Service interruption via out-of-bounds IKE request read
Published Jan 14, 2025 · Updated Jan 14, 2025
Out-of-bounds read in the IPsec IKE service of affected Fortinet appliances allows remote attackers to exhaust memory and interrupt service. The service reads beyond a buffer boundary while processing crafted IKE requests, causing memory consumption to grow until availability is lost. The IPsec IKE service must be reachable; no authentication or user interaction is required, and no confidentiality or integrity impact is reported.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=7.2.0 <=7.2.9
- Affected versionversion=7.4.0 <=7.4.4
- Affected versionversion=7.6.0
