How severe is CVE-2025-25257?

CVE-2025-25257 has a CVSS score of 9.8/10, rated CRITICAL. Immediate patching is strongly recommended.

Which products are affected by CVE-2025-25257?

Affected package information for CVE-2025-25257 is not yet fully mapped. Check the official advisory links for details.

How do I patch CVE-2025-25257?

No patch has shipped for CVE-2025-25257 yet — track the fortinet fortiweb advisory for a fixed release and apply the workarounds below in the meantime.

How do I detect CVE-2025-25257 across my infrastructure?

Inventory every fortinet fortiweb 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-2025-25257 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-2025-25257?

O3 detects and blocks CVE-2025-25257 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-2025-25257 actively exploited in the wild?

Yes. There are 4 known exploit references for CVE-2025-25257, including 1 documented proof-of-concept exploit on Exploit-DB. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2025-25257?

CVE-2025-25257 has an EPSS (Exploit Prediction Scoring System) score of 96.7%, placing it in the 100th 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. A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.

Is CVE-2025-25257 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2025-25257 (Fortinet FortiWeb SQL Injection Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2025-07-18. CISA required all US federal civilian agencies to remediate this vulnerability by 2025-08-08. 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. 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-2025-25257?

CVE-2025-25257 is classified as SQL Injection (CWE-89). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

Which products and versions are affected by CVE-2025-25257?

CVE-2025-25257 affects fortinet fortiweb (34 versions, e.g. 7.0.0, 7.0.1, 7.0.2…). Check the affected-products list on this page against your deployed version to confirm exposure.

Is there exploit tooling available for CVE-2025-25257?

A Nuclei detection template exists for CVE-2025-25257, meaning automated scanners can fingerprint it. Public exploit tooling significantly increases real-world risk — prioritize patching and ensure detection coverage. Exploit tooling should only ever be used in isolated, authorized testing environments.

When was CVE-2025-25257 published, and has it been updated?

CVE-2025-25257 was published on July 17, 2025 and was last updated on February 26, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
