CVE-2023-2818

Local monitoring disruption via insecure filesystem permissions

Published Jun 27, 2023 · Updated Nov 7, 2024

Improper permission handling in Proofpoint Insider Threat Management before 7.14.3 allows local users to disrupt monitoring via filesystem access. The advisory does not identify the agent file or operation that leaves permissions insecure, so the precise filesystem locus is undisclosed. Any unprivileged Windows account with local access can trigger the condition without user interaction, interrupting agent event reporting while confidentiality and integrity remain unaffected.
