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-2021-23872 in the wild and no public exploit code.\n\nAffected product: McAfee,LLC McAfee Total Protection (MTP). 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-2021-23872/ (Markdown: https://insights.sbomify.com/CVE-2021-23872/index.md)","id":"CVE-2021-23872","markdown":"https://insights.sbomify.com/CVE-2021-23872/index.md","name":"CVE-2021-23872","record":{"aliases":["GHSA-w9xp-gh5g-rf6p"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"McAfee Total Protection","requires_auth":"low_privilege","summary":"A local attacker can gain elevated privileges by manipulating symbolic links in the File Lock component's IOCTL interface.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"trellix","cpe":[{"product":"total_protection","vendor":"mcafee"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"Privilege Escalation vulnerability in the File Lock component of McAfee Total Protection (MTP) prior to 16.0.32 allows a local user to gain elevated privileges by manipulating a symbolic link in the IOCTL interface.","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 vulnerability in McAfee Total Protection (MTP)","id":"CVE-2021-23872","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":"McAfee Total Protection (MTP) privilege escalation vulnerability","id":"CVE-2021-23873"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-23863"},"products":["McAfee Total Protection (MTP)"],"published":"2021-05-12","related":[{"cvss_score":8.2,"headline":"McAfee Total Protection (MTP) Improper Privilege Management","id":"CVE-2021-23874","kev_date_added":"2021-11-03","published":"2021-02-10"},{"cvss_score":7.8,"headline":"Security feature bypass in n/a","id":"CVE-2023-24579","kev_date_added":null,"published":"2023-03-13"},{"cvss_score":7.8,"headline":"Path traversal in n/a","id":"CVE-2022-43751","kev_date_added":null,"published":"2022-11-22"},{"cvss_score":7.8,"headline":"Privilege Escalation vulnerability in McAfee Total Protection (MTP)","id":"CVE-2021-23891","kev_date_added":null,"published":"2021-05-12"},{"cvss_score":7.8,"headline":"McAfee Total Protection (MTP) privilege escalation vulnerability","id":"CVE-2021-23873","kev_date_added":null,"published":"2021-02-10"},{"cvss_score":7.8,"headline":"McAfee Total Protection (MTP) Bypass Remote Procedure call vulnerability","id":"CVE-2021-23876","kev_date_added":null,"published":"2021-02-10"}],"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":["McAfee,LLC"]},"summary":"A local attacker can gain elevated privileges by manipulating symbolic links in the File Lock component's IOCTL interface.","url":"https://insights.sbomify.com/CVE-2021-23872/"}
