Impact Analysis

Exploitation Probability (EPSS): 96.7% chance of exploitation in the next 30 days (100th percentile). This places the vulnerability in the highest risk tier, immediate action is critical.

Exploit Availability

Public exploit code or proof-of-concept is available for CVE-2025-25257. This significantly increases the risk of exploitation, as attackers can use or adapt existing exploit code rather than developing their own. A public exploit reference has been identified. Organizations should treat this as an urgent patching priority.

Is CVE-2025-25257 being exploited?

Yes. CVE-2025-25257 is listed in CISA's Known Exploited Vulnerabilities (KEV) catalog, restricted to CVEs with confirmed active exploitation in the wild. CISA added this vulnerability on 2025-07-18. Inclusion in KEV triggers the patching mandate under BOD 22-01 for U.S. federal civilian agencies, with a remediation deadline of 2025-08-08. Additionally, public exploit code is available, which lowers the barrier for attackers.

How to fix CVE-2025-25257

Upgrade FortiOS or the affected product firmware to the fixed version listed in the FortiGuard PSIRT advisory. For FortiGate devices, use the firmware upgrade path tool to determine the correct upgrade sequence. If immediate patching is not possible, apply the recommended workaround (e.g. disabling affected features, restricting management interface access). Check the Fortinet PSIRT Advisories page for the specific patch or update. CISA's Known Exploited Vulnerabilities catalog requires U.S. federal agencies to remediate this vulnerability by the due date shown below under Binding Operational Directive 22-01. Private organizations should treat KEV entries as priority-one patches because active exploitation has been confirmed in the wild.
