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-2024-21821 and fix it if it is affected.\n\nWhat it is: CVE-2024-21821 is a high-severity command injection vulnerability in TP-Link Archer AX3000, published on 10 Jan 2024. 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-2024-21821 in the wild and no public exploit code.\n\nAffected product: TP-Link Archer AX3000. 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-2024-21821/ (Markdown: https://insights.sbomify.com/CVE-2024-21821/index.md)","id":"CVE-2024-21821","markdown":"https://insights.sbomify.com/CVE-2024-21821/index.md","name":"CVE-2024-21821","record":{"aliases":["GHSA-wqqq-355c-2q6w"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"TP-Link router","requires_auth":"low_privilege","summary":"Authenticated network-adjacent attackers can execute arbitrary OS commands on TP-Link routers via the LAN or Wi-Fi interface.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"archer_ax3000_firmware","vendor":"tp-link"},{"product":"archer_ax5400_firmware","vendor":"tp-link"},{"product":"archer_axe75_firmware","vendor":"tp-link"}],"cvss":{"score":8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"Multiple TP-LINK products allow a network-adjacent authenticated attacker with access to the product from the LAN port or Wi-Fi to execute arbitrary OS commands.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Command injection in Archer AX3000","id":"CVE-2024-21821","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2024"},"n_packages":0,"n_references":5,"next":{"headline":"Privilege escalation in Intel(R) DSA and Intel(R) IAA for some Intel(R) 4th or 5th generation Xeon(R) processors","id":"CVE-2024-21823"},"packages":[],"prev":{"headline":"Privilege escalation in Intel(R) Xeon(R) processor memory controller configurations when using Intel(R) SGX","id":"CVE-2024-21820"},"products":["Archer AX3000","Archer AX5400","Archer AXE75","Archer Air R5"],"published":"2024-01-10","related":[{"cvss_score":8.8,"headline":"Command injection in Archer AX3000","id":"CVE-2024-21773","kev_date_added":null,"published":"2024-01-10"},{"cvss_score":8.8,"headline":"Command injection in Archer AX3000","id":"CVE-2024-21833","kev_date_added":null,"published":"2024-01-10"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-06-17","vendors":["TP-Link"]},"summary":"Authenticated network-adjacent attackers can execute arbitrary OS commands on TP-Link routers via the LAN or Wi-Fi interface.","url":"https://insights.sbomify.com/CVE-2024-21821/"}
