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-2023-27355 in the wild and no public exploit code.\n\nAffected product: Sonos One Speaker. 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-2023-27355/ (Markdown: https://insights.sbomify.com/CVE-2023-27355/index.md)","id":"CVE-2023-27355","markdown":"https://insights.sbomify.com/CVE-2023-27355/index.md","name":"CVE-2023-27355","record":{"aliases":["GHSA-h7xj-6mw4-67wx"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Sonos smart speaker","requires_auth":"none","summary":"Network-adjacent attackers can execute arbitrary code with root privileges via a stack buffer overflow in the MPEG-TS parser.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zdi","cpe":[{"product":"one_firmware","vendor":"sonos"},{"product":"s1","vendor":"sonos"},{"product":"s2","vendor":"sonos"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:A/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 network-adjacent attackers to execute arbitrary code on affected installations of Sonos One Speaker 70.3-35220.
