What is CVE-2022-43946?

Fortinet FortiClient Windows versions prior to 7.0.7 contain multiple vulnerabilities that can lead to significant security risks. An improper permission assignment allows attackers on the same file-sharing network to gain unauthorized access to critical resources. Additionally, a time-of-check to time-of-use (TOCTOU) race condition vulnerability enables attackers to manipulate command execution by writing data into a Windows pipe, potentially leading to further exploitation. Mitigating these vulnerabilities is essential for ensuring comprehensive network security.
