Senserva AI Opinion for CVE-2018-7445
MikroTik RouterOS crashes into remote code execution when it parses malicious NetBIOS session request messages, a stack buffer overflow rated Critical Severity at CVSS 9.8. MikroTik routers are deployed in the millions at small sites and ISPs, patched rarely, and already prized by botnet builders, so the 61 percent EPSS score and KEV listing fit the pattern. A compromised edge router lets attackers intercept and redirect all site traffic.
Do this: Upgrade RouterOS on all MikroTik devices and block NetBIOS service access from untrusted networks.
