When the affected device accepts this new IP configuration, a loss of communication occurs between the device and the rest of the system as the system traffic is still attempting to communicate with the device via the overwritten IP address.","published":"2018-12-07T14:29:01.000Z","lastModified":"2026-06-17T01:46:32.000Z","status":"Modified","sourceIdentifier":"ics-cert@hq.dhs.gov","cvss":{"version":"3.1","score":8.6,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H"},"cwe":["CWE-306"],"affected":["rockwellautomation/micrologix 1400 firmware","rockwellautomation/1756-enbt firmware","rockwellautomation/1756-eweb series a firmware","rockwellautomation/1756-eweb series b firmware","rockwellautomation/1756-en2f series a firmware","rockwellautomation/1756-en2f series b firmware","rockwellautomation/1756-en2f series c firmware","rockwellautomation/1756-en2t series a firmware","rockwellautomation/1756-en2t series b firmware","rockwellautomation/1756-en2t series c firmware","rockwellautomation/1756-en2t series d firmware","rockwellautomation/1756-en2tr series a firmware","rockwellautomation/1756-en2tr series b firmware","rockwellautomation/1756-en2tr series c firmware","rockwellautomation/1756-en3tr series a firmware","rockwellautomation/1756-en3tr series b firmware"],"epss":{"score":0.04335,"percentile":0.91148,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (4.33%).
