It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-25667 in the wild and no public exploit code.\n\nAffected product: Siemens RUGGEDCOM RM1224. 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-2021-25667/ (Markdown: https://insights.sbomify.com/CVE-2021-25667/index.md)","id":"CVE-2021-25667","markdown":"https://insights.sbomify.com/CVE-2021-25667/index.md","name":"CVE-2021-25667","record":{"aliases":["GHSA-p672-97f8-chmq"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Siemens SCALANCE switch","requires_auth":"none","summary":"Remote attackers can cause denial of service or execute code via stack-based buffer overflow in STP BPDU handling on Siemens SCALANCE devices with passive listening enabled.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"ruggedcom_rm1224_firmware","vendor":"siemens"},{"product":"scalance_m-800_firmware","vendor":"siemens"},{"product":"scalance_s615_firmware","vendor":"siemens"},{"product":"scalance_sc622-2c_firmware","vendor":"siemens"},{"product":"scalance_sc632-2c_firmware","vendor":"siemens"},{"product":"scalance_sc636-2c_firmware","vendor":"siemens"},{"product":"scalance_sc642-2c_firmware","vendor":"siemens"},{"product":"scalance_sc646-2c_firmware","vendor":"siemens"},{"product":"scalance_x300wg_firmware","vendor":"siemens"},{"product":"scalance_xb-200_firmware","vendor":"siemens"},{"product":"scalance_xc-200_firmware","vendor":"siemens"},{"product":"scalance_xf-200ba_firmware","vendor":"siemens"},{"product":"scalance_xm400_firmware","vendor":"siemens"},{"product":"scalance_xp-200_firmware","vendor":"siemens"},{"product":"scalance_xr500_firmware","vendor":"siemens"}],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"A vulnerability has been identified in RUGGEDCOM RM1224 (All versions \u003e= V4.3 and \u003c V6.4), SCALANCE M-800 (All versions \u003e= V4.3 and \u003c V6.4), SCALANCE S615 (All versions \u003e= V4.3 and \u003c V6.4), SCALANCE SC-600 Family (All versions \u003e= V2.0 and \u003c V2.1.3), SCALANCE XB-200 (All versions \u003c V4.1), SCALANCE XC-200 (All versions \u003c V4.1), SCALANCE XF-200BA (All versions \u003c V4.1), SCALANCE XM400 (All versions \u003c V6.2), SCALANCE XP-200 (All versions \u003c V4.1), SCALANCE XR-300WG (All versions \u003c V4.1), SCALANCE XR500 (All versions \u003c V6.2).
