Multiple vulnerabilities including an incorrect permission assignment for critical resource [CWE-732] vulnerability and a time-of-check time-of-use (TOCTOU) race condition [CWE-367] vulnerability in Fortinet FortiClientWindows before 7.0.7 allows attackers on the same file sharing network to execute commands via writing data into a windows pipe.

A relative path traversal vulnerability in Fortinet FortiClient (Windows) 7.0.0 - 7.0.7, 6.4.0 - 6.4.9, 6.2.0 - 6.2.9 and 6.0.0 - 6.0.10 allows an attacker to execute unauthorized code or commands via sending a crafted request to a specific named pipe.

A incorrect authorization in Fortinet FortiClient (Windows) 7.0.0 - 7.0.7, 6.4.0 - 6.4.9, 6.2.0 - 6.2.9 and 6.0.0 - 6.0.10 allows an attacker to execute unauthorized code or commands via sending a crafted request to a specific named pipe.

An exposure of sensitive information to an unauthorized actor vulnerabiltiy [CWE-200] in FortiClient for Mac versions 7.0.0 through 7.0.5 may allow a local authenticated attacker to obtain the SSL-VPN password in cleartext via running a logstream for the FortiTray process in the terminal.

An execution with unnecessary privileges vulnerability [CWE-250] in FortiClientWindows 7.0.0 through 7.0.3, 6.4.0 through 6.4.7, 6.2.0 through 6.2.9, 6.0.0 through 6.0.10 may allow a local attacker to perform an arbitrary file write on the system.
