CVE-2023-29586 — Code Sector TeraCopy 3.9.7 does not perform proper access validation on the source folder during a copy operation

Medium CVSS 5.5

Code Sector TeraCopy 3.9.7 does not perform proper access validation on the source folder during a copy operation. This leads to Arbitrary File Read by allowing any user to copy any directory in the system to a directory they control. NOTE: the Supplier disputes this because only admin users can copy arbitrary folders, and because the 143984 reference is about a different concern (unrelated to directory copying) that was fixed in 3.5b.

Matched remediation archetype

Authorization bypass, IDOR, and cross-tenant access

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
