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-2021-31839 in the wild and no public exploit code.\n\nAffected product: McAfee,LLC McAfee Agent for Windows. 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-2021-31839/ (Markdown: https://insights.sbomify.com/CVE-2021-31839/index.md)","id":"CVE-2021-31839","markdown":"https://insights.sbomify.com/CVE-2021-31839/index.md","name":"CVE-2021-31839","record":{"aliases":["GHSA-gr8f-frhq-4h8r"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"McAfee Agent for Windows","requires_auth":"low_privilege","summary":"A local user can modify or delete event logs in the McAfee Agent folder, bypassing security monitoring and altering audit trails.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"trellix","cpe":[{"product":"agent","vendor":"mcafee"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"Improper privilege management vulnerability in McAfee Agent for Windows prior to 5.7.3 allows a local user to modify event information in the MA event folder.
