CVE-2022-23441Network attack vector

Collector impersonation via hard-coded cryptographic key

Published Apr 6, 2022 · Updated Oct 25, 2024

Hard-coded key use in Fortinet FortiEDR 4.0.0 and 5.0.0 through 5.0.2 allows remote attackers to forge collector messages. Fortinet has not disclosed the key's storage locus or the collector-message verification operation that trusts it. Network access alone is sufficient; the disclosed consequence is collector impersonation and forged telemetry, not service interruption.
