Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-27231 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-2021-27231/ (Markdown: https://insights.sbomify.com/CVE-2021-27231/index.md)","id":"CVE-2021-27231","markdown":"https://insights.sbomify.com/CVE-2021-27231/index.md","name":"CVE-2021-27231","record":{"aliases":["GHSA-g29r-mmqp-whm4"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Hestia Control Panel","requires_auth":"low_privilege","summary":"Authenticated users can create subdomains for other customers' domains, enabling service or email spoofing in shared hosting environments.","user_interaction":"not_required","vuln_class":"business_logic"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"control_panel","vendor":"hestiacp"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[],"description":"Hestia Control Panel 1.3.5 and below, in a shared-hosting environment, sometimes allows remote authenticated users to create a subdomain for a different customer's domain name, leading to spoofing of services or email messages.","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":"Business logic in n/a","id":"CVE-2021-27231","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"business_logic","year":"2021"},"n_packages":0,"n_references":4,"next":{"headline":"Memory corruption in n/a","id":"CVE-2021-27232"},"packages":[],"prev":{"headline":"Code injection in n/a","id":"CVE-2021-27230"},"products":["n/a"],"published":"2021-02-16","related":[{"cvss_score":9.9,"headline":"OS Command Injection in hestiacp/hestiacp","id":"CVE-2022-2550","kev_date_added":null,"published":"2022-07-27"},{"cvss_score":9.9,"headline":"Command Injection Vulnerability in hestiacp/hestiacp","id":"CVE-2022-1509","kev_date_added":null,"published":"2022-04-28"},{"cvss_score":9.1,"headline":"Incorrect Privilege Assignment in hestiacp/hestiacp","id":"CVE-2022-2626","kev_date_added":null,"published":"2022-08-05"},{"cvss_score":8.8,"headline":"Privilege Chaining in hestiacp/hestiacp","id":"CVE-2023-5839","kev_date_added":null,"published":"2023-10-29"},{"cvss_score":8.7,"headline":"HestiaCP \u003c 1.9.5 Authenticated OS Command Injection via DNS Record Management","id":"CVE-2025-30007","kev_date_added":null,"published":"2026-07-10"},{"cvss_score":8.5,"headline":"Code Injection in hestiacp/hestiacp","id":"CVE-2022-2636","kev_date_added":null,"published":"2022-08-05"},{"cvss_score":6.6,"headline":"Cross-site Scripting (XSS) - Reflected in hestiacp/hestiacp","id":"CVE-2022-0838","kev_date_added":null,"published":"2022-03-04"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"Authenticated users can create subdomains for other customers' domains, enabling service or email spoofing in shared hosting environments.","url":"https://insights.sbomify.com/CVE-2021-27231/"}
