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-2020-21487 in the wild and no public exploit code.\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-2020-21487/ (Markdown: https://insights.sbomify.com/CVE-2020-21487/index.md)","id":"CVE-2020-21487","markdown":"https://insights.sbomify.com/CVE-2020-21487/index.md","name":"CVE-2020-21487","record":{"aliases":["GHSA-rff5-9cw2-46c6"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"pfSense ACME package","requires_auth":"none","summary":"Attackers can execute arbitrary code via Cross-Site Scripting in the ACME package's certificate configuration field, compromising pfSense network devices.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"pfsense","vendor":"netgate"},{"product":"pfsense_acme_package","vendor":"netgate"}],"cvss":{"score":9.6,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Cross Site Scripting vulnerability found in Netgate pfSense 2.4.4 and ACME package v.0.6.3 allows attackers to execute arbitrary code via the RootFolder field of acme_certificates.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":false,"headline":"Cross-site scripting in n/a","id":"CVE-2020-21487","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Liufee CMS File Upload vulnerability","id":"CVE-2020-21489"},"packages":[],"prev":{"headline":"SQL injection in n/a","id":"CVE-2020-21486"},"products":["n/a"],"published":"2023-04-04","related":[{"cvss_score":9.8,"headline":"Path traversal in n/a","id":"CVE-2019-16915","kev_date_added":null,"published":"2019-09-26"},{"cvss_score":9.3,"headline":"Cross-site scripting in n/a","id":"CVE-2024-46538","kev_date_added":null,"published":"2024-10-22"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2023-48123","kev_date_added":null,"published":"2023-12-06"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2023-42326","kev_date_added":null,"published":"2023-11-14"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2023-27253","kev_date_added":null,"published":"2023-03-17"},{"cvss_score":8.8,"headline":"Command injection in pfSense CE and pfSense Plus","id":"CVE-2022-24299","kev_date_added":null,"published":"2022-03-31"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-02-13","vendors":["n/a"]},"summary":"Attackers can execute arbitrary code via Cross-Site Scripting in the ACME package's certificate configuration field, compromising pfSense network devices.","url":"https://insights.sbomify.com/CVE-2020-21487/"}
