{"id":"CVE-2018-7445","url":"https://www.cyber-defence.io/tools/cve/CVE-2018-7445","generatedAt":"2026-10-29T03:02:02.638Z","title":"MikroTik RouterOS Stack-Based Buffer Overflow Vulnerability","description":"A buffer overflow was found in the MikroTik RouterOS SMB service when processing NetBIOS session request messages. Remote attackers with access to the service can exploit this vulnerability and gain code execution on the system. The overflow occurs before authentication takes place, so it is possible for an unauthenticated remote attacker to exploit it. All architectures and all devices running RouterOS before versions 6.41.3/6.42rc27 are vulnerable.","published":"2018-03-19T21:29:01.000Z","lastModified":"2026-06-17T02:03:08.000Z","status":"Analyzed","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-119"],"affected":["mikrotik/routeros"],"epss":{"score":0.65828,"percentile":0.99265,"date":"2026-10-27","history":[{"date":"2026-10-25","score":0.65828,"percentile":0.99263}]},"kev":{"listed":true,"dateAdded":"2022-09-08","dueDate":"2022-09-29","knownRansomwareCampaignUse":"Unknown","notes":"Apply updates per vendor instructions.\nhttps://www.coresecurity.com/core-labs/advisories/mikrotik-routeros-smb-buffer-overflow#vendor_update, https://mikrotik.com/download; https://nvd.nist.gov/vuln/detail/CVE-2018-7445"},"exploits":{"count":1,"verified":false,"firstPublished":"2018-03-15","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":44290,"kind":"exploit","title":"MikroTik RouterOS < 6.41.3/6.42rc27 - SMB Buffer Overflow","url":"https://www.exploit-db.com/exploits/44290","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/hardware/remote/44290.py","file":"exploits/hardware/remote/44290.py","published":"2018-03-15","added":"2018-03-16","updated":"2018-03-16","author":"CoreLabs","type":"remote","platform":"hardware","port":null,"verified":false,"codes":["CVE-2018-7445"],"tags":null,"aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":"https://www.reddit.com/r/netsec/comments/84o6ki/mikrotik_routeros_smb_buffer_overflow/"}]},"verdict":{"level":"urgent","text":"Known to be exploited in the wild (CISA KEV, CISA remediation deadline 29 September 2022).
