An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-29516 in the wild and no public exploit code.\n\nAffected product: Buffalo TeraStation NAS TS5400R. 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-2026-29516/ (Markdown: https://insights.sbomify.com/CVE-2026-29516/index.md)","id":"CVE-2026-29516","markdown":"https://insights.sbomify.com/CVE-2026-29516/index.md","name":"CVE-2026-29516","record":{"aliases":["GHSA-p4fh-pgj9-w5xq"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Buffalo TeraStation NAS","requires_auth":"high_privilege","summary":"Authenticated attackers can read the /etc/shadow file to retrieve hashed passwords due to excessive file permissions on Buffalo TeraStation NAS devices.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"terastation_nas_ts5400r_firmware","vendor":"buffaloamericas"}],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-732","name":"Incorrect Permission Assignment for Critical Resource"}],"description":"Buffalo TeraStation NAS TS5400R firmware version 4.02-0.06 and prior contain an excessive file permissions vulnerability that allows authenticated attackers to read the /etc/shadow file by uploading and executing a PHP file through the webserver.
