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: There is no known exploitation of CVE-2021-23892 in the wild and no public exploit code.\n\nAffected product: McAfee,LLC McAfee Endpoint Security (ENS) for Linux. 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-2021-23892/ (Markdown: https://insights.sbomify.com/CVE-2021-23892/index.md)","id":"CVE-2021-23892","markdown":"https://insights.sbomify.com/CVE-2021-23892/index.md","name":"CVE-2021-23892","record":{"aliases":["GHSA-2pf3-gjp3-cx53"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Endpoint Security Linux","requires_auth":"low_privilege","summary":"A local attacker can exploit a race condition during installation to escalate privileges and execute arbitrary code on Linux systems.","user_interaction":"required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"trellix","cpe":[{"product":"endpoint_security_for_linux_threat_prevention","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-367","name":"Time-of-check Time-of-use (TOCTOU) Race Condition"},{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"By exploiting a time of check to time of use (TOCTOU) race condition during the Endpoint Security for Linux Threat Prevention and Firewall (ENSL TP/FW) installation process, a local user can perform a privilege escalation attack to obtain administrator privileges for the purpose of executing arbitrary code through insecure use of predictable temporary file locations.","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":"Race condition in McAfee Endpoint Security (ENS) for Linux","id":"CVE-2021-23892","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege Escalation vulnerability in McAfee Drive Encryption (MDE)","id":"CVE-2021-23893"},"packages":[],"prev":{"headline":"Privilege Escalation vulnerability in McAfee Total Protection (MTP)","id":"CVE-2021-23891"},"products":["McAfee Endpoint Security (ENS) for Linux"],"published":"2021-05-12","related":[{"cvss_score":5.6,"headline":"Endpoint Security for Linux Threat Prevention (ENSLTP) privilege escalation vulnerability","id":"CVE-2018-6693","kev_date_added":null,"published":"2018-09-18"}],"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 exploit a race condition during installation to escalate privileges and execute arbitrary code on Linux systems.","url":"https://insights.sbomify.com/CVE-2021-23892/"}
