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-2021-43421 exists.\n\nAffected packages and fixed versions:\n- studio-42/elfinder (Packagist): affected from 2.0.4; fixed in 2.1.60\n- studio-42/elfinder (Packagist): affected from 2.0.4; fixed in 2.1.60\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-2021-43421/ (Markdown: https://insights.sbomify.com/CVE-2021-43421/index.md)","id":"CVE-2021-43421","markdown":"https://insights.sbomify.com/CVE-2021-43421/index.md","name":"CVE-2021-43421","record":{"aliases":["GHSA-x4jx-hjwf-gc99"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"elFinder file manager","requires_auth":"none","summary":"Remote attackers can upload arbitrary files to execute PHP code in elFinder file manager libraries.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"elfinder","vendor":"std42"}],"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-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"A File Upload vulnerability exists in Studio-42 elFinder 2.0.4 to 2.1.59 via connector.minimal.php, which allows a remote malicious user to upload arbitrary files and execute PHP code.","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2021/CVE-2021-43421.yaml","stars":null,"title":"Studio-42 elFinder \u003c2.1.60 - Arbitrary File Upload"}],"tier":"weaponised"},"has_fix":true,"headline":"elFinder Unrestricted File Upload vulnerability","id":"CVE-2021-43421","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"file_upload","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"Denial of service in n/a","id":"CVE-2021-43429"},"packages":[{"ecosystem":"Packagist","fixed":["2.1.60"],"introduced":["2.0.4"],"last_affected":[],"package":"studio-42/elfinder","purl":null,"source":"GHSA-x4jx-hjwf-gc99"},{"ecosystem":"Packagist","fixed":["2.1.60"],"introduced":["2.0.4"],"last_affected":[],"package":"studio-42/elfinder","purl":"pkg:composer/studio-42/elfinder","source":"GHSA-x4jx-hjwf-gc99"}],"prev":{"headline":"SQL injection in n/a","id":"CVE-2021-43420"},"products":["n/a"],"published":"2022-04-07","related":[{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2023-52044","kev_date_added":null,"published":"2024-10-31"},{"cvss_score":9.8,"headline":"Studio 42 elFinder vulnerable to Incorrect Access Control","id":"CVE-2024-38909","kev_date_added":null,"published":"2024-07-30"},{"cvss_score":9.8,"headline":"RCE in Studio-42 elFinder on Windows before 2.1.61","id":"CVE-2022-27115","kev_date_added":null,"published":"2022-04-11"},{"cvss_score":9.8,"headline":"Multiple vulnerabilities leading to RCE","id":"CVE-2021-32682","kev_date_added":null,"published":"2021-06-14"},{"cvss_score":9.8,"headline":"elFinder command injection vulnerability in the PHP connector","id":"CVE-2019-9194","kev_date_added":null,"published":"2019-02-26"},{"cvss_score":9.1,"headline":"Path Traversal in Studio-42 elFinder through 2.1.60","id":"CVE-2022-26960","kev_date_added":null,"published":"2022-03-21"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Remote attackers can upload arbitrary files to execute PHP code in elFinder file manager libraries.","url":"https://insights.sbomify.com/CVE-2021-43421/"}
