An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-5347 exists.\n\nAffected product: Korenix JetNet Series. 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-2023-5347/ (Markdown: https://insights.sbomify.com/CVE-2023-5347/index.md)","id":"CVE-2023-5347","markdown":"https://insights.sbomify.com/CVE-2023-5347/index.md","name":"CVE-2023-5347","record":{"aliases":["GHSA-3fr9-8m46-r2mm"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Korenix JetNet","requires_auth":"none","summary":"Attackers can bypass signature verification to install malicious firmware on Korenix JetNet devices, gaining full control.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CyberDanube","cpe":[{"product":"jetnet_4508-w_firmware","vendor":"korenix"},{"product":"jetnet_4508_firmware","vendor":"korenix"},{"product":"jetnet_4508f-m_firmware","vendor":"korenix"},{"product":"jetnet_4508f-mw_firmware","vendor":"korenix"},{"product":"jetnet_4508f-s_firmware","vendor":"korenix"},{"product":"jetnet_4508f-sw_firmware","vendor":"korenix"},{"product":"jetnet_4508i-w_firmware","vendor":"korenix"},{"product":"jetnet_4508if-m_firmware","vendor":"korenix"},{"product":"jetnet_4508if-mw_firmware","vendor":"korenix"},{"product":"jetnet_4508if-s_firmware","vendor":"korenix"},{"product":"jetnet_4508if-sw_firmware","vendor":"korenix"},{"product":"jetnet_5310g_firmware","vendor":"korenix"},{"product":"jetnet_5612g-4f_firmware","vendor":"korenix"},{"product":"jetnet_5612gp-4f_firmware","vendor":"korenix"},{"product":"jetnet_5620g-4c_firmware","vendor":"korenix"},{"product":"jetnet_5728g-24p-ac-2dc-eu_firmware","vendor":"korenix"},{"product":"jetnet_5728g-24p-ac-2dc-us_firmware","vendor":"korenix"},{"product":"jetnet_6528gf-2ac-eu_firmware","vendor":"korenix"},{"product":"jetnet_6528gf-2ac-us_firmware","vendor":"korenix"},{"product":"jetnet_6528gf-2dc24_firmware","vendor":"korenix"},{"product":"jetnet_6528gf-2dc48_firmware","vendor":"korenix"},{"product":"jetnet_6528gf-ac-eu_firmware","vendor":"korenix"},{"product":"jetnet_6528gf-ac-us_firmware","vendor":"korenix"},{"product":"jetnet_6628x-4f-eu_firmware","vendor":"korenix"},{"product":"jetnet_6628xp-4f-us_firmware","vendor":"korenix"},{"product":"jetnet_6728g-24p-ac-2dc-eu_firmware","vendor":"korenix"},{"product":"jetnet_6728g-24p-ac-2dc-us_firmware","vendor":"korenix"},{"product":"jetnet_6828gf-2ac-au_firmware","vendor":"korenix"},{"product":"jetnet_6828gf-2ac-eu_firmware","vendor":"korenix"},{"product":"jetnet_6828gf-2ac-us_firmware","vendor":"korenix"},{"product":"jetnet_6828gf-2dc24_firmware","vendor":"korenix"},{"product":"jetnet_6828gf-2dc48_firmware","vendor":"korenix"},{"product":"jetnet_6828gf-ac-dc24-eu_firmware","vendor":"korenix"},{"product":"jetnet_6828gf-ac-dc24-us_firmware","vendor":"korenix"},{"product":"jetnet_6828gf-ac-us_firmware","vendor":"korenix"},{"product":"jetnet_6910g-m12_hvdc_firmware","vendor":"korenix"},{"product":"jetnet_7310g-v2_firmware","vendor":"korenix"},{"product":"jetnet_7628x-4f-eu_firmware","vendor":"korenix"},{"product":"jetnet_7628x-4f-us_firmware","vendor":"korenix"},{"product":"jetnet_7628xp-4f-eu_firmware","vendor":"korenix"},{"product":"jetnet_7628xp-4f-us_firmware","vendor":"korenix"},{"product":"jetnet_7714g-m12_hvdc_firmware","vendor":"korenix"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"},{"id":"CWE-327","name":"Use of a Broken or Risky Cryptographic Algorithm"}],"description":"An Improper Verification of Cryptographic Signature vulnerability in the update process of Korenix JetNet Series allows replacing the whole operating system including Trusted Executables. This issue affects JetNet devices older than firmware version 2024/01.","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 Firmware Upgrade","id":"CVE-2023-5347","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2023"},"n_packages":0,"n_references":4,"next":{"headline":"Product Catalog Enquiry for WooCommerce \u003c 5.0.3 -
