How do I patch CVE-2025-24472?

Apply the fortinet fortios security patch or hotfix for CVE-2025-24472 on the affected version, following the vendor advisory for your exact build.

How do I detect CVE-2025-24472 across my infrastructure?

Inventory every fortinet fortios deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for exploitation at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.

How do I mitigate CVE-2025-24472 if there is no patch (or I can't update yet)?

Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.

How does O3 Security protect against CVE-2025-24472?

O3 detects and blocks CVE-2025-24472 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Is CVE-2025-24472 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-24472 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2025-24472?

CVE-2025-24472 has an EPSS (Exploit Prediction Scoring System) score of 3.1%, placing it in the 86th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

Is CVE-2025-24472 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2025-24472 (Fortinet FortiOS and FortiProxy Authentication Bypass Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2025-03-18. CISA required all US federal civilian agencies to remediate this vulnerability by 2025-04-08. The required action was: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable. This CVE has been used in known ransomware campaigns. Being listed in the KEV catalog is the strongest possible confirmation of active exploitation — treat this as a critical priority.

What type of vulnerability is CVE-2025-24472?

CVE-2025-24472 is classified as CWE-288 (CWE-288). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.
