An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-21322 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- feehi/cms (Packagist): affected all versions; fixed in 2.0.8.1\n- feehi/cms (Packagist): affected all versions; fixed in 2.0.8.1\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-2020-21322/ (Markdown: https://insights.sbomify.com/CVE-2020-21322/index.md)","id":"CVE-2020-21322","markdown":"https://insights.sbomify.com/CVE-2020-21322/index.md","name":"CVE-2020-21322","record":{"aliases":["GHSA-rf3w-29h3-r636"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Feehi CMS","requires_auth":"none","summary":"Attackers can execute arbitrary code by uploading a crafted PHP file to Feehi CMS, requiring immediate upgrade.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"feehicms","vendor":"feehi"}],"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":"An arbitrary file upload vulnerability in Feehi CMS v2.0.8 and below allows attackers to execute arbitrary code via a crafted PHP file.","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Arbitrary Code Execution in feehi/cms","id":"CVE-2020-21322","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"file_upload","year":"2020"},"n_packages":2,"n_references":1,"next":{"headline":"File upload in n/a","id":"CVE-2020-21325"},"packages":[{"ecosystem":"Packagist","fixed":["2.0.8.1"],"introduced":["0"],"last_affected":[],"package":"feehi/cms","purl":null,"source":"GHSA-rf3w-29h3-r636"},{"ecosystem":"Packagist","fixed":["2.0.8.1"],"introduced":["0"],"last_affected":[],"package":"feehi/cms","purl":"pkg:composer/feehi/cms","source":"GHSA-rf3w-29h3-r636"}],"prev":{"headline":"Cross-site request forgery in n/a","id":"CVE-2020-21321"},"products":["n/a"],"published":"2021-09-15","related":[{"cvss_score":9.8,"headline":"liufee CMS File Upload vulnerability","id":"CVE-2020-21174","kev_date_added":null,"published":"2023-06-20"},{"cvss_score":9.8,"headline":"Liufee CMS File Upload vulnerability","id":"CVE-2020-21489","kev_date_added":null,"published":"2023-06-20"},{"cvss_score":9.8,"headline":"FeehiCMS has an arbitrary file upload vulnerability","id":"CVE-2020-21516","kev_date_added":null,"published":"2022-09-06"},{"cvss_score":6.9,"headline":"FeehiCMS TimThumb timthumb.php server-side request forgery","id":"CVE-2025-15264","kev_date_added":null,"published":"2025-12-30"},{"cvss_score":6.5,"headline":"FeehiCMS Has a Remote Code Execution via Unrestricted File Upload in Ad Management","id":"CVE-2025-65657","kev_date_added":null,"published":"2025-12-02"},{"cvss_score":6.5,"headline":"FeehiCMS fails to enforce server-side immutability","id":"CVE-2025-63523","kev_date_added":null,"published":"2025-12-01"}],"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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can execute arbitrary code by uploading a crafted PHP file to Feehi CMS, requiring immediate upgrade.","url":"https://insights.sbomify.com/CVE-2020-21322/"}
