The product accepts input that identifies a Windows UNC share ('\\UNC\share\name') that potentially redirects access to an unintended location or arbitrary file.

Common consequences· 1

  • Confidentiality / Integrity — Read Files or Directories, Modify Files or Directories

Potential mitigations· 2

  • [Implementation]
  • [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.
