An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2021-22941 in the wild since at least 25 Mar 2022, including in ransomware campaigns.\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-2021-22941/ (Markdown: https://insights.sbomify.com/CVE-2021-22941/index.md)","id":"CVE-2021-22941","markdown":"https://insights.sbomify.com/CVE-2021-22941/index.md","name":"CVE-2021-22941","record":{"aliases":["GHSA-83fg-h4qw-7574"],"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":"An unauthenticated attacker can remotely compromise the Citrix ShareFile storage zones controller due to improper access control.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"sharefile_storagezones_controller","vendor":"citrix"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","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-284","name":"Improper Access Control"}],"description":"Improper Access Control in Citrix ShareFile storage zones controller before 5.11.20 may allow an unauthenticated attacker to remotely compromise the storage zones controller.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2021-10-12","github_poc":2,"max_poc_stars":13,"metasploit":0,"nuclei":0,"refs":[{"date":"2021-10-12T14:52:38Z","kind":"github_poc","ref":"https://github.com/hoav18/CVE-2021-22941","stars":13,"title":null},{"date":"2025-12-02T05:58:11Z","kind":"github_poc","ref":"https://github.com/pratikjojode/citrix-cve-2021-22941-lab","stars":0,"title":"Vulnerable environment for testing CVE-2021-22941 Nuclei template"}],"tier":"exploited"},"has_fix":null,"headline":"Citrix ShareFile Improper Access Control","id":"CVE-2021-22941","indexable":true,"kev":{"dateAdded":"2022-03-25","dueDate":"2022-04-15","knownRansomwareCampaignUse":"Known","product":"ShareFile","requiredAction":"Apply updates per vendor instructions.","vendorProject":"Citrix","vulnerabilityName":"Citrix ShareFile Improper Access Control Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Open Redirect in ActionPack","id":"CVE-2021-22942"},"packages":[],"prev":{"headline":"Use after free in Node","id":"CVE-2021-22940"},"products":["Citrix ShareFile storage zones controller"],"published":"2021-09-23","related":[{"cvss_score":9.8,"headline":"Missing authorization in Citrix ShareFile Storage Zones Controller","id":"CVE-2021-22891","kev_date_added":null,"published":"2021-05-27"},{"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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["n/a"]},"summary":"An unauthenticated attacker can remotely compromise the Citrix ShareFile storage zones controller due to improper access control.","url":"https://insights.sbomify.com/CVE-2021-22941/"}
