Technical details
The vulnerability is a path traversal (CWE-22) flaw in Windows PowerShell that improperly limits pathname validation. An authorized network attacker can craft malicious path sequences to escape directory restrictions and execute arbitrary code with elevated privileges. The attack requires prior authentication and network access to the affected system. Successful exploitation leads to privilege escalation, potentially allowing the attacker to assume system-level control. Microsoft has addressed this issue with security updates.
