CVE-2024-53693 has been classified to as a CRLF Injection vulnerability or weakness.

What is a Code Injection Vulnerability?

The software constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.

CVE-2024-53693 has been classified to as a Code Injection vulnerability or weakness.

What is a Resource Exhaustion Vulnerability?

The software does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources.
