An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-104805 in the wild and no public exploit code.\n\nAffected product: Mitel MiVoice Office 400. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-104805/ (Markdown: https://insights.sbomify.com/CVE-2026-104805/index.md)","id":"CVE-2026-104805","markdown":"https://insights.sbomify.com/CVE-2026-104805/index.md","name":"CVE-2026-104805","record":{"aliases":["GHSA-vh23-h9qx-6q3f"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"VoIP PBX system","requires_auth":"high_privilege","summary":"An attacker with backup repository access can upload a malicious archive to achieve root code execution on the Mitel MiVoice Office 400 system.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"NCSC.ch","cpe":[],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:P/AU:Y/R:U/V:D/RE:M/U:Amber","version":"4.0"},"cwes":[{"id":"CWE-494","name":"Download of Code Without Integrity Check"},{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"},{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"},{"id":"CWE-73","name":"External Control of File Name or Path"},{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"DigitalCanion has discovered a vulnerability in the backup restoration functionality that allows an attacker with access to the configured backup repository to introduce arbitrary files into the system during restoration.\n\nThe specific flaw exists within the backup restoration mechanism, which fails to properly validate the paths, file types, integrity, and authenticity of files contained within a restored TGZ archive. The application does not perform file-signature verification before extracting the archive, allowing a specially crafted backup to contain attacker-controlled files.\n\nAn attacker with access to the backup SFTP or other configured repository can therefore provide a malicious TGZ archive that, when restored by the system, may place arbitrary files on the underlying Linux system. Depending on the location and permissions of the extracted files, this behavior can potentially be leveraged to achieve arbitrary code execution with root privileges and compromise the underlying virtual machine.\n\nThe absence of enforced backup passwords further reduces the protection provided by the backup mechanism and may facilitate unauthorized access to the repository.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Mitel MiVoice Office 400 Backup Restoration Arbitrary File Write Leading to Root Code Execution","id":"CVE-2026-104805","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Mitel MiVoice Office 400 System Logs Path Traversal Information Disclosure","id":"CVE-2026-104806"},"packages":[],"prev":{"headline":"Auth bypass in WPCOM Member","id":"CVE-2026-104803"},"products":["Mitel MiVoice Office 400"],"published":"2026-10-05","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-05","vendors":["Mitel"]},"summary":"An attacker with backup repository access can upload a malicious archive to achieve root code execution on the Mitel MiVoice Office 400 system.","url":"https://insights.sbomify.com/CVE-2026-104805/"}
