Summary
A memory corruption vulnerability has been discovered in the SMB service of MikroTik RouterOS. Remote, unauthenticated attackers can exploit this issue by sending specially crafted packets to the SMB service, triggering a null pointer dereference.
This results in a remote denial of service (DoS) condition, rendering the SMB service unavailable. Users are advised to upgrade to the latest RouterOS 7.x stable release to address this vulnerability.
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.
