CVE-2020-7343

Update blocking via temporary-directory manipulation

Published Jan 18, 2021 · Updated Sep 17, 2024

Missing authorization in McAfee Agent for Windows before 5.7.1 allows local users to block security product updates. McAfee identifies a temporary-file directory as the locus but does not disclose the missing authorization check or file operation. Low-privileged local access is required; successful exploitation leaves the agent running while detection content becomes outdated.
