An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-27310 exists.\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-2021-27310/ (Markdown: https://insights.sbomify.com/CVE-2021-27310/index.md)","id":"CVE-2021-27310","markdown":"https://insights.sbomify.com/CVE-2021-27310/index.md","name":"CVE-2021-27310","record":{"aliases":["GHSA-gwcx-pjgx-wqm5"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Clansphere CMS","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary scripts in victim browsers via the language parameter in Clansphere CMS.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"clansphere","vendor":"csphere"}],"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":"Clansphere CMS 2011.4 allows unauthenticated reflected XSS via \"language\" parameter.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2021/CVE-2021-27310.yaml","stars":null,"title":"Clansphere CMS 2011.4 - Cross-Site Scripting"}],"tier":"weaponised"},"has_fix":null,"headline":"Cross-site scripting in n/a","id":"CVE-2021-27310","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Gleez Cms Server Side Request Forgery (SSRF) vulnerability","id":"CVE-2021-27312"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-27309"},"products":["n/a"],"published":"2021-03-23","related":[{"cvss_score":8.7,"headline":"ClanSphere 2011.3 Local File Inclusion via cs_lang Cookie","id":"CVE-2012-10034","kev_date_added":null,"published":"2025-08-05"},{"cvss_score":7.5,"headline":"SQL injection in n/a","id":"CVE-2010-1865","kev_date_added":null,"published":"2010-05-07"},{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2022-43119","kev_date_added":null,"published":"2022-11-09"},{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2021-27309","kev_date_added":null,"published":"2021-03-23"},{"cvss_score":5,"headline":"Information disclosure in n/a","id":"CVE-2011-3714","kev_date_added":null,"published":"2011-09-23"},{"cvss_score":4.3,"headline":"Cross-site scripting in n/a","id":"CVE-2014-100010","kev_date_added":null,"published":"2015-01-13"}],"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)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"Unauthenticated attackers can execute arbitrary scripts in victim browsers via the language parameter in Clansphere CMS.","url":"https://insights.sbomify.com/CVE-2021-27310/"}
