Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly enforces validation of unverified input parameters in the widget framework module to prevent DoS exploitation.
Restricts types and quantities of inputs to the widget framework, mitigating DoS from malformed or excessive parameters.
Limits the effects of DoS attacks resulting from adjacent network exploitation of unvalidated inputs affecting availability.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Improper input validation (CWE-20) in widget framework directly enables application/system exploitation resulting in DoS (availability impact only).
NVD Description
Vulnerability of input parameters not being verified in the widget framework module Impact: Successful exploitation of this vulnerability may affect availability.
Deeper analysisAI
CVE-2024-56437 is a vulnerability involving input parameters not being verified in the widget framework module, classified under CWE-20 (Improper Input Validation) with NVD-CWE-noinfo. This flaw affects availability upon successful exploitation and carries a CVSS v3.1 base score of 5.7 (AV:A/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H). The CVE was published on 2025-01-08T03:15:08.840.
