Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-44827 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-44827/ (Markdown: https://insights.sbomify.com/CVE-2021-44827/index.md)","id":"CVE-2021-44827","markdown":"https://insights.sbomify.com/CVE-2021-44827/index.md","name":"CVE-2021-44827","record":{"aliases":["GHSA-m37g-hc3h-jpg8"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"TP-Link Archer C20i","requires_auth":"low_privilege","summary":"Remote authenticated attackers can execute arbitrary OS commands with root privileges via the X_TP_ExternalIPv6Address parameter on TP-Link Archer C20i routers.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"archer_c20i_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":"There is remote authenticated OS command injection on TP-Link Archer C20i 0.9.1 3.2 v003a.0 Build 170221 Rel.55462n devices vie the X_TP_ExternalIPv6Address HTTP parameter, allowing a remote attacker to run arbitrary commands on the router with root privileges.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2021-12-13","github_poc":1,"max_poc_stars":4,"metasploit":0,"nuclei":0,"refs":[{"date":"2021-12-13T11:17:12Z","kind":"github_poc","ref":"https://github.com/full-disclosure/CVE-2021-44827","stars":4,"title":"A PoC for CVE-2021-44827 - authenticated remote code execution in Tp-link Archer C20i"}],"tier":"poc_unverified"},"has_fix":null,"headline":"Command injection in n/a","id":"CVE-2021-44827","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"Memory corruption in n/a","id":"CVE-2021-44828"},"packages":[],"prev":{"headline":"Modifying User Permissions via Unauthorized Access in Single Connect","id":"CVE-2021-44795"},"products":["n/a"],"published":"2022-03-04","related":[],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Remote authenticated attackers can execute arbitrary OS commands with root privileges via the X_TP_ExternalIPv6Address parameter on TP-Link Archer C20i routers.","url":"https://insights.sbomify.com/CVE-2021-44827/"}
