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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","score":8.6},"cwes":["CWE-306"],"references":["http://www.securityfocus.com/bid/106132","https://ics-cert.us-cert.gov/advisories/ICSA-18-310-02","http://www.securityfocus.com/bid/106132","https://ics-cert.us-cert.gov/advisories/ICSA-18-310-02"],"products":["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","rockwellautomation:1756-enbt_firmware","rockwellautomation:1756-eweb_series_a_firmware","rockwellautomation:1756-eweb_series_b_firmware","rockwellautomation:micrologix_1400_firmware"],"source":"nvd","synced_at":"2026-10-19T20:54:36.112582389+00:00"},"epss":{"cve":"CVE-2018-17924","score":0.05845,"percentile":0.93176,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
