CVE-2024-23113 is a Fortinet multiple-products format string vulnerability that CISA added to its Known Exploited Vulnerabilities catalog on 2024-10-09. That KEV listing means defenders should treat it as a high-priority issue. The supplied corpus does not include Fortinet’s full advisory text or affected version list, so remediation should follow the vendor guidance referenced by CISA and be applied across any exposed Fortinet deployments as soon as possible.

Who should care

Organizations that operate Fortinet products, especially security and infrastructure teams responsible for exposed perimeter devices, appliances, or management interfaces. Asset owners should also care if they rely on any Fortinet product covered by the vendor advisory referenced in CISA’s KEV entry.

Technical summary

The available source data identifies the issue only as a format string vulnerability affecting Fortinet multiple products. CISA’s KEV record marks it as known exploited and points defenders to the Fortinet PSIRT advisory and NVD entry for product-specific remediation details. Because the supplied corpus does not include affected versions, exploit conditions, or patch specifics, the safest defensive stance is to inventory Fortinet deployments, consult the linked vendor guidance, and remediate or remove unsupported/unmitigable systems.

Defensive priority

High. CISA has added this CVE to the Known Exploited Vulnerabilities catalog, which signals active exploitation risk and a short remediation window (due date 2024-10-30).

Recommended defensive actions

  • Inventory all Fortinet products in your environment and determine whether they are covered by the vendor advisory referenced in the KEV record.
  • Review the linked Fortinet PSIRT guidance and apply the vendor-recommended mitigations or updates immediately.
  • If mitigations are unavailable for a deployed product, discontinue use of that product as CISA directs in the KEV guidance.
  • Prioritize internet-facing and management-plane Fortinet systems first.
  • Verify remediation by rechecking versions, configurations, and exposure after changes are applied.
