An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-22891 and fix it if it is affected.\n\nWhat it is: CVE-2021-22891 is a critical missing authorization vulnerability in Citrix ShareFile Storage Zones Controller, published on 27 May 2021. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-22891 in the wild and no public exploit code.\n\nAffected product: Citrix ShareFile Storage Zones Controller. 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-2021-22891/ (Markdown: https://insights.sbomify.com/CVE-2021-22891/index.md)","id":"CVE-2021-22891","markdown":"https://insights.sbomify.com/CVE-2021-22891/index.md","name":"CVE-2021-22891","record":{"aliases":["GHSA-8jfh-ph5c-r74h"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Citrix ShareFile Storage Zones","requires_auth":"none","summary":"Unauthenticated attackers can remotely compromise the Citrix ShareFile Storage Zones Controller due to missing authorization checks.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"sharefile_storagezones_controller","vendor":"citrix"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"A missing authorization vulnerability exists in Citrix ShareFile Storage Zones Controller before 5.7.3, 5.8.3, 5.9.3, 5.10.1 and 5.11.18 may allow unauthenticated remote compromise of the Storage Zones Controller.","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":"Missing authorization in Citrix ShareFile Storage Zones Controller","id":"CVE-2021-22891","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in Rocket.Chat server","id":"CVE-2021-22892"},"packages":[],"prev":{"headline":"Security feature bypass in https://github.com/curl/curl","id":"CVE-2021-22890"},"products":["Citrix ShareFile Storage Zones Controller"],"published":"2021-05-27","related":[{"cvss_score":9.8,"headline":"Citrix ShareFile Improper Access Control","id":"CVE-2021-22941","kev_date_added":"2022-03-25","published":"2021-09-23"},{"cvss_score":7.5,"headline":"Weak cryptography in Citrix ShareFile Storage Zones Controller","id":"CVE-2021-22932","kev_date_added":null,"published":"2021-08-16"},{"cvss_score":7.5,"headline":"Path traversal in n/a","id":"CVE-2020-7473","kev_date_added":null,"published":"2020-05-07"},{"cvss_score":7.5,"headline":"Path traversal in n/a","id":"CVE-2020-8982","kev_date_added":null,"published":"2020-05-07"},{"cvss_score":7.5,"headline":"Path traversal in n/a","id":"CVE-2020-8983","kev_date_added":null,"published":"2020-05-07"},{"cvss_score":4.3,"headline":"Information disclosure in n/a","id":"CVE-2018-16969","kev_date_added":null,"published":"2018-09-26"}],"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":"Unauthenticated attackers can remotely compromise the Citrix ShareFile Storage Zones Controller due to missing authorization checks.","url":"https://insights.sbomify.com/CVE-2021-22891/"}
