CVE-2024-3783Network attack vector

Authenticated file disclosure via path traversal

Published Apr 15, 2024 · Updated Aug 1, 2024

Path traversal in the Backup Agents section of White Bear Solutions WBSAirback 21.02.04 allows remote authenticated users to download system files. Public advisories identify the affected section but do not disclose the request field or path-handling operation that fails to constrain untrusted file paths. Low-privileged access to the network interface is required; exploitation reads files from the underlying system without changing or interrupting it.
