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-2022-43972 and fix it if it is affected.\n\nWhat it is: CVE-2022-43972 is a medium-severity vulnerability in Linksys WRT54GL Wireless-G Broadband Router, published on 9 Jan 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-2022-43972 in the wild and no public exploit code.\n\nAffected product: Linksys WRT54GL Wireless-G Broadband Router. 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-2022-43972/ (Markdown: https://insights.sbomify.com/CVE-2022-43972/index.md)","id":"CVE-2022-43972","markdown":"https://insights.sbomify.com/CVE-2022-43972/index.md","name":"CVE-2022-43972","record":{"aliases":["GHSA-2p3f-3cj6-r8vv"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linksys wireless router","requires_auth":"none","summary":"An unauthenticated attacker can cause a denial of service on Linksys WRT54GL routers by triggering a null pointer dereference in the UPnP service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"trellix","cpe":[{"product":"wrt54gl_firmware","vendor":"linksys"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"A null pointer dereference vulnerability exists in Linksys WRT54GL Wireless-G Broadband Router with firmware \u003c= 4.30.18.006.
