It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-34860 and fix it if it is affected.\n\nWhat it is: CVE-2021-34860 is a medium-severity path traversal vulnerability in D-Link DAP-2020, published on 25 Oct 2021. 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-2021-34860 in the wild and no public exploit code.\n\nAffected product: D-Link DAP-2020. 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-2021-34860/ (Markdown: https://insights.sbomify.com/CVE-2021-34860/index.md)","id":"CVE-2021-34860","markdown":"https://insights.sbomify.com/CVE-2021-34860/index.md","name":"CVE-2021-34860","record":{"aliases":["GHSA-2w9j-55xj-gcp3"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"D-Link wireless router","requires_auth":"none","summary":"Network-adjacent attackers can exploit a path traversal flaw in the webproc endpoint to disclose sensitive information on D-Link DAP-2020 routers.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zdi","cpe":[{"product":"dap-2020_firmware","vendor":"dlink"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:A/AC:L/PR:N/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":"This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of D-Link DAP-2020 1.01rc001 routers.
