mechanisms in place for the Rest API.

The web server used by MikroTik RouterOS version 6 is affected by a heap memory corruption issue. A remote and unauthenticated attacker can corrupt the server's heap memory by sending a crafted HTTP request. As a result, the web interface crashes and is immediately restarted. The issue was fixed in RouterOS 6.49.10 stable. RouterOS version 7 is not affected.

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.

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 6.44.6 (long-term tree) suffers from an uncontrolled resource consumption vulnerability in the /nova/bin/cerm process. An authenticated remote attacker can cause a Denial of Service due to overloading the systems CPU.

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 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).

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) suffers from an assertion failure vulnerability in the /nova/bin/user process. An authenticated remote attacker can cause a Denial of Service due to an assertion failure via a crafted packet.

Mikrotik RouterOs before 6.47 (stable tree) suffers from a memory corruption vulnerability in the /nova/bin/dot1x process. An authenticated remote attacker can cause a Denial of Service (NULL pointer dereference).

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/lcdstat process. An authenticated remote attacker can cause a Denial of Service (NULL pointer dereference).

Mikrotik RouterOs before 6.47 (stable tree) suffers from a divison by zero vulnerability in the /nova/bin/lcdstat process. An authenticated remote attacker can cause a Denial of Service due to a divide by zero error.

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