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-2023-1261 in the wild and no public exploit code.\n\nAffected product: silabs.com Wi-SUN SDK. 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-2023-1261/ (Markdown: https://insights.sbomify.com/CVE-2023-1261/index.md)","id":"CVE-2023-1261","markdown":"https://insights.sbomify.com/CVE-2023-1261/index.md","name":"CVE-2023-1261","record":{"aliases":["GHSA-8cf7-2x37-pgq8"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Wi-SUN SDK","requires_auth":"none","summary":"A missing MAC layer security check in the Wi-SUN SDK allows malicious nodes to route unauthorized messages through the network.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Silabs","cpe":[{"product":"wi-sun_software_development_kit","vendor":"silabs"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"Missing MAC layer security in Silicon Labs Wi-SUN SDK v1.5.0 and earlier allows malicious node to route malicious messages through network.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Missing MAC layer security in Wi-SUN SDK","id":"CVE-2023-1261","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"Missing MAC layer security in Wi-SUN Linux Border Router","id":"CVE-2023-1262"},"packages":[],"prev":{"headline":"Kube-apiserver: privesc","id":"CVE-2023-1260"},"products":["Wi-SUN SDK"],"published":"2023-03-21","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-02-26","vendors":["silabs.com"]},"summary":"A missing MAC layer security check in the Wi-SUN SDK allows malicious nodes to route unauthorized messages through the network.","url":"https://insights.sbomify.com/CVE-2023-1261/"}
