How the mentioned CVE works:
CVE-2025-53679 is an OS command injection vulnerability in Fortinet FortiSandbox’s graphical user interface (GUI). It stems from improper neutralization of special elements in user inputs, classified under CWE-78. The flaw exists in versions 5.0.0 through 5.0.2 and all versions before 4.4.7. A remote attacker with privileged access can craft malicious HTTP or HTTPS requests containing OS commands. These requests target the FortiSandbox GUI, which fails to sanitize inputs before passing them to the underlying operating system shell. Consequently, injected commands are executed with the application’s privileges, allowing arbitrary code execution. This vulnerability enables attackers to compromise the system remotely, potentially leading to full control, data theft, or service disruption. Exploitation requires authenticated privileged access, but once achieved, it bypasses security mechanisms. The attack vector involves network-accessible interfaces, making it critical for exposed deployments. FortiSandbox instances handling sensitive traffic are at high risk. The vulnerability highlights input validation gaps in web management consoles. Patches are expected to enforce strict input filtering and command sanitization.
