Shortcomings

CVE Binary Tool (CBT)

Limited Scope: Focuses solely on binary analysis, lacking capabilities for firmware or filesystem analysis.
No Dynamic Analysis: Absence of dynamic testing means it cannot evaluate firmware behavior during execution.
No SBOM Generation: While it supports SBOM analysis, it does not inherently generate SBOMs from binaries.
Static Analysis Only: Its capabilities are confined to static analysis, potentially missing runtime vulnerabilities.
Component Coverage Limits: Might miss vulnerabilities in less common or proprietary libraries not included in its database.

EMBA

Complexity: More intricate to set up and operate, requiring a deeper understanding of firmware analysis processes.
Resource-Intensive: Firmware analysis, especially dynamic testing, demands significant system resources and time.
Specialized Focus: Tailored for firmware analysis, making it less suitable for general-purpose binary scanning tasks.
Higher Expertise Required: Effective utilization necessitates knowledge in firmware unpacking, mounting, and artifact analysis.
Manual Database Setup: Requires manual installation of CVE-Search databases, adding to setup complexity.
