An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-17407 in the wild and no public exploit code.\n\nAffected product: Microhard Bullet-LTE. 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-2020-17407/ (Markdown: https://insights.sbomify.com/CVE-2020-17407/index.md)","id":"CVE-2020-17407","markdown":"https://insights.sbomify.com/CVE-2020-17407/index.md","name":"CVE-2020-17407","record":{"aliases":["GHSA-hpgj-wfpp-wx53"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"LTE network device","requires_auth":"none","summary":"Remote attackers can execute arbitrary code with root privileges on Microhard Bullet-LTE devices via a stack-based buffer overflow in authentication header handling.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zdi","cpe":[{"product":"bullet-lte_firmware","vendor":"microhardcorp"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"This vulnerability allows remote attackers to execute arbitrary code on affected installations of Microhard Bullet-LTE prior to v1.2.0-r1112.
