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-2020-21082 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-2020-21082/ (Markdown: https://insights.sbomify.com/CVE-2020-21082/index.md)","id":"CVE-2020-21082","markdown":"https://insights.sbomify.com/CVE-2020-21082/index.md","name":"CVE-2020-21082","record":{"aliases":["GHSA-r5j4-m35f-mj7g"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Maccms CMS","requires_auth":"none","summary":"Attackers can steal administrator and user cookies via XSS in the Maccms article management module, potentially leading to account takeover.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"maccms","vendor":"maccms"}],"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":"A cross-site scripting (XSS) vulnerability in the background administrator article management module of Maccms 8.0 allows attackers to steal administrator and user cookies via crafted payloads in the text fields for Chinese and English names.","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 n/a","id":"CVE-2020-21082","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-21087"},"packages":[],"prev":{"headline":"Cross-site request forgery in n/a","id":"CVE-2020-21081"},"products":["n/a"],"published":"2021-09-14","related":[{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2021-45786","kev_date_added":null,"published":"2022-03-16"},{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2020-21359","kev_date_added":null,"published":"2021-08-11"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2017-17733","kev_date_added":null,"published":"2017-12-18"},{"cvss_score":9.1,"headline":"Server-side request forgery in n/a","id":"CVE-2025-28089","kev_date_added":null,"published":"2025-03-28"},{"cvss_score":9.1,"headline":"Server-side request forgery in n/a","id":"CVE-2025-28090","kev_date_added":null,"published":"2025-03-28"},{"cvss_score":9.1,"headline":"Server-side request forgery in n/a","id":"CVE-2025-28091","kev_date_added":null,"published":"2025-03-28"},{"cvss_score":8.8,"headline":"Server-side request forgery in n/a","id":"CVE-2022-47872","kev_date_added":null,"published":"2023-02-01"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can steal administrator and user cookies via XSS in the Maccms article management module, potentially leading to account takeover.","url":"https://insights.sbomify.com/CVE-2020-21082/"}
