It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-22928 in the wild and no public exploit code.\n\nAffected product: Citrix Virtual Apps and Desktops. 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-2021-22928/ (Markdown: https://insights.sbomify.com/CVE-2021-22928/index.md)","id":"CVE-2021-22928","markdown":"https://insights.sbomify.com/CVE-2021-22928/index.md","name":"CVE-2021-22928","record":{"aliases":["GHSA-469p-6wj5-vcqr"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Citrix Virtual Apps","requires_auth":"low_privilege","summary":"Privilege escalation in Citrix Virtual Apps allows users to gain SYSTEM privileges on Windows VDAs with specific profile management plugins installed.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"virtual_apps_and_desktops","vendor":"citrix"},{"product":"xenapp","vendor":"citrix"},{"product":"xendesktop","vendor":"citrix"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"A vulnerability has been identified in Citrix Virtual Apps and Desktops that could, if exploited, allow a user of a Windows VDA that has either Citrix Profile Management or Citrix Profile Management WMI Plugin installed to escalate their privilege level on that Windows VDA to SYSTEM.","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":"Privilege escalation in Citrix Virtual Apps and Desktops","id":"CVE-2021-22928","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in https://github.com/brave/brave-core","id":"CVE-2021-22929"},"packages":[],"prev":{"headline":"Other in Citrix ADC, Citrix Gateway","id":"CVE-2021-22927"},"products":["Citrix Virtual Apps and Desktops"],"published":"2021-08-05","related":[{"cvss_score":8.8,"headline":"Privilege escalation in Citrix Virtual Apps and Desktops","id":"CVE-2020-8283","kev_date_added":null,"published":"2020-12-14"},{"cvss_score":8.8,"headline":"Privilege escalation in Citrix Virtual Apps and Desktops","id":"CVE-2020-8269","kev_date_added":null,"published":"2020-11-16"},{"cvss_score":8.8,"headline":"Command injection in Citrix Virtual Apps and Desktops","id":"CVE-2020-8270","kev_date_added":null,"published":"2020-11-16"},{"cvss_score":8.5,"headline":"Local Privilege escalation allows a low-privileged user to gain SYSTEM privileges","id":"CVE-2024-6151","kev_date_added":null,"published":"2024-07-10"},{"cvss_score":7.8,"headline":"Privilege Escalation to NT AUTHORITY\\SYSTEM on the vulnerable VDA","id":"CVE-2023-24483","kev_date_added":null,"published":"2023-02-16"},{"cvss_score":7.3,"headline":"Local Privilege escalation allows a low-privileged user to gain SYSTEM privileges","id":"CVE-2025-6759","kev_date_added":null,"published":"2025-07-08"}],"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":"Privilege escalation in Citrix Virtual Apps allows users to gain SYSTEM privileges on Windows VDAs with specific profile management plugins installed.","url":"https://insights.sbomify.com/CVE-2021-22928/"}
