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-2020-28395 in the wild and no public exploit code.\n\nAffected product: Siemens SCALANCE X-200RNA switch family. 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-2020-28395/ (Markdown: https://insights.sbomify.com/CVE-2020-28395/index.md)","id":"CVE-2020-28395","markdown":"https://insights.sbomify.com/CVE-2020-28395/index.md","name":"CVE-2020-28395","record":{"aliases":["GHSA-vfw8-4p7f-cjjh"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens SCALANCE switch","requires_auth":"none","summary":"Attackers can decrypt previously captured traffic and perform man-in-the-middle attacks because devices reuse private keys after factory resets.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"scalance_xr324-12m_firmware","vendor":"siemens"},{"product":"scalance_xr324-12m_ts_firmware","vendor":"siemens"},{"product":"scalance_xr324-4m_eec_firmware","vendor":"siemens"},{"product":"scalance_xr324-4m_poe_firmware","vendor":"siemens"},{"product":"scalance_xr324-4m_poe_ts_firmware","vendor":"siemens"},{"product":"scalance_xr324wg_firmware","vendor":"siemens"},{"product":"scalance_xr326-2c_poe_wg_firmware","vendor":"siemens"},{"product":"scalance_xr328-4c_wg_firmware","vendor":"siemens"}],"cvss":{"score":5.9,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-798","name":"Use of Hard-coded Credentials"},{"id":"CWE-321","name":"Use of Hard-coded Cryptographic Key"}],"description":"A vulnerability has been identified in SCALANCE X-200RNA switch family (All versions \u003c V3.2.7), SCALANCE X-300 switch family (incl.
