1) Improper handling of syntactically invalid structure (CVE-ID: CVE-2024-21612)

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper handling of syntactically invalid structure error in Object Flooding Protocol (OFP) service. A remote non-authenticated attacker can cause a Denial of Service (DoS).
