CVE-2025-58325: 
FortiOS vulnerability analysis and mitigation

An Incorrect Provision of Specified Functionality vulnerability (CVE-2025-58325) was discovered in FortiOS operating system on October 14, 2025. The vulnerability affects multiple versions of FortiOS including 7.6.0, 7.4.0 through 7.4.5, 7.2.5 through 7.2.10, 7.0.0 through 7.0.15, and all versions of 6.4. This security flaw could allow local authenticated attackers to execute system commands through crafted CLI commands (Fortinet Advisory, NVD).

The vulnerability is classified as CWE-684 (Incorrect Provision of Specified Functionality) and received a CVSS v3.1 base score of 7.8 (High severity). The attack requires local access and high-level privileges, with no user interaction needed. The vulnerability specifically affects the CLI component of FortiOS, enabling authenticated users to bypass command line interface restrictions. The attack complexity is rated as low, making it relatively straightforward for attackers who have already gained administrative access (GBHackers).

If successfully exploited, this vulnerability allows attackers with administrative privileges to execute unauthorized system commands, potentially leading to privilege escalation and full system compromise. The vulnerability affects a wide range of Fortinet firewall models including the 100E/101E, 100F/101F, 1100E/1101E, 1800F/1801F, 2200E/2201E, and several other high-end models up to the 7000F series (Fortinet Advisory).

Fortinet has released patches to address this vulnerability. Organizations are advised to upgrade to the following fixed versions: FortiOS 7.6.1 or above for 7.6 branch, 7.4.6 or above for 7.4 branch, 7.2.11 or above for 7.2 branch, and 7.0.16 or above for 7.0 branch. Users of FortiOS 6.4 should migrate to a fixed release as no patch is available for this end-of-life version. Fortinet recommends using their upgrade path tool for proper migration planning (Fortinet Advisory).

The vulnerability was internally discovered and reported by Francois Ropert of the Fortinet PSIRT team. The security community has classified this as a high-severity issue due to its potential impact on enterprise networks relying on Fortinet's firewalls and security appliances (Security Week).
