Summary

FortiClient for Linux versions 6.2.1 and earlier exhibit a vulnerability that allows users with low privileges to execute arbitrary file overwrites as root. This occurs via specially crafted 'BackupConfig' IPC client requests directed at the fctsched process, enabling unauthorized modifications to system files. Moreover, versions 6.2.2 and earlier permit low privilege users to write to system backup files through the GUI, resulting in potential root access and system instability. These weaknesses highlight significant risks in maintaining system integrity and protecting sensitive data.
