The _log() function in src/mikrotik_plugin/fastnetmon_mikrotik.php (lines 107-108) constructs shell commands by concatenating the $msg parameter directly into exec() calls: exec(\"echo `date` \\\"- {FASTNETMON] - \" . $msg . \" \\\" >> \" . $FILE_LOG_TMP). This is identical in pattern to the Juniper plugin vulnerability. The $msg variable contains unsanitized attack data from command-line arguments. An attacker who can influence argv[] values can inject arbitrary shell commands. The fix is to replace exec() with file_put_contents() or use escapeshellarg()."}],"affected":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}],"references":[{"url":"https://github.com/pavel-odintsov/fastnetmon"},{"url":"https://github.com/pavel-odintsov/fastnetmon/blob/master/src/mikrotik_plugin/fastnetmon_mikrotik.php"},{"url":"https://lorikeetsecurity.com/blog/fastnetmon-cve-2026-48695-mikrotik-cmd-injection"}],"problemTypes":[{"descriptions":[{"type":"text","lang":"en","description":"n/a"}]}]},"adp":[{"problemTypes":[{"descriptions":[{"type":"CWE","cweId":"CWE-78","lang":"en","description":"CWE-78 Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')"}]}],"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":8.1,"attackVector":"NETWORK","baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","integrityImpact":"HIGH","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"NONE","privilegesRequired":"LOW","confidentialityImpact":"HIGH"}},{"other":{"type":"ssvc","content":{"timestamp":"2026-05-26T20:17:29.930336Z","id":"CVE-2026-48695","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-05-26T20:17:41.811Z"}}]},"dataVersion":"5.2"}
