{"id":"CVE-2026-27843","state":"PUBLISHED","title":"SenseLive X3050 Missing authentication for critical function","description":"A vulnerability exists in SenseLive X3050's web management interface that allows critical configuration parameters to be modified without sufficient authentication or server-side validation. By applying unsupported or disruptive values to recovery mechanisms and network settings, an attacker can induce a persistent lockout state. Because the device lacks a physical reset button, recovery requires specialized technical access via the console to perform a factory reset, resulting in a total denial-of-service for the gateway and its connected RS-485 downstream systems.","publishedAt":"2026-04-23T23:54:55.051Z","updatedAt":"2026-04-24T13:10:40.862Z","severity":{"score":9.2,"label":"Critical","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:H","source":"icscert"},"assigner":"icscert","products":["SenseLive X3050"],"affected":[{"vendor":"SenseLive","product":"X3050","defaultStatus":"unaffected","versions":[{"version":"V1.523","status":"affected"}]}],"references":["https://senselive.io/contact","https://www.cisa.gov/news-events/ics-advisories/icsa-26-111-12","https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2026/icsa-26-111-12.json"],"weaknesses":["CWE-306"],"ingestedAt":"2026-10-29T20:11:31.369Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/27xxx/CVE-2026-27843.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-27843","state":"PUBLISHED","datePublished":"2026-04-23T23:54:55.051Z","dateUpdated":"2026-04-24T13:10:40.862Z","assignerShortName":"icscert","assignerOrgId":"7d14cffa-0d7d-4270-9dc0-52cabd5a23a6","dateReserved":"2026-04-14T16:05:54.167Z"},"containers":{"cna":{"title":"SenseLive X3050 Missing authentication for critical function","descriptions":[{"lang":"en","value":"A vulnerability exists in SenseLive X3050's web management interface that allows critical configuration parameters to be modified without sufficient authentication or server-side validation.
