Any signed-in user can exploit it over the network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-4144 and fix it if it is affected.\n\nWhat it is: CVE-2021-4144 is a high-severity command injection vulnerability in TP-LINK TL-WR802N V4(JP), published on 23 Dec 2021. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-4144 in the wild and no public exploit code.\n\nAffected product: TP-LINK TL-WR802N V4(JP). 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-2021-4144/ (Markdown: https://insights.sbomify.com/CVE-2021-4144/index.md)","id":"CVE-2021-4144","markdown":"https://insights.sbomify.com/CVE-2021-4144/index.md","name":"CVE-2021-4144","record":{"aliases":["GHSA-mhhg-695x-jq83"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"TP-Link WiFi router","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary OS commands on TP-Link TL-WR802N routers via OS command injection vulnerability.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"tl-wr802n_firmware","vendor":"tp-link"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/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":"TP-Link wifi router TL-WR802N V4(JP), with firmware version prior to 211202, is vulnerable to OS command injection.","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 TL-WR802N V4(JP)","id":"CVE-2021-4144","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Null dereference in QEMU","id":"CVE-2021-4145"},"packages":[],"prev":{"headline":"Cross-site Scripting (XSS) - Generic in bigbluebutton/bigbluebutton","id":"CVE-2021-4143"},"products":["TL-WR802N V4(JP)"],"published":"2021-12-23","related":[{"cvss_score":8.8,"headline":"Command injection in TL-WR802N","id":"CVE-2023-36489","kev_date_added":null,"published":"2023-09-06"},{"cvss_score":8.5,"headline":"Authenticated Command Injection on TP-Link TL-WR802N, TL-WR841N and TL-WR840N","id":"CVE-2026-3227","kev_date_added":null,"published":"2026-03-13"},{"cvss_score":8.1,"headline":"Memory corruption in n/a","id":"CVE-2021-29302","kev_date_added":null,"published":"2021-04-12"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["TP-LINK"]},"summary":"Attackers can execute arbitrary OS commands on TP-Link TL-WR802N routers via OS command injection vulnerability.","url":"https://insights.sbomify.com/CVE-2021-4144/"}
