The vendors haven’t shared many details about the security flaws, yet they have briefly described the issues alongside the detailed list of affected products.

Specifically, Fortinet mentioned detecting multiple command injection vulnerabilities in the FortiADC web interface.

According to its advisory, the bug existed due to the improper neutralization of special elements used in an OS command. Exploiting the flaw could allow an unauthenticated adversary accessing the web interface to execute commands via specially crafted HTTP requests.

Similarly, the vendors have shared another advisory highlighting the vulnerabilities in the FortiTester device. As described, they detected numerous command injection vulnerabilities in the GUI and API due to improper neutralization of special elements in OS commands. Exploiting the flaw could let an unauthenticated attacker execute arbitrary commands in the shell.
