Authenticated code execution via absolute path traversal
Published Oct 10, 2023 · Updated Apr 14, 2025
Absolute path traversal in Microsoft Skype for Business Server 2015 CU13 and 2019 CU7 allows remote authenticated users to execute code. Microsoft has not disclosed the affected component, attacker-controlled input, or file operation that accepts an absolute path. Exploitation requires high privileges and network access; successful execution can read or alter data and interrupt the server.
