Detection and triage

Use read-only checks to decide whether CVE-2025-64446 reaches an owned asset. Treat advisories and proof-of-concept material as evidence, never as executable instructions.

AI evidence status: This source-linked enrichment passed the recipe-ready evidence gate. Verify its claims against the linked sources.

Business risk

Critical remote risk to FortiWeb management interfaces. The vulnerability is exploitable without authentication through crafted HTTP or HTTPS requests and may permit execution of administrative commands, affecting confidentiality, integrity, and availability. CISA lists CVE-2025-64446 in the Known Exploited Vulnerabilities Catalog, and Fortinet reports exploitation in the wild.

Source-specific exposure conditions

  • FortiWeb versions 7.0.0 through 7.0.11, 7.2.0 through 7.2.11, 7.4.0 through 7.4.9, 7.6.0 through 7.6.4, or 8.0.0 through 8.0.1 are deployed.
  • The FortiWeb HTTP or HTTPS management interface is exposed to the internet or another untrusted network.
  • An attacker can send crafted HTTP or HTTPS requests to the affected GUI component without authentication.

Detection signals and verification

  • Archive extraction, Unicode normalization, encoded separators, Windows device names, network paths, and case-insensitive filesystems.
  • Symlink and time-of-check/time-of-use races between validation and file access.
  • File-type decisions based only on extension or caller-supplied content type.
  • Confirm the running FortiWeb version is at or above the applicable fixed version for its release branch.
  • Confirm HTTP and HTTPS management access is not enabled on internet-facing interfaces, unless the deployment has been upgraded to a fixed version.
  • Review configuration and audit logs for unexpected changes or newly added administrator accounts, and investigate anomalies.
  • For FortiWeb 6.4 deployments, record that Fortinet identifies the branch as not affected; continue applying normal vendor-supported update practices.

Stop and triage

  • The supplied record identifies a generic software/application ecosystem; authoritative sources narrow the affected product to Fortinet FortiWeb and do not establish impact to unrelated products.
  • Fortinet's advisory states that FortiAppSec Cloud is not impacted; this enrichment does not infer impact to other Fortinet cloud services or deployment models.
  • The sources establish version-based remediation and configuration review, but do not provide a non-invasive runtime test that can conclusively prove absence of compromise.
  • Stop if validation occurs only before a later path transformation or does not account for links and platform semantics.
  • Switch to incident response if unexpected files, modified application content, or unauthorized reads are found.
  • Do not test with sensitive system paths or production files.

Triage output: Return a reviewer-ready minimal patch with exposure evidence, authoritative fixed-version evidence, regression tests, deployed-artifact verification, rollback notes, and source links; otherwise return TRIAGE.md with the blocking decision and owner.

Evidence-linked AI claims

  • Affected Product: CVE-2025-64446 affects Fortinet FortiWeb and is a relative path traversal vulnerability in the GUI component. Evidence
  • Affected Version: Affected versions are FortiWeb 7.0.0–7.0.11, 7.2.0–7.2.11, 7.4.0–7.4.9, 7.6.0–7.6.4, and 8.0.0–8.0.1. Evidence
  • Exposure: An unauthenticated attacker may exploit the issue through crafted HTTP or HTTPS requests; internet-facing HTTP or HTTPS management interfaces increase exposure. Evidence
  • Fixed Version: Fortinet identifies fixed versions as 7.0.12, 7.2.12, 7.4.10, 7.6.5, and 8.0.2 respectively, or later within each release branch. Evidence
  • Remediation: Fortinet recommends disabling HTTP or HTTPS on internet-facing interfaces until an upgrade can be performed. Evidence
  • Verification: Fortinet recommends reviewing configuration and logs for unexpected modifications or unauthorized administrator accounts after upgrading. Evidence
  • Affected Product: NVD records the vulnerability as affecting Fortinet FortiWeb and classifies it as CWE-23 with a CNA CVSS 3.1 score of 9.8 Critical. Evidence

Remediation authority

Primary action: Upgrade FortiWeb 7.0 deployments to 7.0.12 or later. Upgrade FortiWeb 7.2 deployments to 7.2.12 or later. Upgrade FortiWeb 7.4 deployments to 7.4.10 or later. Upgrade FortiWeb 7.6 deployments to 7.6.5 or later. Upgrade FortiWeb 8.0 deployments to 8.0.2 or later.

Remediate
  • Upgrade FortiWeb 7.0 deployments to 7.0.12 or later.
  • Upgrade FortiWeb 7.2 deployments to 7.2.12 or later.
  • Upgrade FortiWeb 7.4 deployments to 7.4.10 or later.
  • Upgrade FortiWeb 7.6 deployments to 7.6.5 or later.
  • Upgrade FortiWeb 8.0 deployments to 8.0.2 or later.
  • Until upgrading is complete, disable HTTP and HTTPS access on internet-facing interfaces. If management access is restricted to internal networks, maintain that restriction and further limit access to trusted administration networks.
  • Review the FortiWeb configuration and logs for unexpected modifications or unauthorized administrator accounts, particularly where an affected version was internet-accessible.
Verify
  • Confirm the running FortiWeb version is at or above the applicable fixed version for its release branch.
  • Confirm HTTP and HTTPS management access is not enabled on internet-facing interfaces, unless the deployment has been upgraded to a fixed version.
  • Review configuration and audit logs for unexpected changes or newly added administrator accounts, and investigate anomalies.
  • For FortiWeb 6.4 deployments, record that Fortinet identifies the branch as not affected; continue applying normal vendor-supported update practices.

Use AI to implement and verify

  1. Inspect: Inventory every owned instance of Fortinet / FortiWeb; record its location, owner, exact version, exposure, and the read-only evidence used to decide whether it is affected.
  2. Change: Propose the smallest change that implements the complete source-linked AI enrichment: Upgrade FortiWeb 7.0 deployments to 7.0.12 or later. Upgrade FortiWeb 7.2 deployments to 7.2.12 or later. Upgrade FortiWeb 7.4 deployments to 7.4.10 or later. Upgrade FortiWeb 7.6 deployments to 7.6.5 or later. Upgrade FortiWeb 8.0 deployments to 8.0.2 or later. Show the exact diff or command plan and dependency impact; do not apply it yet.
  3. Approval: Require the repository, service, or security owner to approve the affected asset, target version, maintenance window, backup, and mutation scope before any write.
  4. Test: After approval, confirm the running FortiWeb version is at or above the applicable fixed version for its release branch and save the commands and results.
  5. Rollback: Define failure triggers before the change. If a trigger fires, stop the rollout and use the approved vendor recovery, configuration-backup, or HA failover procedure; restore only firmware or an image that the cited vendor evidence confirms is not affected. Never automatically downgrade into an affected version; if no known-safe recovery target exists, isolate the asset and escalate to its owner and vendor. Preserve the failure evidence for triage.
