The SMB service in RouterOS 6 could be affected by a specially crafted SMB session setup packet. In the reported scenario, this could interrupt the active SMB session, which may also interrupt an ongoing file transfer that depends on that session.
This issue is fixed in RouterOS 6.49.14. RouterOS version 7 is not affected.
MikroTik always recommends keeping RouterOS devices up to date and using a strong firewall so SMB and other device services are not reachable from untrusted networks.
