Unauthenticated file disclosure via ticket path traversal
Published Mar 13, 2026 · Updated Mar 13, 2026
Path traversal in IceWarp Server 14.2.0.10 allows remote attackers to read sensitive files through the collaboration endpoint. The endpoint uses the unvalidated ticket parameter as a path in file operations, allowing traversal outside the intended directory. No authentication is required, and files readable by the root-context server process can be disclosed.
