B2338-168, published on 22 Nov 2017. 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-2017-8156 in the wild and no public exploit code.\n\nAffected product: Huawei Technologies Co., Ltd. B2338-168. 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-2017-8156/ (Markdown: https://insights.sbomify.com/CVE-2017-8156/index.md)","id":"CVE-2017-8156","markdown":"https://insights.sbomify.com/CVE-2017-8156/index.md","name":"CVE-2017-8156","record":{"aliases":["GHSA-fvmw-hc2m-mr64"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Outdoor CPE unit","requires_auth":"none","summary":"An attacker with physical access can bypass authentication on the serial port to take control of the outdoor CPE unit.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"huawei","cpe":[{"product":"b2338-168_firmware","vendor":"huawei"}],"cvss":{"score":6.8,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"The outdoor unit of Customer Premise Equipment (CPE) product B2338-168 V100R001C00 has a no authentication vulnerability on the serial port.
