{"schemaVersion":3,"id":"CVE-2026-78556","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"A vulnerability has been identified in Industrial Edge App Publisher (All versions < V1.27.9). The affected software does not properly validate the server certificate when initiating a TLS connection. This allows an attacker to intercept and relay communication (Man-in-the-Middle attack) and to spoof a trusted entity by interfering in the communication path between the client and the intended server.","dates":{"published":"2026-10-13T09:18:55.291Z","modified":"2026-10-16T17:18:08.808Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.6,"severity":"high","version":"4.0","versionLabel":"v4.0","source":"CVE.org","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"4.0","versionLabel":"v4.0","source":"CVE.org","score":7.6,"severity":"high","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":7.4,"severity":"high","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","exploitability":null,"impact":null,"computed":false},{"version":"4.0","versionLabel":"v4.0","source":"NVD","score":7.6,"severity":"high","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":7.4,"severity":"high","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00213,"percentile":0.10843,"severity":"low","asOf":"2026-10-18T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-14T00:00:00.000Z","score":0.00213,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00213,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00213,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00213,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00213,"percentile":0.10843}],"last30":[{"date":"2026-10-14T00:00:00.000Z","score":0.00213,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00213,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00213,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00213,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00213,"percentile":0.10843}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-295","name":"Improper Certificate Validation","description":"The product does not validate, or incorrectly validates, a certificate.","type":"weakness","status":"Draft","abstraction":"Base","likelihoodOfExploit":null,"url":"https://cwe.mitre.org/data/definitions/295.html"}],"affected":[{"vendor":"siemens","product":"industrial edge app publisher","name":"Industrial Edge App Publisher","label":"industrial edge app publisher","ecosystem":null,"cpePart":"a","purl":null,"purlType":null,"versions":[{"text":"< V1.27.9","noFixRecorded":false,"fixedIn":null}],"versionsText":"< V1.27.9","eol":null,"hubHref":"/vendor/siemens/industrial_edge_app_publisher"}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://cert-portal.siemens.com/productcert/html/ssa-968435.html","label":"cert-portal.siemens.com/productcert/html/ssa-968435.html","hostname":"cert-portal.siemens.com","tags":[]}],"lineage":{"upstream":[],"downstream":[],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2026-10-13T09:18:55.291Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-10-16T17:18:08.808Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":30,"level":"medium","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-19T02:38:55.722Z","stale":false,"partial":false}}
