Published Feb 8, 2024 · Updated Jun 17, 2025

Path traversal in Atos Unify OpenScape Voice Trace Manager V8 before V8 R0.9.11 allows remote authenticated users to read files. The vendor identifies the user interface as the affected component but does not disclose the request parameter or path-validation operation that accepts traversal sequences. Exploitation requires an authenticated user-interface session and exposes files without reported modification or service interruption.
