| CVE | Severity | CVSS | Published | Summary |
|---|---|---|---|---|
| CVE-2026-86060 | CRITICAL | 9.2 | Sep 5, 2026 | RouterOS contains an argument-handling flaw in the SSH login path involving usernames that begin with a prohibited character, allowing for the trusted RouterOS policy mask to be changed, leading to privilege escalation. Exploitation requires an unauthenticated SSH session to reach the RouterOS login helper.This issue was fixed in versions: 6.49.21 (Long-term), 7.23.4 (Long-term) and 7.24.2 (Stable) |
| CVE-2023-30799 | CRITICAL | 9.1 | Jul 19, 2023 | 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. |
| CVE-2026-67277 | HIGH | 8.8 | Sep 5, 2026 | RouterOS accepts a "related" btest connection before the corresponding primary session has completed authentication. An unauthenticated client can use this state to start an IPv4 UDP test. With "random-data=false", the sender transmits an uninitialized tail from a kernel packet buffer. A separate unchecked, inverted packet-size interval causes unsigned integer underflow, anomalously large fragmented output, and can restart the RouterOS kernel. This issue was fixed in versions: 6.49.21 (Long-t |
| CVE-2022-45313 | HIGH | 8.8 | Dec 5, 2022 | 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. |
| CVE-2021-41987 | HIGH | 8.1 | Mar 16, 2022 | In the SCEP Server of RouterOS in certain Mikrotik products, an attacker can trigger a heap-based buffer overflow that leads to remote code execution. The attacker must know the scep_server_name value. This affects RouterOS 6.46.8, 6.47.9, and 6.47.10. |
| CVE-2023-32154 | HIGH | 7.5 | May 3, 2024 | 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 leverag |
| CVE-2023-30800 | HIGH | 7.5 | Sep 7, 2023 | 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. |
| CVE-2020-20021 | HIGH | 7.5 | Jul 12, 2023 | An issue discovered in MikroTik Router v6.46.3 and earlier allows attacker to cause denial of service via misconfiguration in the SSH daemon. |
| CVE-2020-11881 | HIGH | 7.5 | Sep 14, 2020 | An array index error in MikroTik RouterOS 6.41.3 through 6.46.5, and 7.x through 7.0 Beta5, allows an unauthenticated remote attacker to crash the SMB server via modified setup-request packets, aka SUP-12964. |
| CVE-2018-5951 | HIGH | 7.5 | Mar 2, 2020 | 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. |
| CVE-2025-6443 | HIGH | 7.2 | Jun 25, 2025 | Mikrotik RouterOS VXLAN Source IP Improper Access Control Vulnerability. This vulnerability allows remote attackers to bypass access restrictions on affected installations of Mikrotik RouterOS. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of remote IP addresses when processing VXLAN traffic. The issue results from the lack of validation of the remote IP address against configured values prior to allowing ingress traffic into the inte |
| CVE-2026-67279 | MEDIUM | 6.9 | Sep 5, 2026 | RouterOS SSH enters the connection protocol after a client-requested rekey even though user authentication was never attempted, allowing an unauthenticated client to open a session channel and send an exec request. On affected builds the server dispatches the command, enabling unauthenticated creation, overwrite, and reconstruction of files in the RouterOS managed file namespace, including support files containing configuration and diagnostic data.This issue was fixed in versions: 6.49.21 (Long- |
| CVE-2022-36522 | MEDIUM | 6.5 | Aug 26, 2022 | 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. |
| CVE-2021-36614 | MEDIUM | 6.5 | May 11, 2022 | 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). |
| CVE-2021-36613 | MEDIUM | 6.5 | May 11, 2022 | 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). |
| CVE-2020-20262 | MEDIUM | 6.5 | Jul 21, 2021 | 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. |
| CVE-2020-20249 | MEDIUM | 6.5 | Jul 19, 2021 | 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. |
| CVE-2020-20230 | MEDIUM | 6.5 | Jul 19, 2021 | 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. |
| CVE-2020-20231 | MEDIUM | 6.5 | Jul 14, 2021 | 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). |
