{"schema":"threatline.record/2","record":{"id":"CVE-2026-104809","aliases":[],"summary":"Mitel MiVoice Office 400 Shared Object Hijacking Leading to Arbitrary Code Execution","details":"DigitalCanion has discovered a vulnerability that allows an attacker to cause the system to load an attacker-controlled .so file instead of the expected legitimate module. The loading mechanism relies on a predictable module name without adequately verifying the file’s origin or integrity. A malicious shared object using the expected name can therefore be loaded by a privileged process. The module code then executes within the context and privileges of that process. This results in arbitrary code execution and full compromise of the Mitel Linux virtual machine.","categories":["Applications & CMS"],"product":"Mitel MiVoice Office 400","vendor":"Mitel","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-104809","source_modified_at":"2026-10-05T12:55:24.978Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Mitel MiVoice Office 400","vendor":"Mitel","versions":[{"status":"affected","version":"11.0.96.0"}],"defaultStatus":"unknown"}],"fixed_versions":[],"cvss":8.4,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00087,"percentile":0.00323,"score_date":"2026-10-23"},"published_at":"2026-10-05T08:32:14.233Z","modified_at":"2026-10-05T12:55:24.978Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-104809","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-05T12:55:24.978Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-104809","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://digitalcanion.com/en/security-research/#vendor=mitel&status=cna"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-10-05T12:53:58.881891Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-05T12:55:24.978Z","content_hash":"ded2354439453bea137c9381aa17112c0db13f8b5f16448940fe250212164fa6"}}
