An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-41653 exists.\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-2021-41653/ (Markdown: https://insights.sbomify.com/CVE-2021-41653/index.md)","id":"CVE-2021-41653","markdown":"https://insights.sbomify.com/CVE-2021-41653/index.md","name":"CVE-2021-41653","record":{"aliases":["GHSA-8fx7-hx38-cm88"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"TP-Link router","requires_auth":"none","summary":"Remote attackers can execute arbitrary code on TP-Link TL-WR840N routers by sending a crafted payload to the PING function.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"tl-wr840n_firmware","vendor":"tp-link"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"The PING function on the TP-Link TL-WR840N EU v5 router with firmware through TL-WR840N(EU)_V5_171211 is vulnerable to remote code execution via a crafted payload in an IP address input field.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2021-11-29","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":1,"refs":[{"date":"2021-11-29T06:39:43Z","kind":"github_poc","ref":"https://github.com/likeww/CVE-2021-41653","stars":0,"title":"TP-Link TL-WR840N EU v5 Remote Code Execution"},{"date":null,"kind":"nuclei","ref":"http/cves/2021/CVE-2021-41653.yaml","stars":null,"title":"TP-Link - OS Command Injection"}],"tier":"weaponised"},"has_fix":null,"headline":"Command injection in n/a","id":"CVE-2021-41653","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":"SQL injection in n/a","id":"CVE-2021-41654"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2021-41652"},"products":["n/a"],"published":"2021-11-13","related":[{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2022-25060","kev_date_added":null,"published":"2022-02-25"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2022-25061","kev_date_added":null,"published":"2022-02-25"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2022-25064","kev_date_added":null,"published":"2022-02-25"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2020-36178","kev_date_added":null,"published":"2021-01-06"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2018-11714","kev_date_added":null,"published":"2018-06-04"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2019-15060","kev_date_added":null,"published":"2019-08-22"}],"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":"attribution","licence":"MIT","name":"Nuclei templates"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-07-09","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code on TP-Link TL-WR840N routers by sending a crafted payload to the PING function.","url":"https://insights.sbomify.com/CVE-2021-41653/"}
