CVE-2024-24999Network attack vector

SYSTEM code execution via unvalidated file paths

Published Apr 19, 2024 · Updated Dec 16, 2025

Path traversal in Ivanti Avalanche WLAvalancheService before 6.4.3 allows remote authenticated users to execute code as SYSTEM. The service listens on TCP port 1777 by default and uses a user-supplied path in file operations without validating that it remains in an allowed directory. Valid Avalanche credentials are required, and successful exploitation grants SYSTEM-level command execution on the server.
