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-2021-20104 in the wild and no public exploit code.\n\nAffected product: AppNitro Machform. 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-2021-20104/ (Markdown: https://insights.sbomify.com/CVE-2021-20104/index.md)","id":"CVE-2021-20104","markdown":"https://insights.sbomify.com/CVE-2021-20104/index.md","name":"CVE-2021-20104","record":{"aliases":["GHSA-2gq4-6723-j8cq"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Machform web application","requires_auth":"none","summary":"Unauthenticated attackers can achieve remote code execution by uploading malicious files via the form attachment feature in Machform.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"machform","vendor":"machform"}],"cvss":{"score":8.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/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":"Machform prior to version 16 is vulnerable to unauthenticated remote code execution due to insufficient sanitization of file attachments uploaded with forms through upload.php.","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":"File upload in AppNitro Machform","id":"CVE-2021-20104","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Open redirect in AppNitro Machform","id":"CVE-2021-20105"},"packages":[],"prev":{"headline":"Cross-site scripting in AppNitro Machform","id":"CVE-2021-20103"},"products":["AppNitro Machform"],"published":"2021-06-29","related":[{"cvss_score":9.9,"headline":"File upload in n/a","id":"CVE-2024-37762","kev_date_added":null,"published":"2024-07-01"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2018-6410","kev_date_added":null,"published":"2018-05-26"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2018-6411","kev_date_added":null,"published":"2018-05-26"},{"cvss_score":8.8,"headline":"SQL injection in n/a","id":"CVE-2024-37765","kev_date_added":null,"published":"2024-07-01"},{"cvss_score":8.8,"headline":"Cross-site request forgery in AppNitro Machform","id":"CVE-2021-20102","kev_date_added":null,"published":"2021-06-29"},{"cvss_score":7.5,"headline":"SQL injection in n/a","id":"CVE-2013-4948","kev_date_added":null,"published":"2013-07-29"}],"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":["n/a"]},"summary":"Unauthenticated attackers can achieve remote code execution by uploading malicious files via the form attachment feature in Machform.","url":"https://insights.sbomify.com/CVE-2021-20104/"}
