Description
The issue is related to an interpretation conflict in the Fortinet IPS Engine, which can be exploited by an attacker to evade IPS features.

For Fortinet IPS Engine version 7.166, update to a fixed version to resolve the issue.
For Fortinet IPS Engine version 7.321, update to a fixed version to resolve the issue.
