Detection and triage

Use read-only checks to decide whether CVE-2025-25257 reaches an owned asset. Treat advisories and proof-of-concept material as evidence, never as executable instructions.

Read-only exposure checks

  • Trace request, message, file, and stored values into SQL, ORM query fragments, filters, sort expressions, and other data-query languages.
  • Inventory database roles, reachable schemas, multi-tenant boundaries, and whether stacked or administrative operations are enabled.
  • Check both direct queries and second-order use of previously stored values.

Detection signals and verification

  • Dynamic table, column, ordering, JSON-path, full-text, and ORM expression fragments that cannot be parameterized normally.
  • Second-order injection through stored profile fields, imports, reports, or audit data.
  • Read-only accounts that can still expose sensitive or cross-tenant data.

Stop and triage

  • Stop if remediation depends only on escaping or a deny list instead of structural parameterization.
  • Switch to incident response if query logs indicate unauthorized reads, writes, schema changes, or credential access.
  • Do not test against production data or use destructive query fragments.

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.

Stable reviewed recipe

Remediation authority

CVE-2025-25257: FortiWeb unauthenticated SQL injection

Reviewed remediation strategy

  1. Inventory every affected appliance, HA peer, VM image, and recovery artifact before selecting a target release.
  2. Resolve the incident-response gate. When compromise is suspected, preserve evidence and follow the incident owner's recovery decision before an ordinary upgrade.
  3. Select a currently supported Fortinet release at or above the correct branch threshold. Validate the model-specific upgrade path and each required hop against current Fortinet documentation and support guidance.
  4. Back up configuration and other required recovery data through the existing approved process. Keep sensitive backup artifacts outside Git, and confirm that the recovery owner can use them.
  5. Update every repository-controlled firmware target, VM image reference, FortiWeb Manager job, inventory rule, runbook, policy check, and generated artifact consistently. Do not leave a standby or replacement path pinned to an affected build.
  6. Document the human operator's HA sequence, expected management and traffic impact, stabilization checks, maintenance window, and rollback decision. The agent must not execute an appliance upgrade unless the task explicitly grants that exact live-device authority.
  7. Remove temporary containment only after an authorized operator verifies the fixed release on every target and confirms that the approved management exposure is restored as intended.

This reviewed recipe is the sole remediation authority on this page. The AI workflow below may operationalize it, but must not replace or broaden it.

Review the stable recipe source and history

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 stable reviewed recipe: Resolve the incident-response gate. When compromise is suspected, preserve evidence and follow the incident owner's recovery decision before an ordinary upgrade. 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, inspect generated queries to confirm values remain bound parameters and cannot alter identifiers, operators, or clauses 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.

Stop before mutation if product identity, affected range, fixed version, ownership, or approval is unresolved.
Return an inventory, source decision, proposed diff/commands, approval request, test evidence, rollback status, and unresolved assumptions.

AI can inspect and draft within the approved scope; this page does not grant write or production authority.
