It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: Yes. Attackers have exploited CVE-2021-23874 in the wild since at least 3 Nov 2021.\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-2021-23874/ (Markdown: https://insights.sbomify.com/CVE-2021-23874/index.md)","id":"CVE-2021-23874","markdown":"https://insights.sbomify.com/CVE-2021-23874/index.md","name":"CVE-2021-23874","record":{"aliases":["GHSA-jx9f-q7vh-wf4p"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"McAfee Total Protection","requires_auth":"low_privilege","summary":"A local attacker can bypass self-defense mechanisms to gain elevated privileges and execute arbitrary code on systems running McAfee Total Protection.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"trellix","cpe":[{"product":"total_protection","vendor":"mcafee"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-732","name":"Incorrect Permission Assignment for Critical Resource"},{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"Arbitrary Process Execution vulnerability in McAfee Total Protection (MTP) prior to 16.0.30 allows a local user to gain elevated privileges and execute arbitrary code bypassing MTP self-defense.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"exploited"},"has_fix":null,"headline":"McAfee Total Protection (MTP) Improper Privilege Management","id":"CVE-2021-23874","indexable":true,"kev":{"dateAdded":"2021-11-03","dueDate":"2021-11-17","knownRansomwareCampaignUse":"Unknown","product":"McAfee Total Protection (MTP)","requiredAction":"Apply updates per vendor instructions.","vendorProject":"McAfee","vulnerabilityName":"McAfee Total Protection (MTP) Improper Privilege Management Vulnerability"},"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) Bypass Remote Procedure call vulnerability","id":"CVE-2021-23876"},"packages":[],"prev":{"headline":"McAfee Total Protection (MTP) privilege escalation vulnerability","id":"CVE-2021-23873"},"products":["McAfee Total Protection (MTP)"],"published":"2021-02-10","related":[{"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"},{"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":"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)"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["McAfee,LLC"]},"summary":"A local attacker can bypass self-defense mechanisms to gain elevated privileges and execute arbitrary code on systems running McAfee Total Protection.","url":"https://insights.sbomify.com/CVE-2021-23874/"}
