CVE-2025-42611

calendar_today October 6, 2026 domain routeros

An issue has been published regarding how RouterOS services decide which certificate authorities (CAs) to trust. Several RouterOS services, such as OpenVPN, CAPsMAN and Dot1X (802.1X), use certificates to verify who they are talking to. In affected versions these services all use the same system-wide certificate store, so any CA certificate that is trusted on the router is trusted by every service.
