CWE-178Improper Handling of Case Sensitivity

Description

The product does not properly account for differences in case sensitivity when accessing or determining the properties of a resource, leading to inconsistent results.

Common consequences

• Access Control→Bypass Protection Mechanism
  [object Object]

Potential mitigations

• Architecture and Design
  Avoid making decisions based on names of resources (e.g. files) if those resources can have alternate names.
• Implementation
  [object Object]
• Implementation
  Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174). Such errors could be used to bypass allowlist validation schemes by introducing dangerous inputs after they have been checked.
