Ivanti Avalanche (Premise) 6.3.2 allows remote unauthenticated users to read arbitrary files via Absolute Path Traversal. The imageFilePath parameter processed by the /AvalancheWeb/image endpoint is not verified to be within the scope of the image folder, e.g., the attacker can obtain sensitive information via the C:/Windows/system32/config/system.sav value.
