A improper verification of source of a communication channel in Fortinet FortiOS with IPS engine version 7.201 through 7.214, 7.001 through 7.113, 6.001 through 6.121, 5.001 through 5.258 and before 4.086 allows a remote and unauthenticated attacker to trigger the sending of "blocked page" HTML data to an arbitrary victim via crafted TCP requests, potentially flooding the victim.

The version of Fortigate installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the FG-IR-22-073 advisory.
