CVE-2021-30497Public exploitNetwork attack vector

Arbitrary file read via unchecked image path

Published Apr 6, 2022 · Updated Aug 3, 2024

Path traversal in Ivanti Avalanche (Premise) 6.3.2 allows remote attackers to read arbitrary Windows files through its web interface. The /AvalancheWeb/image endpoint passes the imageFilePath parameter directly to a File object and returns the resulting bytes without restricting the path to the image directory. No authentication is required, so a network request can disclose readable server files, including sensitive operating-system data.
