Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-27716 in the wild and no public exploit code.\n\nAffected product: KDDI CORPORATION HGW-BL1500HM. 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-2025-27716/ (Markdown: https://insights.sbomify.com/CVE-2025-27716/index.md)","id":"CVE-2025-27716","markdown":"https://insights.sbomify.com/CVE-2025-27716/index.md","name":"CVE-2025-27716","record":{"aliases":["GHSA-9x9g-g3c2-6rw9"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Home gateway router","requires_auth":"low_privilege","summary":"Attackers on the local network can read or modify files via path traversal in the USB storage sharing feature of the HGW-BL1500HM router.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Improper limitation of a pathname to a restricted directory ('Path Traversal') issue exists in the file/folder listing process of the USB storage file-sharing function of HGW-BL1500HM Ver 002.002.003 and earlier.
