CVE-2021-32532Network attack vector

Unauthenticated file disclosure via unrestricted path parameter

Published Jul 7, 2021 · Updated Sep 16, 2024

Path traversal in QSAN XEVO before 1.2.0 allows remote attackers to download arbitrary system files through its back-end analysis function. The function accepts a caller-supplied file path parameter without restricting it to an intended directory and returns the referenced file. No authentication or user interaction is required, and the demonstrated consequence is read-only disclosure rather than file modification or service interruption.
