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-2021-35004 and fix it if it is affected.\n\nWhat it is: CVE-2021-35004 is a high-severity memory corruption vulnerability in TP-Link TL-WA1201, published on 21 Jan 2022. 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-2021-35004 in the wild and no public exploit code.\n\nAffected product: TP-Link TL-WA1201. 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-2021-35004/ (Markdown: https://insights.sbomify.com/CVE-2021-35004/index.md)","id":"CVE-2021-35004","markdown":"https://insights.sbomify.com/CVE-2021-35004/index.md","name":"CVE-2021-35004","record":{"aliases":["GHSA-cqp4-9vc9-xvcp"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Wireless access point","requires_auth":"none","summary":"Remote attackers can execute arbitrary code as root on TP-Link wireless access points via a stack-based buffer overflow in DNS response handling without authentication.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zdi","cpe":[{"product":"tl-wa1201_firmware","vendor":"tp-link"}],"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-121","name":"Stack-based Buffer Overflow"}],"description":"This vulnerability allows remote attackers to execute arbitrary code on affected installations of TP-Link TL-WA1201 1.0.1 Build 20200709 rel.66244(5553) wireless access points.
