KEPServerEX uses OPC UA, a protocol which defines various object types that can be nested to create complex arrays. It does not implement a check to see if such an object is recursively defined, so an attack could send a maliciously created message that the decoder would try to decode until the stack overflowed and the device crashed.\n\n"}],"metrics":{"cvssMetricV31":[{"source":"ics-cert@hq.dhs.gov","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":3.6},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":3.6}]},"weaknesses":[{"source":"ics-cert@hq.dhs.gov","type":"Secondary","description":[{"lang":"en","value":"CWE-400"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-787"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:kepware:kepserverex:*:*:*:*:*:*:*:*","versionStartIncluding":"6.0.0","versionEndIncluding":"6.14.263","matchCriteriaId":"4BCC4117-EFB3-4627-941D-B105A539D986"}]}]}],"references":[{"url":"https://www.cisa.gov/news-events/ics-advisories/icsa-23-208-02","source":"ics-cert@hq.dhs.gov","tags":["Third Party Advisory","US Government Resource"]},{"url":"https://www.cisa.gov/news-events/ics-advisories/icsa-23-208-02","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Third Party Advisory","US Government Resource"]}]}}]}
