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-2021-23876 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-2021-23876/ (Markdown: https://insights.sbomify.com/CVE-2021-23876/index.md)","id":"CVE-2021-23876","markdown":"https://insights.sbomify.com/CVE-2021-23876/index.md","name":"CVE-2021-23876","record":{"aliases":["GHSA-cvgp-h469-9f24"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"McAfee Total Protection","requires_auth":"low_privilege","summary":"A local user can bypass RPC restrictions to gain SYSTEM privileges and modify arbitrary files, potentially causing denial of service.","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-269","name":"Improper Privilege Management"}],"description":"Bypass Remote Procedure call in McAfee Total Protection (MTP) prior to 16.0.30 allows a local user to gain elevated privileges and perform arbitrary file modification as the SYSTEM user potentially causing Denial of Service via executing carefully constructed malware.","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":"McAfee Total Protection (MTP) Bypass Remote Procedure call vulnerability","id":"CVE-2021-23876","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-2021-23877"},"packages":[],"prev":{"headline":"McAfee Total Protection (MTP) Improper Privilege Management","id":"CVE-2021-23874"},"products":["McAfee Total Protection (MTP)"],"published":"2021-02-10","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-2021-23872","kev_date_added":null,"published":"2021-05-12"},{"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"}],"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 user can bypass RPC restrictions to gain SYSTEM privileges and modify arbitrary files, potentially causing denial of service.","url":"https://insights.sbomify.com/CVE-2021-23876/"}
