It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-43478 exists.\n\nAffected product: Telstra Smart Modem Gen 2 (Arcadyan LH1000). 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-2023-43478/ (Markdown: https://insights.sbomify.com/CVE-2023-43478/index.md)","id":"CVE-2023-43478","markdown":"https://insights.sbomify.com/CVE-2023-43478/index.md","name":"CVE-2023-43478","record":{"aliases":["GHSA-x2v2-mj6c-wfp3"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Telstra Smart Modem","requires_auth":"none","summary":"Unauthenticated attackers can upload malicious firmware or configurations to the Telstra Smart Modem, leading to root code execution.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"arcadyan_lh1000_firmware","vendor":"telstra"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"fake_upload.cgi on the Telstra Smart Modem Gen 2 (Arcadyan LH1000), firmware versions \u003c 0.18.15r, allows unauthenticated attackers to upload firmware images and configuration backups, which could allow them to alter the firmware or the configuration on the device, ultimately leading to code execution as root.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Unauthenticated configuration restore and firmware update","id":"CVE-2023-43478","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Code injection in n/a","id":"CVE-2023-43481"},"packages":[],"prev":{"headline":"Post-Auth Command Injection in Telstra Smart Modem Gen 2 (Arcadyan LH1000)","id":"CVE-2023-43477"},"products":["Smart Modem Gen 2 (Arcadyan LH1000)"],"published":"2023-09-20","related":[{"cvss_score":6.8,"headline":"Post-Auth Command Injection in Telstra Smart Modem Gen 2 (Arcadyan LH1000)","id":"CVE-2023-43477","kev_date_added":null,"published":"2023-09-20"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-09-24","vendors":["Telstra"]},"summary":"Unauthenticated attackers can upload malicious firmware or configurations to the Telstra Smart Modem, leading to root code execution.","url":"https://insights.sbomify.com/CVE-2023-43478/"}
