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-2022-43648 and fix it if it is affected.\n\nWhat it is: CVE-2022-43648 is a high-severity memory corruption vulnerability in D-Link DIR-3040, published on 29 Mar 2023. 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-2022-43648 in the wild and no public exploit code.\n\nAffected product: D-Link DIR-3040. 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-2022-43648/ (Markdown: https://insights.sbomify.com/CVE-2022-43648/index.md)","id":"CVE-2022-43648","markdown":"https://insights.sbomify.com/CVE-2022-43648/index.md","name":"CVE-2022-43648","record":{"aliases":["GHSA-p682-rxp7-r33h"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"D-Link router","requires_auth":"none","summary":"Network-adjacent attackers can execute arbitrary code on D-Link DIR-3040 routers via a heap buffer overflow in the MiniDLNA service without authentication.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zdi","cpe":[{"product":"dir-3040_firmware","vendor":"dlink"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DIR-3040 1.20B03 routers.
