Authenticated code execution via untrusted search path
Published Oct 10, 2023 · Updated Apr 14, 2025
Untrusted search path in affected Microsoft Skype for Business Server 2015 CU13 and 2019 CU7 builds allows remote authenticated users to execute code. Microsoft identifies an untrusted search path but does not disclose the affected executable, resource, or unsafe lookup operation. Administrative privileges are required, and successful exploitation runs attacker-controlled code on the server.
