{"id":"CVE-2026-104809","state":"PUBLISHED","title":"Mitel MiVoice Office 400 Shared Object Hijacking Leading to Arbitrary Code Execution","description":"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.","publishedAt":"2026-10-05T08:32:14.233Z","updatedAt":"2026-10-05T12:55:24.978Z","severity":{"score":8.4,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:P/AU:Y/U:Amber","source":"NCSC.ch"},"assigner":"NCSC.ch","products":["Mitel Mitel MiVoice Office 400"],"affected":[{"vendor":"Mitel","product":"Mitel MiVoice Office 400","defaultStatus":"unknown","versions":[{"version":"11.0.96.0","status":"affected"}],"platforms":["Linux"]}],"references":["https://digitalcanion.com/en/security-research/#vendor=mitel&status=cna"],"weaknesses":["CWE-73","CWE-494","CWE-829","CWE-426","CWE-427"],"ingestedAt":"2026-10-29T20:10:23.711Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/104xxx/CVE-2026-104809.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-104809","state":"PUBLISHED","datePublished":"2026-10-05T08:32:14.233Z","dateUpdated":"2026-10-05T12:55:24.978Z","assignerShortName":"NCSC.ch","assignerOrgId":"455daabc-a392-441d-aa46-37d35189897c","dateReserved":"2026-10-02T13:47:47.693Z"},"containers":{"cna":{"title":"Mitel MiVoice Office 400 Shared Object Hijacking Leading to Arbitrary Code Execution","descriptions":[{"lang":"en","value":"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.
