CVE-2024-24997Network attack vector

Authenticated SYSTEM command execution via path traversal

Published Apr 19, 2024 · Updated Dec 16, 2025

Path traversal in Ivanti Avalanche before 6.4.3 allows remote authenticated users to execute arbitrary commands as SYSTEM. WLAvalancheService, listening on TCP port 1777 by default, uses a user-supplied path in file operations without proper validation. Valid service credentials and network access to that port are required, and successful exploitation grants SYSTEM-level code execution.
