An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-27237 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-2021-27237/ (Markdown: https://insights.sbomify.com/CVE-2021-27237/index.md)","id":"CVE-2021-27237","markdown":"https://insights.sbomify.com/CVE-2021-27237/index.md","name":"CVE-2021-27237","record":{"aliases":["GHSA-wmxf-4m6r-mvjr"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"BlackCat CMS","requires_auth":"high_privilege","summary":"An admin can inject malicious scripts via the Display Name field in BlackCat CMS, potentially leading to code execution or account takeover.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"blackcat_cms","vendor":"blackcat-cms"}],"cvss":{"score":4.8,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:H/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":"The admin panel in BlackCat CMS 1.3.6 allows stored XSS (by an admin) via the Display Name field to backend/preferences/ajax_save.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-2021-27237","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"Memory corruption in Multiple Routers","id":"CVE-2021-27239"},"packages":[],"prev":{"headline":"Path traversal in n/a","id":"CVE-2021-27236"},"products":["n/a"],"published":"2021-02-16","related":[{"cvss_score":8.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2020-25453","kev_date_added":null,"published":"2020-09-15"},{"cvss_score":8.8,"headline":"File upload in n/a","id":"CVE-2017-14399","kev_date_added":null,"published":"2017-09-12"},{"cvss_score":8.8,"headline":"Code injection in n/a","id":"CVE-2017-14048","kev_date_added":null,"published":"2017-08-31"},{"cvss_score":8.8,"headline":"File upload in n/a","id":"CVE-2017-14050","kev_date_added":null,"published":"2017-08-31"},{"cvss_score":8.6,"headline":"Blackcat CMS 1.4 Remote Code Execution via Jquery Plugin Manager","id":"CVE-2023-53892","kev_date_added":null,"published":"2025-12-15"},{"cvss_score":7.5,"headline":"Path traversal in n/a","id":"CVE-2015-5079","kev_date_added":null,"published":"2018-02-28"},{"cvss_score":6.5,"headline":"File upload in n/a","id":"CVE-2017-13670","kev_date_added":null,"published":"2017-08-31"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"An admin can inject malicious scripts via the Display Name field in BlackCat CMS, potentially leading to code execution or account takeover.","url":"https://insights.sbomify.com/CVE-2021-27237/"}
