An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-20103 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-2021-20103/ (Markdown: https://insights.sbomify.com/CVE-2021-20103/index.md)","id":"CVE-2021-20103","markdown":"https://insights.sbomify.com/CVE-2021-20103/index.md","name":"CVE-2021-20103","record":{"aliases":["GHSA-89p7-qxqf-9q7p"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Machform web application","requires_auth":"none","summary":"Stored XSS in Machform allows attackers to inject malicious scripts via file attachments, potentially leading to session hijacking or code execution.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"machform","vendor":"machform"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Machform prior to version 16 is vulnerable to stored cross-site scripting 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":"Cross-site scripting in AppNitro Machform","id":"CVE-2021-20103","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"File upload in AppNitro Machform","id":"CVE-2021-20104"},"packages":[],"prev":{"headline":"Cross-site request forgery in AppNitro Machform","id":"CVE-2021-20102"},"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":8.1,"headline":"File upload in AppNitro Machform","id":"CVE-2021-20104","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":"Stored XSS in Machform allows attackers to inject malicious scripts via file attachments, potentially leading to session hijacking or code execution.","url":"https://insights.sbomify.com/CVE-2021-20103/"}
