CVE-2020-9323Network attack vector

Unauthenticated file enumeration via unrestricted path parameters

Published Mar 18, 2020 · Updated Aug 4, 2024

Path traversal in Aquaforest TIFF Server 4.0 allows remote attackers to enumerate accessible files and directories via tiffserver/tssp.aspx. The ASP.NET form accepts attacker-controlled location parameters and asks IIS to source arbitrary paths without an effective allowlist, exposing directory existence and file counts. The server must expose the form without custom security restrictions; disclosure is limited to paths, existence, and counts accessible to the service account.
