| CVE-2026-67277 | 1 Mikrotik | 1 Routeros | 2026-09-11 | N/A | 8.2 HIGH |
| 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-term), 7.23.4 (Long-term) and 7.24.2 (Stable) | |||||
| CVE-2026-86060 | 1 Mikrotik | 1 Routeros | 2026-09-11 | N/A | 9.8 CRITICAL |
| 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-2025-6443 | 1 Mikrotik | 1 Routeros | 2026-06-17 | N/A | 7.2 HIGH |
| 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 internal network. An attacker can leverage this vulnerability to gain access to internal network resources. Was ZDI-CAN-26415. | |||||
| CVE-2024-54952 | 1 Mikrotik | 1 Routeros | 2026-06-17 | N/A | 7.5 HIGH |
| MikroTik RouterOS 6.40.5, the SMB service contains a memory corruption vulnerability. Remote, unauthenticated attackers can exploit this issue by sending specially crafted packets, triggering a null pointer dereference. This leads to a Remote Denial of Service (DoS), rendering the SMB service unavailable. | |||||
| CVE-2024-54772 | 1 Mikrotik | 1 Routeros | 2026-06-17 | N/A | 5.4 MEDIUM |
| 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. | |||||

| CVE-2023-32154 | 1 Mikrotik | 1 Routeros | 2026-06-17 | N/A | 7.5 HIGH |
| 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. | |||||
| CVE-2023-30800 | 1 Mikrotik | 1 Routeros | 2026-06-17 | N/A | 7.5 HIGH |
| 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-2023-30799 | 1 Mikrotik | 1 Routeros | 2026-06-17 | N/A | 9.1 CRITICAL |
