Zero Day Initiative Advisories
Executive ViewAI
FortiClient versions up to 7.4.4 contain a critical file access vulnerability that could allow attackers to bypass security controls and access sensitive files on affected endpoints. This impacts all organizations using vulnerable FortiClient versions, potentially compromising data confidentiality and enabling lateral movement within the network.
Until patched: Restrict FortiClient functionality through group policies where feasible; monitor file access patterns for anomalous behavior; implement application whitelisting; enforce network segmentation to limit lateral movement if endpoints are compromised; disable unnecessary FortiClient features; enforce multi-factor authentication; increase endpoint detection and response (EDR) monitoring; require users to disable local administrator privileges.
